SPEEDAIRE 4ZL22 Coalescing Filter
The SPEEDAIRE 4ZL22 is a coalescing pneumatic oil filter designed to remove oil aerosols and fine particulates from compressed air lines. It features a 2 inch NPT female inlet and outlet, supporting a maximum flow rate of 600 cfm at pressures up to 250 psi. The heavy-duty metal bowl includes an automatic drain for continuous operation.
Installations needing oil-free air
This filter suits compressed air systems requiring high-efficiency oil coalescing at flow rates up to 600 cfm and 250 psi operating pressure. The automatic drain reduces maintenance intervals in continuous-duty applications. Systems requiring a differential pressure indicator for element monitoring or a maximum operating temperature above 150 degrees F should look at alternative filtration solutions.
600 cfm maximum flow capacity
The 600 cfm maximum flow rate is the primary specification that determines if this filter matches the system demand. Exceeding this flow rating will reduce coalescing efficiency and increase pressure drop across the element. Verify the compressor output and downstream air consumption against this figure before installation.

Questions about this item
How often does the coalescing filter element need to be replaced?
Replace the element when pressure drop across the housing reaches the limit recommended for coalescing service; the unit has no built-in differential pressure indicator.
What flow ceiling should I stay under to avoid excessive pressure drop?
The housing is rated for 600 cfm maximum flow; operating near that limit will increase differential pressure and shorten element life.
How much heat can the metal bowl and seals handle during continuous operation?
Maximum operating temperature is 150 degrees F; the metal bowl and automatic drain are designed for that sustained temperature.
