Johnson Controls A-4000-605 Filter Element

The Johnson Controls A-4000-605 is a high-performance coalescing filter element engineered for critical moisture and oil aerosol removal in pneumatic control systems. Rated for a 40 SCFM flow rate, this element ensures your downstream instrumentation remains free from contaminants that cause sticky valves and system drift. Designed for a maximum pressure of 150 psi and operating temperatures up to 125°F, it features a 0.025 micron filtration rating with an impressive 99.99% efficiency. As a primary pneumatic oil filter replacement for the A-4000 series stations, it is essential for maintaining the clean, dry air required by precision HVAC controllers. For optimal system performance, contractors should monitor the differential pressure; a drop of 15 psi or a leaving pressure below 50 psig typically indicates the element is saturated and requires immediate replacement. This genuine Johnson Controls A-4000-605 replacement helps prevent costly pneumatic component failures and extends the service life of your entire air-driven control network.

• High-Efficiency Coalescing: Removes 99.99% of oil aerosols down to 0.025 microns to protect sensitive pneumatic thermostats and actuators.
• Optimized Flow Capacity: Supports up to 40 SCFM, making it compatible with larger pneumatic air compressor stations and multi-zone systems.
• Durable Construction: Built to withstand industrial pneumatic environments with a maximum operating pressure of 150 psi.
• Direct OEM Fit: Specifically designed for the Johnson Controls A-4000 series, ensuring a perfect seal and proper interface with automatic drains.

• When should the A-4000-605 element be replaced? It should be swapped when the pressure differential between input and output gauges reach 15 psi or when the output pressure falls below 50 psig.
• Does this filter handle oil vapor? While this coalescing element is superior for removing oil aerosols and liquid droplets, an activated charcoal filter is typically used in series if total vapor removal is required.
• Is this compatible with all A-4000 stations? This 40 SCFM model is the direct replacement for the large-capacity housings in the A-4000 series; always verify your station's specific flow rating before installation.
