Yet many operators give little thought to the fluid circulating inside these machines until performance drops or the pump fails outright. Because oil serves as both a lubricant and a sealing medium in most vacuum pump designs, choosing the wrong fluid can raise the ultimate pressure the pump can reach, accelerate wear on precision components, and shorten equipment life far more quickly than almost any other operating mistake.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Most vacuum pumps use specially refined, low-vapor-pressure oil, typically either distilled mineral oil or synthetic oil, formulated specifically for vacuum applications. Distilled mineral oil, refined through single, double, or triple distillation to remove sulfur and other volatile impurities, is the standard choice for oil-sealed rotary vane pumps, while synthetic oils such as polyalphaolefins and perfluoropolyethers are reserved for high-temperature, high-vacuum, or chemically aggressive environments. Ordinary motor oil, hydraulic fluid, or general-purpose lubricating oil should never be used, because their high vapor pressure and additive packages destroy vacuum performance.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The sections below explain what separates vacuum pump oil from ordinary lubricants, the main oil categories and their applications, how to match oil to your pump type, and what to do if you run out of the correct fluid.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why Vacuum Pump Oil Is Different from Ordinary Oil<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Vacuum pump oil differs from ordinary lubricating oil because it must do two jobs at once: lubricate moving parts and create the airtight seal that makes deep vacuum possible. It also has to resist evaporation under extreme low pressure, something ordinary oils were never designed to do.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In an oil-sealed vacuum pump, the oil fills the gap between the vanes, rotor, and cylinder wall, sealing each compression chamber so gas cannot leak backward from the exhaust side to the inlet side. Without this oil seal, the pump could never pull a vacuum below atmospheric pressure in any practical timeframe. The oil simultaneously carries heat away from friction surfaces, flushes debris out of the pumping chamber, and coats internal metal surfaces to block moisture and corrosion.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Three properties determine whether a fluid can perform these duties in industrial <a href=\"https:\/\/nxcompressor.com\/it\/product\/vacuum-pumps\/\">vacuum pumps<\/a>:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Vapor pressure.<\/strong> The lower the vapor pressure, the deeper the vacuum the oil can support. A fluid that evaporates easily under low pressure releases vapor right back into the pumping chamber, which places a hard floor on the vacuum level the system can reach. Quality vacuum pump oil has a vapor pressure orders of magnitude lower than that of ordinary lubricating oil.<\/li>\n\n\n\n<li><strong>Viscosity.<\/strong> The oil must be thick enough to maintain the seal at operating temperature yet thin enough to circulate and dissipate heat. Medium viscosity suits warmer operating environments, while lower viscosity performs better in cooler conditions. Viscosity is graded under the ISO VG system, with ISO VG 46 and ISO VG 68 among the most common grades for rotary vane vacuum pumps.<\/li>\n\n\n\n<li><strong>Purity and chemical stability.<\/strong> Sulfur compounds, dissolved water, and other impurities evaporate under vacuum and contaminate both the pump and the process. Refining and additive chemistry determine how clean and how chemically inert the oil remains over its service life.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img fetchpriority=\"high\" decoding=\"async\" width=\"600\" height=\"600\" src=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/05\/vacum_pump.webp\" alt=\"pompa_vuoto\" class=\"wp-image-24351\" style=\"width:350px;height:auto\" srcset=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/05\/vacum_pump.webp 600w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/05\/vacum_pump-300x300.webp 300w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/05\/vacum_pump-150x150.webp 150w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/05\/vacum_pump-12x12.webp 12w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Types of Vacuum Pump Oil<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Vacuum pump oil falls into four main categories: distilled mineral oil, synthetic oil, semi-synthetic oil, and specialty fluids. The right category depends on your pump design, the vacuum depth you need, and the process conditions the pump faces.