Allegro Half Mask Low Pressure Supplied Air Respirator
Complete Half Mask Systems offer portable, light-weight air sources for one, two, or three workers. They are offered with one, two, or three comfortable half mask supplied air respirators, a ¼ hp ambient air pump, ¾ hp pump or 1½ hp pump, and 50 or 100 foot breathing air hose.
Ambient Air Breathing Pumps are designed to be used outside the contaminated work environment to bring clean, breathable air into a supplied air respirator or hood. They offer a low cost portable air source when a compressor is not available. They are portable and oil-less, producing no carbon monoxide, oil vapor or oil mist, thus eliminating the need for carbon monoxide monitoring and alarm systems. All pumps come fully assembled including all filters, fittings, and couplers.
