Sundstrom SR500 EX Powered Respirator

The Sundstrom SR500 EX is an explosion-proof powered respirator fan unit, designed for use in potentially explosive atmospheres. Engineered for reliability and safety, it delivers filtered air through a breathing hose to a compatible headtop, creating positive pressure that prevents contaminants from entering the breathing zone. Ideal for demanding environments where filter respirators are insufficient or unsuitable for prolonged use.
