T-Series Low Pressure Screw Compressors
Rated Pressure: 0.15-0.4 MPa, 1.5 -4 Bar, 22-58 psi
Air Flow@ Outlet: 12.8-71 m³/min
Power: 30-280 kW, 40-375 hp
Many industries that require low pressure air still use screw air compressors with a pressure range of 0.7-1.0 MPa, which wastes a significant amount of electricity by using pressure reducing valves to meet the requirements of compressed air usage. In response to the call for energy conservation and emission reduction, Nanxiang has developed low pressure screw air compressor (One stage VSD screw type) based on market demand.
Features of low pressure screw air compressor :
● High performance is guaranteed by using large rotors and low speeds in the machine.
●The cooling area of the oil cooler has been increased by over 30%, ensuring that it can maintain normal operation without overheating during the summer.
●The internal design of the machine was independently developed, optimizing the input-to-power ratio.

Note:
Model number remarks: “F” as fixed speed, “V” as VSD. Due to the potentially different rotation speeds of motors, the air flow rates of fixed speed represent the minimum in the range (i.e 30kW 8 bar 5.67m³/min), while VSD can reach the maximum at full loading.
Standard voltage in 380V (+/-10%), 50Hz +/-2% and available for customized voltage 220/380/440/460V/60Hz.
In cases of elevated altitudes, extreme temperatures, excessive humidity, heavy dust exposure, or any other challenging operational environments, we can offer tailored product designs to meet your specific needs. Customization is available to align with your unique requirements.
High-efficiency Centrifugal Fan (Customized)
The centrifugal fan boasts several advantages, including a large cooling air volume with stable and uniform air pressure. It also has a large heat dissipation area, resulting in a noticeable cooling effect. Additionally, it has overcome the challenge of poor cooling performance in high-power air compressors with wind cooling, and has significantly reduced noise levels by 5-4dB(A).
Energy saving air intake control system
The new specialized design of the integrated air valve includes a wide range of air adjustment, minimal pressure loss, stable operation, and a long lifespan. This compressor is designed to meet the needs of professionals and provide efficient and reliable performance.
cooling system
Equipped with a high-efficiency fin-type large heat exchange area cooler, the compressor boasts a surplus of 30% in heat exchange capacity, resulting in excellent cooling performance. It can operate normally even in an environment with a temperature as high as 45℃.
Increase customized oil separation system
The compressor is equipped with a customized oil separation system to ensure that the air contains less than 3ppm of oil. Additionally, the internal pressure of the compressor is kept low.

Frequently Asked Questions
The low pressure screw air compressor is primarily used in industries that require low air pressure, such as cotton spinning, glass production, cement mixing, and wastewater treatment.
When choosing a low pressure air compressor, consider the Air Delivery ( or CFM ,cubic feet per minute)rating, the horsepower of the motor, the tank size, and the type of pump (oil-lubricated or oil-free). It’s also important to consider the intended use and the environment in which the compressor will be operating.
