- Aluminium body and bowl resist corrosion in harsh environments
- Sight dome and gauge allow instant oil-level monitoring
SPEEDAIRE 3/8 in Air Line Lubricator
The SPEEDAIRE 4ZL90 is a micro-mist lubricator designed for compressed-air systems that require consistent oil delivery. Its 3/8 in NPT female inlet suits standard-duty pneumatic lines in workshops and light industrial settings. Builders needing higher flow capacity or a larger port size will need a different model.
Micro-mist design with aluminium bowl
The micro-mist mechanism creates a fine aerosol that travels longer distances through distribution piping than coarse-mist alternatives. An aluminium bowl and body resist corrosion while the integrated sight dome and gauge let operators confirm oil level and flow at a glance. Screwdriver adjustment allows precise feed-rate tuning without special tools.
250 psi and 175 °F operating envelope
Maximum operating pressure is 250 psi and maximum temperature is 175 °F, so the unit must not be installed downstream of compressors or aftercoolers that exceed either limit. Rated flow is 114 cfm; systems demanding higher continuous throughput will require a larger lubricator. California Proposition 65 warnings apply to chemicals present in the product.

Questions about this item
How often will the micro-mist lubricator bowl need refilling?
The aluminum bowl holds enough oil for extended runs; refill intervals depend on the 114 cfm flow rate and your tool consumption.
At 250 psi maximum pressure, which component reaches its limit first during continuous operation?
The 250 psi rating applies to the entire aluminum body; sustained use at that pressure keeps the micro-mist mechanism within its design envelope.
How much heat does the 3/8 in NPT lubricator add to the line when running all day at 175 °F?
The unit is rated to 175 °F ambient; it adds negligible heat because the micro-mist process relies on air expansion, not external power.
