Fully Disposable Tyvek Hood
Maintenance Free Tyvek Hood
Allegro's NIOSH-approved Fully Disposable 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 3-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 multilayer sound dampening system made up 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 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 velcro closure and an absorbent foam headband.

LP Allegroair Airline Cooling System
LP Allegroair Airline Cooling System

This is a perfect, low cost and portable means of cooling breathing air while keeping workers comfortable and productive for hours. The system is capable of reducing the air temperature from 180°F to as low as 50°F. The cooling system is connected to the Ambient Air Pump through a 5' long inlet supply airline using a heavy duty "Chicago Style" coupler. Air flowing through the FDA Grade PVC temperature cooling coil inside the 70 quart cooler reduces the air temperature by having ice poured onto and around the coil. Coils are separated to allow ice to surround hose. The outlet air is filtered at the end of the coil line by a 5 micron particulate air filter, which removes condensation that may build up in the hose. An Adjustable Relief Valve allows the user to adjust the air flow. Single outlet Coupler can adapt to 3-Worker Manifold and can be used with up to 3- Worker Ambient Air Pump. Transportation is made easy with durable wheels and a locking telescoping pull handle.
Dimensions: 20" w x 21" D x 24" H, 28 lbs. without ice
