Air Intake Filter Element Replacement – 6211472350

The 6211472350 Air Intake Filter Element is a genuine/OEM-style air filter designed for Atlas Copco, Chicago Pneumatic, ABAC, and Quincy oil-injected rotary screw air compressors. It removes dust, dirt, moisture-borne particles, and other airborne contaminants from the intake air before it enters the compressor’s air end. The high-efficiency pleated paper filter media provides excellent filtration with low airflow resistance, helping maintain compressor performance, reduce energy consumption, and extend the service life of critical components such as the air end, bearings, and seals. It is commonly used on Chicago Pneumatic QRS 20, QRS 25, QRS 30, and compatible compressor models.

Working Process

1. Air Intake
   • Ambient air is drawn into the compressor through the intake filter.
2. Particle Filtration
   • The pleated filter media captures dust, dirt, pollen, and other contaminants while allowing clean air to pass with minimal restriction.
3. Clean Air Supply
   • Filtered air flows into the compressor air end, where it is compressed efficiently.
4. Component Protection
   • Clean intake air prevents abrasive particles from damaging rotors, bearings, seals, and other internal components, reducing wear and maintenance costs.
5. Maintenance
   • As contaminants accumulate, airflow restriction increases. The filter should be inspected regularly and typically replaced every 2,000 operating hours, or sooner in dusty environments, to maintain optimum compressor efficiency.
