455 Balanced Regulator

Body: 

455 Balanced SS Regulator

455 Balanced Regulator

The 455 Balanced regulator, P/N 505-455, sets a milestone in surface supplied breathing performance and is also compatible with all Kirby Morgan Helmets and BandMasks® that feature the SuperFlow® 350 or 450 regulators.

The 455 Balanced regulator is a downstream balanced poppet design, and is featured on the new KM 97 Helmet. Like the widely used SuperFlow® 350, the 455 Balanced has a multi turn bias adjustment allowing the diver to compensate for variations in supply pressure and changes in physical attitude.

The regulator body is made of 316 stainless steel, as are all its other metal components. The 455 Balanced regulator is designed and engineered to be rugged, long lasting and easy to disassemble for simple, fast, cleaning and servicing.
