Provides portable high pressure air for refilling your precharged airgun while at home or in the field. The high pressure system provides ample fills on any size airgun cylinder, and reduces the frequency of having to travel to dive shops for a refill. This unit comes complete with the cylinder, valve and hose, making it ready to use with any standard 1/8" BSP adaptor which comes standard with most airguns. New to this cylinder is the 4500psi certified, simple to use valve. This valve allows precise control of the fill rate, and utilizes a design that restricts the flow rate while filling an airgun, but has no restriction while refilling the cylinder. Included is a quality 2-inch, Stainless-Steel gauge that is oil filled and reads in both PSI and BAR measurements. The DIN style valve comes complete with a 1 Meter long Zero-Kink hose that can be tied in a knot without kinking, and includes an adapter to fit the valve, making this unit compatible with both hose and DIN style fills.
