Allegro Industries manufactures an entire line of fully disposable SAR hoods. Designed with the breathing down tube and head suspension completely integrated,productsthese hoods are constructed into a one-piece assembly instead of the standard three-piece construction. This design eliminates the need for decontamination of the breathing tube or replacement parts by allowing the entire hood assembly to be disposed of after contamination.
