Johnson Controls A-4000-612 Filter Cartridge

The Johnson Controls A-4000-612 is a dry-type replacement filter cartridge engineered for high-performance pneumatic control systems. Designed for intake air filtration, this cartridge features a 10-micron rating with an impressive 99% efficiency, ensuring that solid contaminants are intercepted before they can damage downstream instrumentation or blowers. With a nominal flow capacity of 10 SCFM (up to 15 SCFM in specific configurations), it maintains a low pressure differential to prevent element collapse under high-demand cycles. The rugged construction is specifically compatible with A-4000 Series air filters, which utilize steel housings and baked enamel finishes for durability in both internal and external installations. For contractors maintaining HVAC pneumatic controls, this genuine OEM part is the standard for protecting air compressor accessories and ensuring clean, dry air delivery. Integrating this 10 SCFM filter into your routine maintenance schedule prevents the premature wear of sensitive pneumatic valves and actuators by providing reliable air intake protection.

• High Filtration Efficiency: Maintains 99% efficiency at a 10-micron level to protect sensitive pneumatic components.
• Optimized Airflow: Specifically rated for 10 SCFM to balance effective particulate removal with minimal system pressure drop.
• OEM Compatibility: Direct replacement for A-4000 series intake filters, ensuring a precise fit without field modifications.
• Industrial Durability: Designed to hold its shape under pressure, preventing bypass or cartridge failure in heavy-duty HVACR environments.

What is the connection size for the housing used with this cartridge?
The A-4000-612 cartridge is typically housed in units featuring a 3/4 inch NPT connection, common in standard 10 SCFM pneumatic station setups.

Can this filter be used in outdoor compressor stations?
Yes, when installed in the appropriate A-4000 series steel housing, this filter is suitable for both indoor and outdoor utility locations.

When should this intake filter cartridge be replaced?
Replacement intervals depend on ambient air quality; however, it should be changed whenever a significant pressure drop is detected or during annual pneumatic system calibration to ensure peak performance.
