Compressed Air Controls | Compressed Air Best Practices

Throttling is usually accomplished by closing the inlet valve, thereby restricting inlet air to the compressor This control scheme is applied to centrifugal and lubricant-injected rotary screw compressors This control method cannot be used on reciprocating or lubricant-free rotary screw compressor and when applied to lubricant-injected rotary screw compressors, is an inefficient means ,

Air Compressors - The Compressed Air Blog

When the orbiting spiral moves, air is drawn in and becomes captured in one of the air pockets where it gradually compresses while moving towards the center The compression cycle continues for 25 turns, which gives almost-constant and pulsation-free air flow This is a relatively silent and vibration-free process, which of course is desirable Centrifugal Compressor: For this compressor type .
