The ALLEGRO 9820-HP is a filtration panel accessory designed for use with PAPR (Powered Air-Purifying Respirator) and SAR (Supplied-Air Respirator) headgear systems. Filtration panels serve as a critical component in respiratory protection, helping to maintain air quality delivered to the wearer by capturing particulates and contaminants before they reach the breathing zone. This part is installed and serviced by safety professionals, industrial hygienists, and certified respirator fit-test technicians working in environments requiring continuous respiratory protection.
Filtration panels of this type are used in industrial, construction, pharmaceutical, and hazardous materials handling environments where workers require head-mounted respiratory protection. They are integrated into compatible PAPR and SAR hood assemblies to extend service life and maintain filtration performance. Regular replacement of filtration panels is standard practice under most respiratory protection programs governed by OSHA 29 CFR 1910.134.
The 9820-HP is designated for use with Filtration Panels series-compatible PAPR and SAR headgear systems as specified in the input data. Confirm compatibility with your specific hood assembly before installation.
Filtration panel replacement should be performed by a qualified person following the respirator manufacturer instructions and the facility respiratory protection program. Ensure the PAPR or SAR unit is fully powered down and disconnected from the air supply before servicing any headgear components. Inspect the hood assembly for damage or seal degradation during each panel change. Follow applicable OSHA respiratory protection standards and local safety regulations when servicing respiratory protection equipment.
