Air Compressor: What Do You Need to Consider

When it comes to buying an air compressor or upgrading your factory's existing compressed air system, you have a choice between different solutions: lift or rotary vane, oil-free or oil lubricated, controlled speed, or fixed speed.

The compressor provides airflow for all devices in the system. The air compressor works in two phases: compression mode and discharge mode. You can also buy air compressors via

The rate at which the compressor can deliver a volume of air is recorded in cubic feet per minute (cfm). Since atmospheric pressure plays a role in how fast the air moves in the cylinder, the cfm varies based on atmospheric pressure. It also varies depending on temperature and humidity. 

To create a level playing field, manufacturers calculate the standard cubic feet per minute (scfm) as cfm at sea level with 68°F air and 36% relative humidity. SCFM values are reported at certain pressures – for example, 3.0 scfm at 90 psi. If the pressure drops, the scfm increases and vice versa.

The screw compressor is easy to maintain and use. The performance of this compressor is controlled by the variable speed and variable displacement of the compressor. There is a slide in the housing for the most modern control technologies. 

When the compressor power is reduced, the valve opens and directs some of the compressed air back to the suction. The advantages of screw compressors include even, pulseless air output in a compact size with a large output volume for long service life.
