3M 7100153811 Belt Mounted Papr Motor Blower Unit

Product Description

The 3M 7100153811 is a belt-mounted powered air-purifying respirator (PAPR) motor blower unit designed for use with the 3M Series TR-300 respiratory protection system. The unit draws ambient air through a connected filter and delivers a continuous flow of filtered air to the headgear, reducing breathing resistance for the wearer. It is powered by a lithium-ion battery and mounts securely to a belt for hands-free operation during extended tasks. Licensed industrial hygienists, safety professionals, and qualified technicians performing maintenance or equipment setup work with this type of unit. Key physical dimensions are 10.63 inches in length, 9.25 inches in width, and 7.38 inches in height, with a weight of 6.38 pounds.

This PAPR blower unit is intended for use in environments where workers require continuous filtered airflow protection, such as manufacturing, construction, painting, welding, or other industrial settings with airborne particulate or chemical hazards. It is designed for use as part of the TR-300 series PAPR system. The belt-mount configuration distributes weight at the waist, making it practical for sustained wear during shift-length tasks. Replacement of this unit is typically performed by a safety equipment technician or trained industrial hygiene personnel.
