MST's four-stage filtration system is standard on every portable model and provides extra protection for longer filter life and better filtering capabilities than most other comparable filtering systems. Pre-filter dual stage element removes particulate down to 0.3 microns and coalesces liquid down to 0.75 microns, at an efficiency rating of 99.97% (D.O.P.) A carbon monoxide monitor is available on every breathing air filter system we make to continuously monitor your breathing air for compliance with applicable standards. Monitors offer digital display, with both audio and visual alarms. All monitors utilize an electrochemical sensor to measure CO levels. The MST Breathing Air Panel Series can be supplied with or without carbon monoxide monitors, depending on end user's specific situation. This option is available on request.
