Charcoal Filter for HVAC Controls
The Johnson Controls A-4000-632 is a replacement charcoal filter element designed for HVAC control systems. It uses activated charcoal media to remove oil vapour and odours from compressed air lines. The transparent housing allows visual inspection of the element condition. Rated for a maximum flow of 10 scfm, it suits pneumatic control circuits requiring clean, oil-free air.
Suited for Oil-Removal Applications
This filter targets installers and maintenance teams needing 0.025 micron filtration for oil-type fluids in pneumatic controls. It is not intended for particulate-only filtration, water separation, or high-flow industrial mains exceeding the rated capacity. Buyers requiring coalescing elements, bulk liquid removal, or different micron ratings should select an alternative filter type.
Sustained Flow Behaviour
Under continuous 10 scfm operation, the charcoal media adsorbs oil vapour consistently until saturation reduces efficiency. Pressure drop increases gradually as the element loads, signalling replacement need. The element maintains its 0.025 micron rating throughout its service life provided flow stays within the specified maximum. Regular inspection through the transparent body supports planned change-outs.

Questions about this item
What HVAC control series must I already have for the A-4000-632 charcoal filter element to fit?
The filter is designed for the A 4000 series HVAC controls, so that series must be installed for proper fit.
Will the 0.025 micron charcoal rating restrict flow in an older 10 scfm oil system?
The element is rated for a maximum flow of 10 scfm with oil, matching the original specification for that series.
How can I confirm the filter is working after installation?
Verify that oil flows through the transparent housing at up to 10 scfm without pressure drop or visible contamination downstream.
