The compression unit in a rotary screw compressor.
Filters incoming air to remove dust and contaminants.
Stores air, stabilizes pressure and system demand.
Cools air after compression to reduce moisture.
Removes oil vapor and odors.
Gauge pressure plus atmospheric pressure.
Third-party parts; may vary in quality.
Indicates compressor shutdown due to fault.
Terms defining moisture, particles, oil, and air purity.
Temperature at which moisture condenses in air.
Pressure at which air exits the compressor.
Percentage of time the compressor is actively running.
Removes moisture from compressed air.
Free Air Delivery; actual air volume delivered under standard conditions.
Immediately shuts down compressor in case of hazard.
Removes oil mist and aerosols from air.
Manages air volume to end-use tools.
Operates at constant speed; simple, cost-effective option.
Regulates the air entering the compressor.
Defines air purity classes based on contaminants.
Procedure to isolate energy sources during maintenance.
Maintains minimum pressure for system stability.
Powers the compressor’s air end.
No oil is present in the compression chamber; critical for clean air applications.
Oil is injected into the compression chamber for cooling and lubrication.
Filters impurities from the lubricating oil.
Compressor is actively compressing air.
Compressor is running but not compressing.
Removes dust and solid particles.
Range between cut-in and cut-out pressures.
Pressure above atmospheric pressure.
Maintains desired downstream pressure.
Prevents over-pressurization.
Uses a piston in a cylinder to compress air; ideal for intermittent, small-scale use.
Releases excess pressure to prevent damage.
Agreement for periodic maintenance and support.
Pre-packaged components for scheduled servicing.
Lubricates compressor; reduces wear and improves performance.
Compressor turns on/off based on pressure limits.
Compresses air in two steps, improving efficiency at higher pressures.
Varies motor speed based on demand; improves energy efficiency.
Separates bulk water from air using centrifugal action.
Manufacturer’s coverage against defects or optional prolonged coverage.
