Base Plate and Retainer for P2 Pre-Filter

The base plate and retainer is designed to hold a P2 pre-filter in place on respiratory protection equipment. It ensures the filter remains correctly positioned during wear, maintaining a secure seal between the mask and the filter cartridge. This component is essential for the proper function of the filtration system, as it prevents movement or dislodgement of the filter during use. It is sold as a pair to support both sides of the mask assembly.

By securing the pre-filter, this accessory helps reduce the intake of airborne particulates such as dust, mist, and fumes commonly encountered in industrial, trade, and maintenance environments. Effective filtration depends on the filter remaining intact and properly seated, which this component supports. If the filter becomes saturated or compromised, contaminants may bypass the seal and be detected by smell, taste, or irritation, indicating the need for immediate replacement. The retainer does not filter contaminants itself but enables the filter to perform as intended.

It is intended for use with specific half face masks models 5500 and 7700, as well as the full face mask model 7600, when paired with a P2 pre-filter. The assembly is certified to meet the requirements of AS/NZS 1716:2012 for respiratory protective devices. Users should inspect the retainer and filter before each use for signs of damage, wear, or improper fit. Replacement is advised if any component shows cracking, deformation, or loss of tension that could affect the seal.
