Johnson Controls A-4110-604 pneumatic filter

The Johnson Controls A-4110-604 is a coalescing pneumatic replacement filter rated at 0.025 micron for oil removal. It serves maintenance technicians and facility engineers who need clean, dry compressed air for sensitive pneumatic instruments and processes. The filter element handles a maximum flow of 10 scfm within the A 4000 series housing. It installs directly into existing filter bowls designed for this series.

Upgrading from standard particulate filters

This filter replaces basic particulate elements when oil aerosols and fine mist must be captured down to 0.025 micron. The jump is worth it when downstream equipment such as air bearings, spray guns or analysers show contamination or premature wear. Standard filters pass oil vapour that this coalescing media traps, reducing maintenance on valves and actuators. It does not suit systems needing only bulk water separation or higher flow capacities beyond 10 scfm.

Simple drop-in element swap

Installation requires depressurising the line, unscrewing the bowl, and swapping the used element for the new A-4110-604. The coalescing media must face the correct flow direction marked on the housing. Common issues include forgetting to lubricate the bowl O-ring, which causes leaks, or overtightening the bowl and cracking the plastic. Always verify the housing is an A 4000 series match before fitting.

Questions about this item

What series and model number does the A-4110-604 filter fit?

The filter is built for the A 4000 series and carries the model number 4110-604, so it installs directly into that housing.

How is the filter installed, and what step is often missed?

Remove the old element, insert the new coalescing cartridge with the flow arrow pointing downstream, then re-seat the bowl and tighten the retaining ring until the O-ring seats evenly — skipping the arrow check lets oil bypass the media.

When will the 0.025 micron coalescing element need replacement?

Replace the element when the pressure drop across the filter reaches the system’s change-out limit or at the scheduled preventive-maintenance interval for 10 scfm oil-service applications.
