Allegro Tyvek Maintenance Free Poly-coated Hood with Flow Control Valve 9911-CV

NIOSH approved Maintenance Free Tyvek Hood is so unique, it’s patented! This hood is designed with the breathing/downtube and head suspension completely integrated so that the hood assembly is a one-piece construction instead of the standard three-piece assembly. This eliminates the need for decontamination of the downtube or replacement parts because the entire hood assembly is disposed of after use. Because the downtube 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 airflow. The downtube 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. While also bringing air into the hood to the breathing area, it allows for minimal lens fogging increasing productivity. 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.
