SUP777777 / 777777 PUMA 30-Minute Hooded SCBA Survivair®' PUMA™ The PUMA™ is the first NIOSH-certified, OSHA-compliant, hooded pressure demand SCBA designed to fit over beards and glasses. Not NFPA approved. This hood is made from coated Responder® multi-layer polypropylene material, one of the finest hazmat suit materials available. A flexible neoprene neck seal provides excellent protection against contaminants in IDLH atmospheres, even if the wearer has a beard, as long as it doesn't break the seal. The user can also wear non-safety glasses under the PUMA™. A sports strap on the temples is useful to keep glasses in place while donning. The easily removable exhalation valve allows fast, easy servicing. The factory-installed, removable silicone nose cup, available in three sizes, reduces fogging and CO2 build-up in hood. Configured unit includes a Panther-style first stage with plain whistle alarm, a 2,216 psig, 30-minute aluminum cylinder, without locking collar, and a PUMA hood with medium nose cup. We will contact you for nose cup size.
