Johnson Controls A-4000-6001 Coalescing Filter

The Johnson Controls A-4000-6001 Coalescing Filter is a critical component for maintaining high-purity pneumatic control systems. Engineered to handle a flow rate of 40 SCFM, this high-performance filter provides industry-leading air quality by achieving 99.999% efficiency for particulates 0.025 microns and larger. Specifically designed to remove oil aerosols and sub-micronic contaminants, it protects sensitive downstream instruments from fouling and mechanical failure. This model serves as the direct replacement for the Johnson Controls A-4000-601, ensuring seamless integration into existing compressed air systems without requiring extensive piping modifications. For technicians managing HVAC pneumatic air lines, this filter is essential for preventing the sludge buildup that leads to stuck actuators and calibrated drift. The robust construction and precise filtration media make it a standard for clean-air applications where compressed air filtration integrity is non-negotiable.

Key Benefits

• Ultra-High Efficiency: Captures 99.999% of contaminants down to 0.025 microns for superior system protection.
• High Flow Capacity: Supports 40 SCFM, making it suitable for larger commercial pneumatic systems.
• Direct Interchangeability: Designed as a drop-in A-4000-601 replacement for simplified field maintenance.
• Aerosol Removal: Effectively eliminates oil and moisture mist to ensure clean, dry air for pneumatic controls.
• System Longevity: Reduces maintenance cycles by preventing particulate accumulation in delicate valve assemblies.

Common Questions

How often should the A-4000-6001 coalescing filter be replaced?
Technicians should monitor the pressure drop across the filter housing. A significant increase in differential pressure indicates the media is saturated and requires replacement to maintain optimal SCFM flow.

Can this filter handle liquid water quantities?
While the coalescing media is highly effective at removing aerosols, it is recommended to have a standard moisture separator upstream for heavy liquid loads to extend the life of the coalescing filter element.

Is this compatible with older Johnson Controls HVAC systems?
Yes, it is the designated OEM replacement for the discontinued A-4000-601, ensuring full compatibility with existing Johnson Controls pneumatic installations.
