Filtered Orifice Restrictors

Avoid clogged flow lines with filtered orifice restrictors from Coast Pneumatics.

Filtered orifice restrictors are compact devices with precision-drilled holes and protective filtration screens that control flow streams, dropping pressure from upstream to downstream processes in pneumatic control circuits. The protective filter usually is encased within a precision-molded polysulfone housing.

Create a reliable method to produce a predictable, repeatable flow rate of liquid, gas or air at your process by choosing a specific diameter filtered orifice restrictor. Filtered orifice restrictors are available in eleven color-coded sizes, from 0.004" to 0.040". The orifices are molded with precision from polysulfone and can meet flow tolerances of +/- 4 percent.
