Allegro 9920 Constant Flow Respirator

The Allegro 9920 is a constant-flow airline respirator designed for workers who require a continuous supply of breathable air at 12 psi. It includes a facepiece, breathing tube, low-pressure flow adaptor, support belt, half mask and universal headgear for immediate use.

Sustained airflow at 12 psi

The system delivers a steady stream of air at 12 psi to maintain positive pressure inside the facepiece during extended shifts. The constant-flow design prevents pressure fluctuations that can occur with demand valves, and the low-pressure adaptor regulates supply from the airline source. The support belt distributes hose weight to reduce fatigue over long periods.
