Description
The Allegro 9821 A-750 Breathing Air Pump is a compact and lightweight air source designed to deliver breathable air in situations where traditional compressed cylinders are impractical. The oil-less, rotary vane pump produces no oil vapor or carbon monoxide, helping provide safer air for respirator users without the need for integrated CO monitoring equipment. It is suitable for use in painting booths, cleaning, sanding, chemical handling and other industrial applications requiring a reliable supplied-air source.
Built on a rigid metal base and housing with brass and galvanized steel plumbing, the unit includes a quick-connect OBAC fitting, adjustable brass pressure relief valve, and a pressure gauge so air delivery can be precisely controlled. With a 3/4 HP motor capable of operating on 115/230 V AC (single phase), the A-750 delivers up to 10 CFM of air at 60 Hz (8 CFM at 50 Hz) with a working pressure range of 2–12 psi (15 psi max).
The pump’s 50 µm inlet filter and 0.3 µm HEPA exhaust filter help maintain air cleanliness, and its portable design with a steel handle makes it easy to transport and position where needed. The maximum recommended airline length from the pump to the respirator is 100 feet (sold separately), giving flexibility for various jobsite layouts.
