Miniature filter-regulator for 1/4 in NPT systems
This SPEEDAIRE unit combines particulate filtration and pressure regulation in a miniature body designed for 1/4 in NPT female ports. It suits workshops and light industrial lines that need clean, regulated air at modest flow rates. Buyers needing higher flow or larger port sizes should look elsewhere.
150 psi rating with 14 cfm flow and manual drain
The zinc body handles a maximum operating pressure of 150 psi while delivering up to 14 cfm through a 5 micron polycarbonate bowl. Air travels left to right with a top-mounted reinforced nylon knob for pressure adjustment. No pressure gauge is included, so operators must supply their own monitoring.
Polycarbonate bowl and manual drain simplify
The transparent bowl lets technicians spot contamination at a glance, while the manual drain releases collected moisture without tools. Reinforced nylon adjustment knob resists wear from frequent tuning. California Proposition 65 warnings apply for cancer and reproductive harm.

Questions about this item
How do I install the 1/4 in NPT filter regulator and what step is often missed?
Connect the 1/4 in NPT female ports with thread sealant, orient the body so air flows left to right, and do not forget to tighten the polycarbonate bowl until the manual drain seats fully.
What maintenance will the 5 micron particulate filter need later?
Depressurise the line, unscrew the polycarbonate bowl, discard trapped contaminants, rinse or replace the 5 micron element, then reassemble and check the manual drain for leaks.
What limit appears first when running continuously at 14 cfm?
The 150 psi maximum operating pressure is the first hard limit; sustained flow at 14 cfm must stay at or below that pressure to avoid over-stressing the zinc body and reinforced nylon knob.