<\/strong><\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Mineral Oil<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Mineral vacuum pump oil starts as petroleum base stock and is purified through distillation, a process that removes sulfur and other volatile contaminants to lower vapor pressure. The number of distillation passes defines the grade, as industry training resources such as <a href=\"https:\/\/vacaero.com\/information-resources\/vac-aero-training\/24460-vacuum-pump-oil.html\" target=\"_blank\" rel=\"noopener\">Vac Aero<\/a> explain in detail:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Single-distilled oil<\/strong> retains a light brown color and reaches an ultimate vacuum of roughly 10 microns. It suits single-stage rotary vane pumps in less demanding applications.<\/li>\n\n\n\n<li><strong>Double-distilled oil<\/strong> is lighter in color, contains less sulfur, and reaches about 1 micron, making it the standard for most two-stage vacuum pumps.<\/li>\n\n\n\n<li><strong>Triple-distilled oil<\/strong> is chemically inert, nearly transparent, and rated for about 0.6 micron or better, serving continuous-duty and higher-vacuum applications.<\/li>\n\n\n\n<li><strong>Hydrotreated oil<\/strong> is refined under high pressure and temperature with hydrogen, achieving the highest purity among mineral-based fluids. It is used in industrial and scientific high-vacuum work but does not always blend well with the additive packages that trade-specific pumps require.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Synthetic Oil<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Synthetic oils are engineered from uniform molecular building blocks rather than refined from crude petroleum, so their viscosity and chemical behavior stay consistent across a wide temperature range. Polyalphaolefin (PAO) based synthetics deliver strong thermal stability and oxidation resistance for demanding general industrial service, diester and ester-based fluids improve lubricity at temperature extremes, and perfluoropolyether (PFPE) fluids remain inert even in the presence of aggressive chemicals such as chlorine or hydrogen peroxide. Synthetic oils cost more upfront, but their longer service life and better protection under harsh conditions often reduce total cost of ownership.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Semi-Synthetic and Specialty Oils<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Semi-synthetic oils blend mineral and synthetic base stocks to balance performance and price, offering better oxidation resistance than plain mineral oil at a moderate cost premium. Specialty fluids round out the category for particular industries: food-grade oils formulated to FDA and NSF standards for food and pharmaceutical processing, low-vapor-pressure oils that minimize outgassing in high-vacuum environments, and corrosion-resistant formulations for humid or chemically exposed installations.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Oil Type<\/td><td>Base<\/td><td>Vapor Pressure<\/td><td>Ideale per<\/td><td>Costo relativo<\/td><\/tr><tr><td>Single-distilled mineral<\/td><td>Refined petroleum<\/td><td>Moderato<\/td><td>Single-stage pumps, general duty<\/td><td>Basso<\/td><\/tr><tr><td>Double\/triple-distilled mineral<\/td><td>Highly refined petroleum<\/td><td>Basso<\/td><td>Two-stage pumps, deeper vacuum<\/td><td>Da basso a medio<\/td><\/tr><tr><td>Synthetic (PAO, ester)<\/td><td>Engineered hydrocarbons<\/td><td>Molto basso<\/td><td>High temperature, continuous duty<\/td><td>Alto<\/td><\/tr><tr><td>Synthetic (PFPE)<\/td><td>Fluorinated fluid<\/td><td>Extremely low<\/td><td>Corrosive and chemical processes<\/td><td>Molto alto<\/td><\/tr><tr><td>Semi-synthetic<\/td><td>Mineral plus synthetic blend<\/td><td>Low to moderate<\/td><td>Mixed duty, cost-sensitive use<\/td><td>Medio<\/td><\/tr><tr><td>Specialty (food grade, low outgassing)<\/td><td>Application-specific<\/td><td>Variabile<\/td><td>Regulated or specialized processes<\/td><td>Variabile<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\">Is Vacuum Pump Oil Just Mineral Oil?<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No. Although many vacuum pump oils use a mineral base, they are not the same as the ordinary <a href=\"https:\/\/en.wikipedia.org\/wiki\/Mineral_oil\" target=\"_blank\" rel=\"noopener\">mineral oil<\/a> found on a hardware shelf. Vacuum pump oil is refined to a far higher purity and blended with additive packages that control oxidation, foaming, and lubricity, all while keeping vapor pressure low enough to support deep vacuum.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The refining gap matters in practice. Drugstore mineral oil or generic machine oil contains sulfur compounds, waxes, and moisture that boil off under vacuum, contaminating the process and preventing the pump from reaching its rated depth. Even hydraulic fluid and turbine oil, which look similar and flow similarly, contain detergent and anti-foam additives designed for entirely different pressure environments. Substituting any of them for purpose-formulated vacuum pump oil trades a small saving today for lost performance and accelerated pump wear tomorrow.