How to Increase Your Air Compressor CFM for Maximum Efficiency
Stumped by how to increase the CFM of your air compressor? We’ll show you the way, so you can get maximum efficiency from your machine efficiently.
What is cfm of air compressor
CFM meaning Cubic Feet per Minute is the volume of air passing over a unit area and out of a measuring point in one hour, expressed in cubic feet. It is used to rate capacity of blowers and compressors. The higher CFM rating signifies larger capacity blower or compressor, ideal for most applications.
Why is the exhaust volume of the air compressor low?
● intake filter failure：When the intake filter starts to accumulate dirt, the air intake volume decreases and the exhaust gas volume increases; When the intake pipe is too long or the pipe diameter is too small, it will also increase the intake resistance and affect exhaust volume.
● Compressor speed reduction：The discharge capacity of compressor is generally designed according to the intake humidity and altitude. Increasing the discharge capacity can raise the suction pressure and reduce the discharge capacity, but it reduces noise and vibration compared to other methods, so it is more widely used.
● Exhaust valve, compressor failure：If an air valve is contaminated by foreign matter, such as metal fragments, this can lead to a leak. The sources of this issue may be due to the quality of valve parts or the wear on valves and seatings.
● Improper air valve compression force：Improper air valve compression force can cause the gas leakage, too much pressure will make the valve cover deformation damaged. So when the pressure of the air compressor is abnormal, we must conduct a probe and clarify the problem to solve
How to increase the displacement of air compressor?
● inhalation process：In the operation of an air compressor, it is important to ensure that the intake gas is dried as much as possible and that resistance to the intake of compressed air is reduced as much as possible. In addition, we try to keep the sensitivity of the intake valve and exhaust valve of our air compressors so that they can increase their volumetric efficiency.
● cooling effect：When cooling effect is not good, the temperature of the air compressor will rise, and the amount of intake will decrease. It is best to use machines containing advanced refrigeration systems, which is conducive to improving the capacity of air compressors.
● clogging problem：Air compressors are equipped with many parts and areas that can become clogged easily. If left uncleaned and maintained, these parts could clog, thus affecting the cubic feet per minute (CFM) output of the unit. Cleaning and maintaining these parts will not only help you increase CFM output but also save you money by reducing repair and replacement costs.
● speed problem：An increase in speed lowers the pressure volume ratio, with an increase in speed. The relationship between the speed and torque is proportional to the applied electric power, which means that an appropriate increase in centrifugal fan speed can effectively enhance its performance.
