Description
The Allegro 9909‑RD Deluxe Double Bib Hard Hat Hood w/ Ratchet is a durable and protective respiratory hood assembly made from poly‑coated DuPont® Tyvek® that delivers clean, supplied breathing air while offering enhanced comfort and protection in industrial environments. Its double bib style increases coverage by allowing the inner bib to be tucked into protective clothing, helping shield the neck and shoulders from contaminants. The hood’s generous internal space accommodates a hard hat and other PPE without restricting movement or view.
A key feature of this model is the ratchet adjustment suspension system, which lets users fine‑tune the fit quickly and securely, improving comfort during extended use. Integrated with a reinforced flexible downtube and swivel connection, the assembly helps reduce hose drag and fatigue. The split air channel design directs airflow around the temple area to enhance comfort and minimize lens fogging.
This hood is intended for use with low‑pressure supplied‑air respirator systems and is typically paired with an Allegro LP flow adapter and approved airline hoses. Its robust yet lightweight construction makes it suitable for a wide range of industrial applications where respiratory protection with headgear compatibility is required.
