Yes. The Allegro 9210-02 is a complete, portable low-pressure supplied-air system built to feed two workers simultaneously. It bundles everything needed in one kit: two full-face supplied-air respirators, a ¾ HP oil-less ambient air pump, and two 100-foot (34.4 m) breathing air hoses. The pump draws air from a clean, breathable area and delivers a continuous flow of 0–10 CFM (0–16.99 m³/hr) — enough capacity to serve both masks — so neither worker relies on cartridges or a heavy air bottle. It's a strong fit for two-person tasks like abrasive blasting, spray painting, tank/vessel work, and general industrial jobs where a steady supply of clean air is needed and the pump can be stationed in fresh air.

The Allegro 9210-02 includes two full-mask supplied-air respirators, a ¾ HP oil-less rotary-vane ambient air pump, and two 100-foot (34.4 m) breathing air hoses. Pump specs: 0–10 CFM (0–16.99 m³/hr) output, working pressure 2–12 psi (15 psi max), a 1½" steel-housing pressure gauge, a 40-micron inlet filter, and a 0.3-micron HEPA exhaust filter. The motor is ¾ HP, UL Listed, runs on 115V/230V AC single phase, and draws 8.3 A. Each hose is PVC with reinforced braided polyester yarn, rated −20°F to 150°F and 185 psi max. It ships with free shipping from Industrial Safety Products.

The Allegro 9210-02 uses a ¾ HP oil-less, rotary-vane ambient air pump with carbon vanes. It pulls in surrounding air, filters it (a 40-micron bronze/steel inlet filter plus a 0.3-micron HEPA exhaust filter), and pushes a continuous, low-pressure flow of 0–10 CFM through two 100-foot hoses to the two full-face masks. Because it's oil-less, no oil vapor can enter the air stream. Working pressure runs 2–12 psi (15 psi max), monitored on a 1½" gauge. The pump must be placed where the air it draws is clean and breathable.

No. Ambient air pump systems like the Allegro 9210-02 supply air drawn from the surrounding environment, so they are intended for atmospheres that are not immediately dangerous to life or health (IDLH) and not oxygen-deficient. The pump must be positioned in a clean, breathable-air area, away from the contaminant source. For IDLH conditions, confined-space entry with unknown hazards, or oxygen-deficient spaces, a self-contained breathing apparatus (SCBA) or a pressure-demand airline system with escape provisions is required instead. Always follow OSHA 29 CFR 1910.134 and your site's respiratory protection program.

Yes. Allegro states that its full-mask low-pressure supplied-air respirator (the mask used in the 9210-02 system) is NIOSH approved. The respirator is a continuous-flow supplied-air design fed by the system's ambient air pump. As with any supplied-air respirator, it must be used as a complete NIOSH-approved assembly — approved mask, hose, and air-source components together — to remain within its approval.

The Allegro 9210-02 full masks are made of durable silicone rubber that is hypoallergenic and chemical/Ozone resistant, with a replaceable polycarbonate lens for a wide, clear field of view. Each mask includes a removable hairnet and a down tube with a 90-degree elbow so the hose can be routed over the shoulder, connected via an OBAC quick-connect plug. The masks are designed as one-size-fits-most.

The Allegro 9210-02 comes with two 100-foot (34.4 m) breathing air hoses — one per worker — so each worker can operate up to about 100 feet from the pump while it stays in clean air. The hoses are polyvinyl chloride reinforced with braided polyester yarn, rated for −20°F to 150°F (−28.8°C to 65.5°C) and a maximum pressure of 185 psi at 70°F. A shorter 50-foot two-worker version is offered as the Allegro 9200-02; the 9210-02 is the 100-foot configuration.

The Allegro 9210-02 uses a ¾ HP UL Listed motor that runs on 115V/230V AC single phase and draws 8.3 A. That higher amperage (versus the ¼ HP one-worker version's 5.5 A) reflects the larger pump needed to feed two masks with a combined 0–10 CFM. Confirm the circuit can supply 8.3 A continuously before running it on a shared job-site or shop outlet. The one-worker version uses a ¼ HP motor (5.5 A), and the three-worker version a 1½ HP motor (16 A).

The Allegro 9210-02 gives two workers an unlimited, continuous flow of fresh air pumped from a clean area, unlike a cartridge/APR respirator that only filters the surrounding contaminated air and has limited cartridge life. Compared with an SCBA — where each worker carries a heavy, time-limited air cylinder — the 9210-02 keeps weight off the workers and won't run out mid-task, since the air comes from the ¾ HP pump through two 100-foot hoses. The trade-off is mobility (each worker is tethered to a hose) and the requirement that the pump sit in breathable air, so it's not for IDLH or oxygen-deficient spaces.

The Allegro 9210 series scales by number of workers, all using 100-foot (34.4 m) hoses. The 9210-01 is a one-worker kit with one mask and a ¼ HP pump (0–5 CFM, 5.5 A). The 9210-02 is a two-worker kit with two masks and two hoses driven by a ¾ HP pump (0–10 CFM, 8.3 A). The 9210-03 is a three-worker kit with three masks and three hoses driven by a 1½ HP pump (0–20 CFM, 16 A). All share the same mask (silicone, polycarbonate lens, OBAC quick-connect), oil-less rotary-vane pump design, HEPA exhaust filter, and PVC braided hose. Choose the 9210-02 when two workers need supplied air at once.

The Allegro 9210-02 Two-Worker Full Mask System with two 100' hoses is available at Industrial Safety Products (industrialsafetyproducts.com), which offers free shipping. It's the complete two-worker kit (SKU 9210-02) with two full-face respirators, a ¾ HP ambient air pump, and two 100-foot breathing air hoses included.
