- Coalescing filter removes oil aerosols for cleaner air supply
- 1/4 inch NPT female ports fit standard pneumatic lines
- Rated for 150 psi maximum operating pressure
- 20 cfm maximum flow rate supports moderate air demand
- Polycarbonate bowl with manual drain simplifies maintenance
Compact coalescing filter for point-of-use air
The SPEEDAIRE 4ZL32 installs directly in a 1/4 in NPT line to remove oil aerosols and fine particulates from compressed air. It suits workstations and portable compressors where clean air protects spray guns, airbrushes or pneumatic tools. The polycarbonate bowl lets operators see contamination at a glance.
Rated for 20 cfm at 150 psi
This capacity covers typical hobby and light-industrial outlets running a single tool or spray gun. Flow beyond 20 cfm or pressure above 150 psi exceeds the design limits and will reduce coalescing efficiency. The manual drain requires periodic attention to prevent liquid carry-over.
Left-to-right flow with no differential-pressure
The filter operates passively with no external power, adding negligible pressure drop when clean. Bowl and element temperatures track the compressed-air stream up to 125 °F. Noise contribution is limited to the airflow itself; no moving parts or electrical components are present.

Questions about this item
Will the 1/4 NPT ports on this filter match the fittings on my existing 1/4 NPT airline?
Yes, both the inlet and outlet are 1/4 inch NPT female threads, so they connect directly to standard 1/4 NPT male fittings on your current hose or piping.
How can I confirm the coalescing element is removing oil and water after installation?
Watch the transparent polycarbonate bowl; collected liquid will be visible at the bottom and can be released through the manual drain valve to verify the filter is working.
Does the package include the filter element and bowl, or do I need to buy them separately?
The unit ships as a complete assembly with the coalescing element, polycarbonate bowl and manual drain already installed; no extra parts are required for basic operation.