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img decoding=\"async\" width=\"768\" height=\"768\" src=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2025\/11\/10002-2.webp\" alt=\"\" class=\"wp-image-20287\" style=\"aspect-ratio:1.4992931672837428;width:403px;height:auto\" srcset=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2025\/11\/10002-2.webp 768w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2025\/11\/10002-2-300x300.webp 300w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2025\/11\/10002-2-150x150.webp 150w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Do All Vacuum Pumps Use the Same Oil?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>No. The correct oil depends on the pump design, and using the wrong fluid in a given pump type can cause anything from poor vacuum depth to complete failure. Oil-sealed pumps depend on oil as a working seal, while dry pumps need only bearing and gear lubrication, and liquid ring pumps may not need oil in the pumping chamber at all.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The most common design, the oil-sealed <a href=\"https:\/\/en.wikipedia.org\/wiki\/Rotary_vane_pump\" target=\"_blank\" rel=\"noopener\">rotary vane pump<\/a>, uses oil sprayed onto vanes and cylinder walls to seal and lubricate the compression chamber, so it demands oil with the right viscosity and vapor pressure profile described above. Dry screw, dry vane, and claw pumps keep oil out of the pumping chamber entirely and instead rely on grease or synthetic gear oil for bearings and timing gears, where low-outgassing formulations matter in clean environments such as laboratories and semiconductor fabrication. Liquid ring pumps typically use water as the sealing fluid, though oil-sealed versions exist for processes where the vapor pressure of water would limit the achievable vacuum, and those require moisture-resistant oil with anti-emulsification and anti-foaming additives.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This mirrors the broader compressed-air landscape, where the choice between <a href=\"https:\/\/nxcompressor.com\/it\/oil-lubricated-air-compressors-vs-oil-free-air-compressor-which-is-better\/\">compressori d'aria lubrificati a olio<\/a> and oil-free designs determines not only the lubricant strategy but also the downstream air quality and maintenance burden. The table below summarizes how pump design drives lubricant selection.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><tbody><tr><td>Pump Type<\/td><td>Oil in Pumping Chamber<\/td><td>Typical Lubricant Requirement<\/td><\/tr><tr><td>Oil-sealed rotary vane<\/td><td>Yes, oil is the seal<\/td><td>Distilled mineral or synthetic vacuum pump oil<\/td><\/tr><tr><td>Dry screw or dry claw<\/td><td>No<\/td><td>Low-outgassing grease for bearings and gears<\/td><\/tr><tr><td>Liquid ring<\/td><td>Usually water or compatible service liquid<\/td><td>Moisture-resistant oil with anti-foam additives if oil-sealed<\/td><\/tr><tr><td>Diaframma<\/td><td>No<\/td><td>Grease for bearings only<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">What Can You Substitute for Vacuum Pump Oil?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>There is no good substitute for vacuum pump oil. Motor oil, hydraulic fluid, transmission fluid, and household mineral oil all have vapor pressures far too high for vacuum work, and their detergent additives can leave deposits inside the pump. If you run out of the correct oil, the safest option is to stop the pump and obtain the specified fluid rather than improvise.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding why substitution fails is straightforward when you compare formulations. <a href=\"https:\/\/nxcompressor.com\/it\/what-type-of-oil-does-an-air-compressor-use\/\">Air compressor oil<\/a> in particular, while chemically related, is blended for positive pressure service where vapor pressure barely matters, so it evaporates freely once a vacuum is drawn and the pump stalls well above its rated depth. Motor oil adds detergents and dispersants designed to suspend combustion byproducts, and those additives foam and outgas under vacuum. Hydraulic fluid contains anti-wear additives that can react with process gases.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In an emergency, a higher-grade distilled vacuum pump oil can usually stand in for a lower grade in the same family, for example triple-distilled in place of double-distilled, because the chemistry remains compatible. What you should never do is top up a partial fill with a different base type, since mineral and synthetic fluids often do not mix and the blend can separate, foam, or leave varnish inside the pump. If contamination from previous improper oil is suspected, run a dedicated flushing fluid, a solvent-rich oil with a high concentration of cleaning additives, briefly through the pump before refilling with the correct oil. Flushing fluid removes water, oxides, and residue but is not a substitute for operating oil.