Allegro Industries low- and high-pressure respirators and supplied air systems

December 12, 2014 - Offering a complete line of NIOSH-approved respirator masks, hoods, helmets, air-source equipment, and accessories, Allegro Industries has pioneered the concept of supplied air systems. Low-pressure systems are manufactured with a continuous-flow supplied-air mask, hood, helmet, or air shield in addition to a supplied air source and 50- or 100 feet of breathing air hose. These systems are good for one to three workers. Low- and high-pressure systems are available with a variety of useful accessories, including flow test kits, CO monitors, and airline cascade kits.

The Deluxe Supplied Air Shield/Helmet System for one or two workers provides all-in-one head, eye, face respirator protection against hazardous airborne contaminates and flying debris. The Economy Supplied Air Shield System is available in a low pressure or high pressure model and is perfect for use with grinding, chipping, spray painting and auto body repair. The visor is made of Nylon plastic, the lens is polycarbonate and the chin guard is polypropylene for added strength, while the shroud is cotton for comfort.  The Full Mask Supplied Air Respirator, available as a low-pressure or high pressure system, is made of silicone rubber for durability and will hold its shape even in extreme heat and cold.

Allegro’s family of Disposable Hoods offers a loose-fitting alternative to masks and are especially comfortable for bearded workers. Choose from the Maintenance Free Tyvek, Maintenance Free Saran, Double Bib Maintenance Free Tyvek, These Fully Disposable Hoods are designed with the down-tube integrated into the hood, so there’s no need for decontamination. Popular in dirty environments such as spray painting or asbestos abatement, their various coatings and designs protect workers against a broad range of chemicals, and their large, clear windows provide an expansive view. The Deluxe Tyvek Double Bib Hard Hat and the Tyvek Supplied Air Respirator Hood offer a reinforced down tube with swivel connection for added flexibility. All Allegro respirators incorporate a unique over-the-shoulder design to keep the air hose out of the way of work. Use the above hoods with a Low Pressure Flow Adaptor and/or with a High Pressure Controller. Other low-pressure NIOSH-approved supplied air respirators include the full-mask and half-mask styles, which are soft and pliable and offer continuous flow protection.

Low-Pressure one-worker systems offer a lightweight air source for a single worker. They are complete in one shipping carton and include the following: a comfortable NIOSH-approved full-mask, half-mask, or hood-style supplied air respirator; a 1/3 hp ambient air pump with the masks and a ¾ hp pump with the hood; and a 50- or a 100-foot breathing hose.

Two-Worker Systems offer a portable air source for two users. These systems include either two full-mask, half-mask, or hood-style supplied air respirators; a ¾ hp ambient air pump with the masks and a 1½ hp pump with the hoods, and a choice of a 50- or a 100-foot breathing air hose. The Three-Worker Systems provide three respirator users with three full-mask or half-mask supplied air respirators, a totally enclosed 1½ hp ambient air pump and a choice of a 50- or 100-foot breathing air hose.
