Description & Features

This Numatics FlexiBlok Series Air Line Piggyback Filter/Regulator combines filtration and pressure regulation in a single, modular unit. Featuring 1/4 inch ports, this unit delivers a flow rating of 40 SCFM.

The particulate filter includes a standard 5 micron element for removing water, dust, and debris from the air line. The regulator reduces supply pressure to the required working pressure. A manual drain simplifies maintenance. Constructed with a polycarbonate bowl, it withstands maximum inlet pressure up to 150 psi.

got a small air setup in the shop, is this one gonna keep up or is it kinda restrictive?
Answer by: Customer Support on Jan 29, 2026, 9:31 AM
For a 1/4 inch port filter and regulator combo, 40 SCFM is a solid flow rating and it is meant to handle typical small pneumatic circuits without choking them down. It also uses a 5 micron particulate element to pull out water, dust, and debris while the regulator knocks supply pressure down to your working pressure.

what's the max pressure this thing can handle before you start runnin into trouble with that plastic bowl?
Answer by: Customer Support on Feb 11, 2026, 3:06 PM
Polycarbonate bowls on this unit are rated up to 150 psi inlet pressure. If your system runs higher than that, there is an optional metal bowl available that pushes the limit up to 200 psi. Worth knowing before you plumb it in.
