Msa 81857 Airline Filter Scba 125 Psi

Product Description

The MSA 81857 is an airline filter designed for use with Self-Contained Breathing Apparatus (SCBA) systems. It filters the compressed air supply delivered to the breathing apparatus, helping maintain air quality at the point of connection. At a rated pressure of 125 psi, this filter is sized for standard airline supply pressures found in industrial and emergency response environments. Measuring 8.75 inches in height and 5.125 inches in width, the unit is built for inline installation on airline-fed SCBA setups. Installation is typically handled by safety equipment technicians or industrial hygienists familiar with SCBA system maintenance.

This airline filter is used in facilities and worksites where workers require a continuous supplied-air source through an SCBA or emergency escape breathing apparatus (EEBA) system. Common applications include confined space entry operations, hazmat response, industrial maintenance environments, and fire service training facilities. The filter installs between the airline supply source and the SCBA facepiece or manifold assembly to condition the incoming air stream.

Verify all fittings are properly rated for the system operating pressure before returning the system to service. Follow applicable OSHA and NIOSH guidelines for SCBA maintenance and inspection intervals.
