Compact Coalescing Filter for Pneumatic Systems

The SPEEDAIRE 4ZL23 is a coalescing filter designed for compressed-air lines in workshops and light industrial settings. It removes oil aerosols and fine particulates to protect downstream tools and equipment. The unit is supplied new and carries California Proposition 65 warnings for cancer and reproductive harm.

Interface and Operating Limits

The filter connects via 1/4 inch NPT female threads on both inlet and outlet with airflow directed left to right. It is rated for a maximum operating pressure of 250 psi and a maximum operating temperature of 150 degrees F. The maximum flow rate is 10.5 cfm, which sets the practical capacity for the circuit.

Installation Checks Before Ordering

Verify that your piping uses 1/4 inch NPT threads and that system pressure and temperature stay within the 250 psi and 150 degrees F limits. Confirm the 10.5 cfm flow rating meets the demand of your tools. The metal bowl includes a manual drain, so plan for accessible maintenance. Buyers needing an automatic drain or a differential pressure indicator should look elsewhere.

Questions about this item

Should I choose the 10.5 cfm filter or a different flow capacity?

The SPEEDAIRE 4ZL23 is rated for a maximum flow of 10.5 cfm. Select it when your pneumatic system runs at or below that flow rate.

What does the 250 psi rating mean when the filter is installed on my compressor?

It means the housing and internals are tested to withstand up to 250 psi. Your compressor regulator must be set at or below this pressure for safe operation.

How does the 1/4 NPT connection affect what hose or pipe I can use?

The filter has 1/4 inch female NPT ports on both inlet and outlet. Use matching male NPT fittings or adapters to connect your air line.
