Johnson Controls A-4000-604 Filter Element

The Johnson Controls A-4000-604 is a professional-grade coalescing filter element designed for high-efficiency oil aerosol removal in pneumatic control systems. Engineered to handle a flow capacity of 20 SCFM, this replacement cartridge is a critical component for maintaining the integrity of downstream instrumentation by preventing oil contamination. It is specifically built for use in A-4000 Series oil removal stations and pressure-reducing setups, ensuring that compressed air remains clean and dry for sensitive HVACR applications.

Constructed with a robust filter media, the A-4000-604 captures sub-micron particles, effectively removing liquid aerosols and vapors. This replacement filter cartridge manages a maximum input pressure of 150 psig and operates reliably in temperatures up to 125°F. For technicians overseeing compressed air systems with copper tubing and four-way bypass valves, this element is the standard for maintaining optimal flow rates and meeting mechanical room fire codes. Regular replacement of this compressed air filter is essential to protect pneumatic actuators and controllers from premature failure caused by lubricant carryover.

Key Benefits for Technicians:

• Effective oil mist removal to prevent fouling of sensitive pneumatic controllers.
• High flow capacity of 20 SCFM ensures minimal pressure drop across the filtration stage.
• Direct compatibility with Johnson Controls A-4000 series stations for seamless maintenance.
• Designed to withstand industrial environments with a 150 psig rating.

Common Questions:

How often should the A-4000-604 coalescing element be replaced?
Technicians typically replace this element annually to maintain system performance, though high-contamination environments may require more frequent intervals to prevent oil bypass.

Is this filter compatible with the activated charcoal stage?
Yes, it is designed to work in tandem with the charcoal filter in the A-4000 series oil removal stations to provide a complete clean-air solution.

Can I use this element in 10 SCFM models?
This specific cartridge is rated for 20 SCFM systems. For smaller 10 SCFM units, ensure you verify the housing size to maintain the correct velocity through the filter media.
