Johnson Controls A-4000-1048 Filter

The Johnson Controls A-4000-1048 is a high-performance coalescing oil removal filter engineered specifically for high-demand pneumatic control systems. This unit is the designated direct replacement for A-4000-148, ensuring seamless integration into existing service protocols without the need for extensive repiping. With a 3/8" NPT connection size and a 10 SCFM nominal capacity, the A-4000-1048 effectively strips liquid aerosols and solid particles from the compressed air stream, protecting sensitive downstream components from fouling and contamination. Constructed for industrial-grade durability, it maintains a 150 PSIG maximum input pressure and features an automatic drain to discharge accumulated liquids reliably under pressure. When used in series with activated carbon filtration, it provides a superior 0.025 micron rating for oil-free air quality. This component is essential for maintaining the operational integrity of HVAC pneumatic systems and preventing premature failure caused by lubricant carryover from the compressor.

• Direct Replacement: Facilitates an immediate upgrade or maintenance swap for the discontinued A-4000-148 model.
• High Filtration Efficiency: Achieves a 99.999% efficiency rate for removing oil aerosols and particulates down to 0.025 microns.
• Robust Pressure Rating: Rated for a maximum operating pressure of 150 psi at temperatures up to 125°F.
• Automatic Drainage: Equipped with an internal auto-drain mechanism to simplify maintenance and ensure continuous moisture removal.
• Compact Integration: The 3/8" NPT inlet and outlet ports allow for easy installation in tight mechanical rooms or pressure reducing stations.

• Is the A-4000-1048 compatible with older A-4000 series setups? Yes, this unit is the standardized replacement for the older -148 variant and fits the same footprint in Johnson Controls pneumatic stations.
• How often should the coalescing element be replaced? For optimal performance in a standard pneumatic environment, the filter element should be inspected and typically replaced annually to prevent excessive pressure drop.
• Does this filter handle oil vapors as well as liquid aerosols? While primarily designed for aerosols, combining this unit with an activated charcoal filter provides a comprehensive solution for both liquid oil and oil vapors.
