Driven Oxygen Boosters Model 26968 For life support depend on Haskel Oxygen Boosters Filling aircraft on-board 02 cylinders for commercial, military and private fleets. Transferring 02 into various high pressure receivers for deep ocean diving support, commercial or military. These are just two examples of the uses for Model 26968 oxygen boosters that have provided cost savings and increased safety for many years. 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 to maximum pressure. Conventional industrial, shipboard or contractor type compressed air sources are normally used for power. All motive power and controls are completely pneumatic with no electrical connections required. The basic booster is two-stage, rated for continuous duty compression ratios of over 15:1, intermittent to 40:1. 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, permitting unattended operation. Features • Drive is a low friction, slow speed cycling air cylinder, designed for continuous duty without airline 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° 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.
