Martech Services Company’s Quality Air Breathing System is designed to operate from an existing compressed-air supply near the point of use. The unit combines four-stage filtration with an onboard carbon-monoxide monitor. According to the company, the monitor continuously checks filtered air against OSHA Grade D breathing-air requirements.

Configurations are available for painters, blasters and welders and may include hoods, masks and hoses. Systems can support two or more users at the same time, depending on configuration. Accessories can heat or cool the supplied air for worker comfort. Martech said each system carries a one-year warranty and is supported through a toll-free sales and service line.
