Allegro NV20-31 Papr Sar Headgear Nova 2000

Product Description

The ALLEGRO NV20-31 is a replacement PAPR and SAR headgear component designed for use with the Nova 2000 powered air-purifying respirator system. This headgear assembly secures the respiratory unit to the wearer's head, maintaining proper positioning of the breathing zone during operation. It serves as a direct-fit accessory for the Nova 2000 series and is the type of component replaced during routine maintenance or after wear that compromises fit integrity. Industrial hygienists, safety officers, and technicians managing respiratory protection programs are the typical installers of this part.

This headgear is suited for environments where PAPR or supplied-air respirator protection is required, including industrial facilities, chemical handling areas, confined space entry, and hazardous material operations. It is used in applications where workers need continuous positive-pressure air delivery and a secure, adjustable head fit. Replacement during scheduled maintenance intervals helps ensure the respiratory protection program remains in compliance with applicable occupational health and safety standards.

Installation Notes

Installation of PAPR and SAR headgear components should be performed by a qualified safety professional or technician familiar with respiratory protection program requirements. Ensure the powered air unit is fully powered down and disconnected from the air supply before replacing headgear components. Follow the manufacturer's fit and adjustment instructions to confirm an adequate seal and secure fit prior to returning the unit to service. Replacement and maintenance practices should align with OSHA 29 CFR 1910.134 or applicable regulatory standards governing respiratory protection programs.
