Allegro 9901 Full Facepiece Mask Assembly Supplied Air

Product Description

The ALLEGRO 9901 is a full facepiece mask assembly designed for use with low-pressure supplied-air respirator systems. Built from silicone, the facepiece provides a durable, face-conforming seal suited to extended wear in environments requiring continuous clean-air delivery. At 2 pounds, the assembly balances protection with manageable weight during use. Licensed safety professionals, industrial hygienists, and trained tradespeople install and fit-test supplied-air respirators in compliance with OSHA respiratory protection standards. This component is intended to restore or replace the mask portion of a compatible Allegro supplied-air kit.

This facepiece assembly is used in industrial and commercial settings where supplied-air respirators are required - including confined space entry, painting operations, chemical handling, and other environments where ambient air is not safe to breathe. It is compatible with Allegro low-pressure supplied-air respirator kits and is suited for both fixed-position and mobile supplied-air applications. The silicone construction performs across a range of temperatures and resists degradation from common industrial contaminants.
