Johnson Controls A-4000-1037 Filter

As a seasoned technician, you know that keeping oil aerosols and vapors out of pneumatic lines is non-negotiable for system longevity. The Johnson Controls A-4000-1037 is a critical inline oil removal filter designed specifically for pneumatic control systems where air purity is paramount. Featuring a 1/4" barb connection, this compact unit serves as a high-efficiency coalescing filter that traps sub-micron oil particles before they can foul sensitive controllers or actuators. With a maximum flow capacity of 2600 scim and a pressure rating of up to 125 psig, it provides the industrial-grade performance needed in demanding HVACR mechanical rooms. By integrating both coalescing and activated charcoal filtration stages, the A-4000-1037 ensures the air supply is virtually free of contaminants. This is an essential component for any contractor maintaining legacy or modern pneumatic networks who requires a reliable Johnson Controls replacement filter to prevent costly downtime and equipment failure.

• Dual-Stage Filtration: Combines coalescing action with activated carbon to remove both liquid oil aerosols and gaseous vapors.
• High Capacity: Handles up to 2600 scim, making it suitable for standard pneumatic branch lines.
• Durable Construction: Rated for up to 125 psig and temperatures reaching 125°F (52°C) for harsh environment stability.
• Simple Installation: Standard 1/4" barb connections allow for quick inline replacement without complex refitting.

• What is the primary application for the A-4000-1037? It is used in pneumatic HVAC control systems to protect instruments from oil contamination originating from the air compressor.
• Can this filter be used on the high-pressure side? It is rated for a maximum input pressure of 125 psig; always verify your regulator settings before installation.
• When should this inline filter be replaced? For optimal performance in pneumatic systems, technicians typically replace these filters during annual maintenance or whenever oil discoloration is visible in the lines.
