3M 7100150941 Papr Filter Latch Assembly Latch Mount

Product Description

The 3M 7100150941 is a latch-mounted, intrinsically safe filter latch assembly designed for use with powered air-purifying respirator (PAPR) systems in the TR-800 series. This replacement component secures the filter element to the PAPR blower unit using a latch-mount interface, maintaining a reliable seal between the filter and the airflow path. Weighing 3.67 pounds and measuring 10.63 inches in length, 9.25 inches in width, and 7.38 inches in height, it is built for field replacement by industrial hygienists, safety professionals, and trained technicians responsible for maintaining respiratory protection equipment in hazardous environments.

This assembly is intended for use in environments where intrinsically safe equipment is required, such as facilities with flammable gases, vapors, or combustible dust classifications. It fits the TR-800 series PAPR system and is the correct replacement latch assembly when the original component is damaged, worn, or no longer maintains a proper filter connection. Installation is typically performed as part of a scheduled respirator maintenance cycle or following a field inspection that identifies a compromised latch mechanism.

Compatibility

Designed as an OEM-style replacement filter latch assembly for the 3M TR-800 series powered air-purifying respirator (PAPR) blower units.

Installation Notes

Installation should be performed by a qualified safety technician or industrial hygienist familiar with PAPR system maintenance procedures. Before replacing the latch assembly, ensure the PAPR unit is powered off and the battery is disconnected. Verify that the replacement assembly seats fully and the latch engages correctly before returning the unit to service. Follow the applicable OSHA respiratory protection program requirements and the manufacturer service documentation when performing component-level maintenance.