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img decoding=\"async\" width=\"1536\" height=\"1024\" src=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2.webp\" alt=\"How to Choose the Right Vacuum Pump Oil\" class=\"wp-image-26362\" style=\"aspect-ratio:1.4992931672837428;width:681px;height:auto\" srcset=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2.webp 1536w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2-300x200.webp 300w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2-18x12.webp 18w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2-768x512.webp 768w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2026\/10\/How-to-Choose-the-Right-Vacuum-Pump-Oil-2-1024x683.webp 1024w\" sizes=\"(max-width: 1536px) 100vw, 1536px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">How to Choose the Right Vacuum Pump Oil<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>To choose the right oil, match four variables: your pump design, the vacuum depth the process requires, the operating temperature range, and the manufacturer&#8217;s viscosity specification. When any of these factors conflict, the manufacturer&#8217;s recommendation takes precedence.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A practical selection process looks like this:<\/p>\n\n\n\n<ol class=\"wp-block-list\">\n<li><strong>Confirm the pump type.<\/strong> Oil-sealed rotary vane pumps need sealed-chamber oil; dry pumps need grease or gear oil only for bearings and gears.<\/li>\n\n\n\n<li><strong>Check the vacuum requirement.<\/strong> Rough vacuum work tolerates single-distilled oil, while deeper processes demand double- or triple-distilled or synthetic fluids with lower vapor pressure.<\/li>\n\n\n\n<li><strong>Match the viscosity grade.<\/strong> Follow the ISO VG rating in the pump manual, choosing the lower end of the approved range for cold environments and the higher end for hot environments.<\/li>\n\n\n\n<li><strong>Assess the operating environment.<\/strong> Humidity calls for moisture-resistant oil with anti-emulsifiers, dust favors fluids with dispersant additives, and chemical exposure may require inert PFPE synthetics.<\/li>\n\n\n\n<li><strong>Verify compatibility with process gases.<\/strong> Pumps handling corrosive or reactive gases need oils that will not break down when exposed to them.<\/li>\n<\/ol>\n\n\n\n<p class=\"wp-block-paragraph\">Operating conditions matter as much as the pump itself. Extreme heat thins oil and degrades its protective film, extreme cold thickens it and slows circulation, moisture emulsifies inadequate oils, and airborne dust contaminates them. Each condition points toward a specific class of lubricant, which is why the same pump model may run on three different oils in three different factories.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">When to Change Vacuum Pump Oil<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Change vacuum pump oil when it turns dark, becomes cloudy or milky, smells burnt or sour, or at the interval specified in your pump manual, whichever comes first. For most industrial pumps in regular service, that means an oil change every few hundred to a few thousand running hours, and far sooner for processes that pull a lot of moisture or solvents through the pump.<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Fresh vacuum pump oil is nearly transparent with a light amber tint. As it works, it darkens as it absorbs contaminants and oxidation products. A milky appearance means water has condensed into the oil, a common result of evacuating wet systems, and continued running on emulsified oil both degrades vacuum depth and promotes internal corrosion. Visible particles, a varnish smell, or an oil level that keeps dropping all signal that the fluid is past its useful life.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Good habits extend oil life considerably: let the pump run with the gas ballast open when evacuating moist systems so water vapor exits instead of condensing, change the oil while it is warm so contaminants drain fully, and keep the pump inlet filtered. Oil condition is one of the cheapest indicators of overall equipment health, and treating it as part of a broader <a href=\"https:\/\/nxcompressor.com\/it\/how-to-maintain-an-air-compressor-complete-maintenance-guide\/\">air compressor maintenance<\/a> routine keeps both vacuums and pressures where they should be.