Filter for A-4400 series dryers

The Johnson Controls A-4000-156 is a particulate filter element designed for the A-4400 series pneumatic air dryer. It removes solid contaminants from compressed air systems in HVAC and RV applications. This new component ensures clean, dry air for downstream equipment.

Replaces clogged A-4400 elements

Install this filter when the existing A-4400 cartridge becomes saturated or restricts airflow. The jump is worth it when pressure drop increases or scheduled maintenance intervals arrive. No differential pressure indicator is included with this unit.

Direct cartridge swap

Installation consists of depressurising the dryer housing, removing the spent cartridge, and seating the A-4000-156 in its place. Common issues include failing to relieve system pressure fully or cross-threading the housing bowl during reassembly.
