Allegro 9221-01A Sar Hood 50 Ft Hose Blower Flow Indicator

Product Description

The ALLEGRO 9221-01A is a supplied-air respirator (SAR) hood assembly designed for industrial respiratory protection in environments where ambient air quality is unsafe to breathe. The system includes a Tyvek hood with a clear hood window, a 50-foot breathing air supply hose, a breathing air blower, and a flow indicator. The flow indicator provides a visual confirmation that adequate airflow is reaching the user. Tyvek construction keeps the hood lightweight while offering a barrier against particulates. This assembly is intended for use by safety and industrial hygiene professionals in manufacturing, remediation, and chemical handling applications where a full breathing air supply is required.

The 9221-01A is suited for industrial SAR applications including confined space entry support, spray finishing, abrasive blasting observation zones, and hazardous material handling. The 50-foot hose gives the wearer meaningful range from the air supply source without compromising airflow delivery. The hood-style headgear provides full-head coverage without the fit-testing requirements associated with tight-fitting respirators, making it practical for a wider range of face profiles and for extended-wear scenarios on job sites.

Key Features

• Complete SAR hood assembly — hose, blower, flow indicator, and Tyvek hood included
• 50-foot breathing air supply hose provides extended range from air source
• Flow indicator gives visual confirmation of active airflow to the hood
• Tyvek hood construction offers particulate barrier with low weight
• Clear hood window maintains sightlines during use
• Non-adjustable, foam-suspension hood design accommodates a wide range of users without fit testing

Compatibility

Designed for use with SAR-compatible breathing air supply systems in industrial settings. Specific system compatibility is SAR type. Verify that the breathing air source meets applicable compressed breathing air standards before connecting this assembly.

Installation Notes

SAR hood systems are typically deployed by industrial hygienists, safety officers, or trained confined space entry crews following OSHA 29 CFR 1910.134 respiratory protection program requirements. Before use, confirm the air supply source is rated for breathing air quality and that the flow indicator shows positive airflow. Inspect the hose for kinks, cracks, or compromised fittings prior to each use. Do not connect this assembly to non-breathing-air compressed air sources such as standard shop air lines without verified air quality testing and appropriate filtration.
