The Model 26968 Oxygen Booster Unit is designed for use of filling Oxygen cylinders for use in commercial and military scuba diving applications, has come to realize broader applications in the transferring of oxygen into various high pressure receivers many industrial applications.
This model will pump from high or medium pressure sources and will also function effectively to collect and transfer the gas from partially depleted supply cylinders to “top off” other cylinders in order to maximize pressure.
Conventional compressed air sources are used for all power and control. No electrical connections are required.
The basic booster is two-stage. A pneumatic control package continually monitors both inlet cylinder pressure and outlet receiver pressure, stopping the booster automatically when desired outlet or minimum inlet pressure is reached, thus permitting unattended operation.
Drive is low friction, slow speed cycling air cylinder, designed for continuous duty without air line lubrication. Vented distance pieces insure hydrocarbon-free gas section operation. High pressure oxygen seals are wear compensating, immune to sudden failure and operate completely non-lube, oil free.
Very cold air (as low as -20 degrees F) is a natural by-product from the air powered drive exhaust. This frigid exhaust air is channeled through a system of cooling jackets and interstage cooler, resulting in high pressure cylinder temperatures well below limits needed for long life of critical parts.
Inlet gas supply pressure acts directly through the opposed piston construction to assist the air drive during the compression stroke, conserving power required by the drive in direct proportion to the gas supply pressure.
Air driven, balanced opposed piston type, two stage.
