  • Polycarbonate bowl with steel guard resists impact damage
  • Sight dome and gauge let you monitor oil level

3/8 in NPT air line lubricator

The SPEEDAIRE 4ZL75 is an intermediate-duty mist lubricator built for 3/8 in NPT compressed-air lines. It delivers a maximum flow of 75 cfm at up to 150 psi and operates up to 125 °F. The aluminum body and polycarbonate bowl with steel guard suit workshop and light-industrial pneumatic systems.

Included sight dome and gauge simplify daily checks

A clear sight dome lets operators confirm oil mist at a glance while the integrated sight gauge shows bowl level without removal. Adjustment is via a screwdriver-actuated PE mechanism and flow direction is fixed left to right. No external power or electronic controls are required.

Verify port size pressure and chemical restrictions

Confirm the existing circuit uses 3/8 in NPT threads and that system pressure never exceeds 150 psi. The unit contains substances listed under California Proposition 65 for cancer and reproductive harm, so review local regulations before installation in affected jurisdictions.

Questions about this item

How often should I refill the polycarbonate bowl on the SPEEDAIRE 4ZL75 lubricator?

Refill frequency depends on your air consumption; the sight dome and gauge let you see the oil level at a glance so you can top up before it runs dry.

Will the 75 cfm flow rating become a bottleneck if I run multiple tools at once?

The unit is rated for a maximum flow of 75 cfm at 150 psi; exceeding that flow will starve downstream tools of lubricated air.

Does the aluminum body stay cool enough during continuous shop use?

With a maximum operating temperature of 125 degrees F the body dissipates heat effectively, but ambient temperatures above that limit can degrade the polycarbonate bowl and seals.
