Johnson Controls A-4000-633 Filter Element

The Johnson Controls A-4000-633 Filter Element is a critical component for maintaining pneumatic control system integrity. This activated carbon filter element is specifically engineered for high-efficiency oil removal, preventing downstream contamination of sensitive instrumentation. With a rated flow capacity of 20 SCFM (9.4 L/s), it effectively adsorbs oil vapors and odors that mechanical filters often miss. Designed as the direct replacement for the A-4000 oil removal filter series, the A-4000-633 ensures that your compressed air supply meets the stringent requirements of HVACR pneumatic circuits. Utilizing a high-grade charcoal filter element, this unit maintains low pressure drop while maximizing contaminant retention. For technicians servicing industrial air compressors or climate control systems, installing a fresh A-4000-633 carbon filter is essential to prevent seal degradation and calibrate-offset issues caused by oil carryover. Ensure your Johnson Controls pneumatic system remains within original manufacturer specifications by adhering to regular filtration maintenance schedules.

Key Benefits:

• Instrument Grade Air: High-density activated carbon media removes vaporous oil contaminants to protect pneumatic actuators and controllers.
• Optimized Flow Dynamics: Rated for 20 SCFM, providing high-volume filtration without significant line pressure loss.
• Direct Compatibility: Exact fit for Johnson Controls A-4000 series housings, ensuring a leak-proof seal and simplified field replacement.
• Extended Component Life: Prevents "gumming" of sensitive internal orifices and pilot valves by eliminating oil aerosols.

Common Questions:

How often should the A-4000-633 filter element be replaced?
Replacement frequency depends on the oil carryover from your compressor, but standard practice dictates replacement when downstream odors are detected or during annual preventative maintenance to ensure peak oil removal filter performance.

Is this element compatible with other filter brands?
The A-4000-633 is a proprietary Johnson Controls part designed specifically for the A-4000 series canisters. Using non-specified elements may compromise the 20 SCFM flow rate and filtration efficiency.

Does this filter remove water or particulate?
While the charcoal filter element may trap some residual fine particles, its primary function is activated carbon adsorption of oil vapors. It should be used in conjunction with a moisture separator and a standard particulate pre-filter for full system protection.