<\/p>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full is-resized\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"768\" src=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2024\/04\/\u771f\u7a7a\u6cf5-1jpg-768x768-1.webp\" alt=\"pompa a vuoto\" class=\"wp-image-18461\" style=\"aspect-ratio:1.4992931672837428;width:492px;height:auto\" srcset=\"https:\/\/nxcompressor.com\/wp-content\/uploads\/2024\/04\/\u771f\u7a7a\u6cf5-1jpg-768x768-1.webp 768w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2024\/04\/\u771f\u7a7a\u6cf5-1jpg-768x768-1-300x300.webp 300w, https:\/\/nxcompressor.com\/wp-content\/uploads\/2024\/04\/\u771f\u7a7a\u6cf5-1jpg-768x768-1-150x150.webp 150w\" sizes=\"(max-width: 768px) 100vw, 768px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Domande frequenti<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Can you mix mineral and synthetic vacuum pump oil?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Mixing mineral and synthetic vacuum pump oil is not recommended. The two base stocks often have limited mutual solubility, so the blend can separate, foam, or leave varnish deposits inside the pump, and the resulting vapor pressure will be unpredictable. If you must switch from one to the other, drain the old oil completely, flush the pump with a compatible flushing fluid or a small charge of the new oil, and refill with the new type only.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What viscosity is standard vacuum pump oil?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Most oil-sealed rotary vane vacuum pumps use oil in the ISO VG 46 to ISO VG 68 range, with smaller and laboratory-grade pumps often specifying thinner grades around ISO VG 22 to 32. The exact grade depends on the pump design and operating temperature, so the manufacturer&#8217;s specification should always be followed. Using a viscosity that is too high slows circulation and weakens the seal at startup, while a viscosity that is too low allows internal leakage and raises the attainable pressure.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Does vacuum pump oil expire?<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Yes, vacuum pump oil has a finite shelf life, typically two to three years in a sealed container stored away from heat, light, and moisture. Once opened, the container begins absorbing humidity from the air, and dissolved water raises the vapor pressure of the oil even if it looks clean. Date your containers when opened, keep them tightly sealed, and discard oil that shows any cloudiness, sediment, or off smell rather than risking it in the pump.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Vacuum pumps sit at the heart of countless industrial processes, from food packaging and plastics molding to semiconductor manufacturing and [&hellip;]<\/p>\n","protected":false},"author":20,"featured_media":23169,"comment_status":"open","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"site-sidebar-layout":"default","site-content-layout":"","ast-site-content-layout":"default","site-content-style":"default","site-sidebar-style":"default","ast-global-header-display":"","ast-banner-title-visibility":"","ast-main-header-display":"","ast-hfb-above-header-display":"","ast-hfb-below-header-display":"","ast-hfb-mobile-header-display":"","site-post-title":"","ast-breadcrumbs-content":"","ast-featured-img":"","footer-sml-layout":"","ast-disable-related-posts":"","theme-transparent-header-meta":"","adv-header-id-meta":"","stick-header-meta":"","header-above-stick-meta":"","header-main-stick-meta":"","header-below-stick-meta":"","astra-migrate-meta-layouts":"default","ast-page-background-enabled":"default","ast-page-background-meta":{"desktop":{"background-color":"var(--ast-global-color-5)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"ast-content-background-meta":{"desktop":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"tablet":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""},"mobile":{"background-color":"var(--ast-global-color-4)","background-image":"","background-repeat":"repeat","background-position":"center center","background-size":"auto","background-attachment":"scroll","background-type":"","background-media":"","overlay-type":"","overlay-color":"","overlay-opacity":"","overlay-gradient":""}},"footnotes":""},"categories":[40,35],"tags":[],"class_list":["post-26338","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-compressor-academy","category-instructions"],"acf":[],"permalink_manager":null,"_links":{"self":[{"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/posts\/26338","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/users\/20"}],"replies":[{"embeddable":true,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/comments?post=26338"}],"version-history":[{"count":8,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/posts\/26338\/revisions"}],"predecessor-version":[{"id":26368,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/posts\/26338\/revisions\/26368"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/media\/23169"}],"wp:attachment":[{"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/media?parent=26338"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/categories?post=26338"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/nxcompressor.com\/it\/wp-json\/wp\/v2\/tags?post=26338"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
