Modern Safety Techniques

Purification & Filtration Systems
Supplied air respirators are used to provide air to workers in contaminated atmospheres found in paint spraying, sand blasting, asbestos abatement and other applications. They are usually supplied by oil-lubricated air compressors. Contaminants such as oil, rust, water, dirt, scale and deadly carbon monoxide gas can find their way into the intake of the compressor, or be produced by the compressor itself, turning a protective breathing apparatus into a hazardous accessory. Even oil-less type compressors can intake carbon monoxide and other contaminants.
Chemicals found in various paints and other adhesives and solvents require the use of supplied air respirators. In many instances, the use of cartridge type negative pressure respirators are no longer "permissible practices". (Consult NIOSH "Pocket Guide to Chemical Hazards" for information regarding the use of supplied air type respirators)
OSHA Regulations:
OSHA states in 29 CFR1910.134(d) that air quality for "Breathing air shall meet at least the requirements of the specification for Grade D breathing air as described in Compressed Gas Association Commodity Specification G-7.1-1989...Compressors shall be constructed and situated so as to avoid entray of contaminated into the system and suitable in-line air purifying sorbent beds and filters to further assure breathing air quality". The Compressed Gas Association (according to G-7.1-1989) lists the following maximum allowable contaminant levels in Grade D air:
Carbon Monoxide - 10 ppm
Carbon Dioxide - 1000 ppm
Condensed Hydrocarbons - 5 mg/m3

Don't Just Filter...Purify with MST's Low Temperature Catalyst to Remove CO

MST's unique LT CAT™ low temperature catalyst offers significant benefits over all other CO removal systems. Because MST uses a precious metal catalyst, the Respiratory Protector series Breathing Air Purification Systems convert CO to Carbon Dioxide without the limitations you find with every other CO removal system on the market today.
With MST's LT CAT catalyst, you don't need dryers. Other systems require very dry air to function (4% relative humidity) To get air this dry costs a lot of money, primarily for dessicant drying towers. When you factor in the cost of buying, operating and maintaining a dryer, clean air for your workers can become very expensive.
MST's Respiratory Protector systems are designed to operate continuously. All other CO removal systems require drying time to remove moisture from saturated dryers. Continous operation is possible with other companies' equipment, but they require "twin towers" to alternate operation while moisture is purged...more equipment, more complexity, more cost.
The ultra-dry air from all competitive systems is very uncomfortable for breathing. Respiratory Protector systems provide comfortably humid air for operators, avoiding overly dry nasal passages and discomfort.
At only 19 or 31 lbs., MST's portable Respiratory Protector systems are easy to get to the jobsite.
By eliminating dryers, our unique design removes more than half of the cost for most systems compared to other CO removal equipment, making CO removal affordable for any operation.

The four stages of air purification with MST purifiers are:
  1. Prefilter provides particulate removal
  2. Coalescing action for liquid contaminants
  3. Contains activated charcoal for removal of gaseous hydrocarbons, tastes and odors
  4. Contains unique low temperature catalyst for removal of carbon monoxide and other toxic gases

WARNING: MST's Air Purification Systems will not increase the oxygen content of an air supply and should not be used when air entering the system is oxygen deficient.

  8. Pressure regulator with indicating gauge for adjusting the correct pressure to operator's supplied air respirator system
  9. Quick disconnect included for easy connection to supplied air respirator system
  10. Carbon monoxide monitor, standard on all models
  11. Accessory port/indicator panel
These are the only truly portable, continuous-use CO removal systems available. Operators enjoy extra freedom while breathing cleaner, humidified air. In addition to weighing a mere 19 or 31 lbs., these Respiratory Protector systems come complete with CO monitor standard on all models. You can choose between the Model 5701 CO and oxygen monitor or the Model 5700 monitor with LCD display of CO in ppm.

Pocket Gas Monitors
Affordable compact toxic gas and oxygen detection monitors, designed for field use. They are accurate, rugged, reliable, water and EMI resistant and easy to read. Unlike models with digital displays, the MST monitors utilize a unique series of amber and red lights, along with audible alarms, to warn of increasingly dangerous levels of toxic gases or inadequate levels of oxygen.
In addition, the MST TS6500-CO, the TS6500-H2S and TS6500-O2 are virtually maintenance free, and guaranteed for one year. Once turned on, the monitors are designed to remain on for a full year with the only user maintenance being periodic calibration. As the monitors contain no field serviceable parts, they should be returned to MST after one year for service and a new one year warranty.
