Pneumatic Oil Filter for Coalescing Applications
The Johnson Controls A-4000-604 is a coalescing pneumatic oil filter rated for 150 psi and 125 Deg F. It removes oil aerosols from compressed air lines with a 0.025 micron filter rating and 99.99 percent efficiency. The unit handles a maximum flow of 20 scfm for industrial air preparation.
Coalescing Element Changes Downstream Air Quality
The coalescing filter element captures fine oil mist that standard particulate filters miss, delivering cleaner air to pneumatic tools and instruments. This reduces contamination in paint systems, prevents valve sticking, and extends the service life of downstream components. The 99.99 percent efficiency rating confirms consistent removal at the rated flow.
Simple Inline Installation with Standard Bowl Access
Installation connects directly into the compressed air line using the filter's inlet and outlet ports. Routine maintenance requires depressurising the system before removing the bowl to replace the coalescing element. Common issues include failing to relieve pressure first or overtightening the bowl, which can damage seals and cause leaks.

Questions about this item
How often should the coalescing filter element be replaced in this A-4000 series filter?
The coalescing element is rated at 99.99 percent efficiency with a .025 micron rating; replacement intervals depend on oil load and operating hours, so monitor pressure drop across the housing and swap the element when differential pressure reaches the manufacturer's service limit.
What is the maximum continuous airflow this filter can handle before pressure drop becomes excessive?
The unit is rated for a maximum flow of 20 scfm at 150 psi and 125 Deg F; sustained operation at or above this flow will increase pressure drop across the coalescing media and signal the need for element change.
How much heat does the filter add to the compressed-air line during all-day operation?
The housing is designed for 125 Deg F maximum inlet temperature; the filter itself adds negligible heat, so outlet temperature remains essentially the same as the incoming air stream under continuous 20 scfm flow.
