Allegro Industries' Deluxe Supplied Air Shield/Helmet System for one or two workers provides all-in-one head, eye, face respirator protection against hazardous airborn contaminates and flying debris. The Low Pressure 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. The company's 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, various coatings and designs protect workers against a broad range of chemicals, and 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.
