Compact coalescing oil filter for low-flow air lines

The SPEEDAIRE 4ZL16 is a miniature pneumatic oil filter rated for 6 cfm at 150 psi. Its coalescing element removes oil aerosols and fine particles from compressed air systems. The 1/8 inch NPT female ports suit point-of-use installations on machinery or workstations. It operates up to 125 degrees Fahrenheit.

Manual drain and polycarbonate bowl simplify daily

A manual drain valve lets operators expel collected condensate without tools. The transparent polycarbonate bowl provides instant visual confirmation of fluid level and element condition. Left-to-right flow direction is fixed, so piping must match the arrow on the head. No differential pressure indicator is fitted.

Verify port size pressure

Confirm your supply line uses 1/8 inch NPT threads and that system pressure stays at or below 150 psi. Ensure ambient and compressed-air temperatures do not exceed 125 degrees Fahrenheit. The polycarbonate bowl is not compatible with synthetic lubricants or aggressive solvents. Buyers needing higher flow rates or automatic draining should select a larger series.

Questions about this item

How often should the coalescing filter element be replaced on the 6 cfm unit?

Replace the element when pressure drop across the filter reaches the manufacturer's recommended limit or at the interval specified in the service manual.

Will the 150 psi pressure rating hold during continuous operation?

The housing is rated for 150 psi maximum operating pressure; sustained use must stay at or below this limit.

Does the polycarbonate bowl handle 125 °F ambient temperatures without deforming?

The bowl is rated for a maximum operating temperature of 125 °F, so continuous operation at that temperature is within specification.
