DSI Hyperbaric Fire Extinguisher use one Aluminium Cylinder rather than the old-style extinguishers of the past, which use two cylinders.

The extinguishers are charged up to 100 Bar with suitable chamber gas - either Air or Helium Mix.

When the fire extinguisher is required the safety pin needs to be removed and the foam is expelled when the handle is pressed. Activation is instant which produces a jet of non-toxic foam mixture. Both fire extinguishers can be used continuously or intermittently.

The DSI Hyperbaric Fire Extinguisher is supplied with a mounting bracket and the nozzle is held at the side with a Velcro retainer.

The Extinguishers are easily maintained and charged using the instructions labels located on the outside of the cylinder.
