GENERAL FILTER SYSTEM DESCRIPTION

(Refer to Figure No.1)

Air entering the MST Breathing Air Panel at the inlet (A) is usually contaminated with oil, water, dirt, rust, scale and gaseous Hydrocarbons. As the air passes through the First Stage (B) of the MST

Prefilter, particulate matter is trapped and retained down to 0.3 microns. The air then enters the

Second Stage (C) of the Prefilter which coalesces liquid contaminates down to 0.75 microns with an efficiency rating of 99.97% (meets Underwriters Laboratories Specification UL 586 for High

Efficiency, Particulate, Air Filter Units). The liquid contaminates are trapped in the lower chamber of the prefilter and expelled out through the Automatic Float Drain (D). The Third and Fourth

Stages (E & F) contain a deep bed of odor absorbing activated charcoal which collects various gaseous Hydrocarbons (such as oil fumes, benzene, etc.). The air is then passed through the Air

Pressure Regulator (G), which is used to adjust the air pressure going to the respirator. A sample of the filtered air is taken at (H) and passed through the Carbon Monoxide Monitor (I). The Carbon

Monoxide Monitor continuously checks the carbon monoxide levels per OSHA/CSA requirements and digitally displays the amount present in PPM, (parts per million). An audible alarm/strobe will alert operators if levels of carbon monoxide exceed OSHA/CSA requirements.
