Cascade Systems
A cascade system can speed up refills considerably.
Eg. Our CS9 compressor will fill 4 SCUBA tanks in about 50 minutes.
A cascade system can fill them in about 5 minutes!
We can mount your cylinders on your truck or trailer, against a wall,
or on a stand (see below).
The price of the storage bottle includes nut & nipple, stainless steal tubing, and valve.
We carry 4,500 PSI, 5,000 PSI, and 6,000 PSI cylinders.
We can also supply you with a regulator; a fill hose, and an adapter to attach to your SCBA, SCUBA, or paintball tank.
Technical Information
These are UN Pressure Receptacles. These cylinders meet or exceed the DOT standards and are DOT qualified. The biggest advantage is they only need to be hydro tested every 10 years.
