Gas Flow Restrictors
Porous metal flow restrictors are used in applications that require anti-clogging or laminar flow. Thousands of flow paths through the porous metal prevent the restrictor from clogging if a large particle makes it into the gas stream. This thousand-pore structure ensures laminar flow in even the most intense conditions and eliminates turbulent flow on the outlet. Restrictors are available in a wide variety of alloys and hardware configurations to suit your process.

Product Specs
| Compatible Flow Rates |
Mott can tune restrictors to virtually an infinite number of flow rates. Consult with a Mott representative to procure a flow restrictor that’s right for your process conditions. |
|---|---|
| Flow Accuracy |
Mott restrictors are typically +/- 7.5% of the specified flow rate. Ultra-high accuracy restrictors can be manufactured upon request with accuracies down to 1%. For ultra-low flow rates, broader accuracy ranges may be required. |
