Our NIOSH-approved Maintenance Free Tyvek Hood is so unique, it’s patented. This hood is designed with the breathing or down tube and head suspension completely integrated so that the hood assembly is constructed into a one-piece instead of the standard three-piece assembly. This eliminates the need for decontamination of the breathing tube or replacement parts, because the entire hood assembly is disposed of after use. Because the down tube is integrated into the hood, it is maintenance free and completely disposable. Offered in poly-coated DuPont Tyvek, it is flexible, splash resistant and seals in the air flow. The breathing tube incorporates a multi-layer sound dampening system made of foam extending up inside the hood that prevents the tube from being crushed or twisted during use. It allows the system to meet stringent NIOSH requirements for sound levels inside a hood. The disposable hood brings air down across the lens which minimizes fogging and brings air to the breathing area. A large viewing window provides a wide field of vision and its generous size makes it perfect for workers with beards or goggles. Its large bib provides splash protection and allows it to be tucked into a suit where it directs air to the body. The disposable one-piece suspension offers easy adjustment with a hook and loop closure and an absorbent foam headband. NIOSH approved. The hood comes with Allegro’s Low Pressure Flow Adapter, which allows the hood to connect to an ambient air pump or any low pressure air source.
