- Mist lubrication extends tool life with consistent oil delivery
- 114 cfm maximum flow supports high-demand pneumatic applications
- 150 psi operating pressure handles heavy-duty compressed air systems
- Polycarbonate bowl with steel guard resists impact and chemical exposure
- Sight dome and gauge allow instant oil level monitoring
3/8 in air line lubricator
The SPEEDAIRE 4ZL85 is a Standard Duty compressed-air lubricator built for inline installation. Its aluminum body and polycarbonate bowl with steel guard suit workshop and light-industrial air systems. A 3/8 in NPT inlet feeds a maximum flow of 114 cfm at up to 150 psi. The unit ships new and includes a sight dome and sight gauge for oil-level monitoring.
Verify port size pressure and flow
Confirm that the existing line uses 3/8 in NPT threads and that system pressure does not exceed 150 psi. The lubricator handles 114 cfm maximum flow, so the compressor and downstream tools must stay within that rate. Operating temperature must remain at or below 125 °F. Oil adjustment uses a screwdriver mechanism, so keep a suitable driver accessible at the install point.
Steady mist delivery at rated limits
Under continuous operation the mist-type lubricator meters oil through the PE adjustment screw while the sight dome lets the operator confirm consistent atomisation. The aluminum body and guarded polycarbonate bowl maintain integrity at the 150 psi ceiling and 125 °F temperature limit. Flow remains stable up to the 114 cfm rating without the pressure spikes seen in short-burst cycling.

Questions about this item
What comes in the box with the SPEEDAIRE 4ZL85 lubricator and what must be purchased separately?
The unit includes a polycarbonate bowl with steel guard, aluminium body, sight dome and sight gauge. Fittings, tubing, airline oil and mounting hardware are not supplied.
How do I decide between the 80 cfm and 114 cfm flow ratings for the 4ZL85?
The nameplate shows 80 cfm while the detailed spec lists 114 cfm maximum flow. Size the lubricator to the actual system demand; choose the higher figure only if your compressor regularly delivers that volume.
What does the 150 psi maximum operating pressure mean when the lubricator is installed on my air line?
It is the highest pressure the aluminium body and polycarbonate bowl can safely contain. Your regulator and relief valve must keep line pressure at or below 150 psi during all operating conditions.
