Haskel Air-Driven Oxygen Booster

MODEL 26968

FOR LIFE SUPPORT DEPEND ON HASKEL OXYGEN BOOSTERS

Filling aircraft on-board oxygen cylinders for commercial, military and private fleets. Transferring oxygen 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.

The 26968 gas booster system will boost oxygen 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 gas booster is two-stage, rated for continuous compression ratios of over 15:1, intermittent to 40:1.

A pneumatic control package monitors both inlet cylinder pressure and outlet receiver pressure continuously, stopping the booster automatically when desired outlet or minimum inlet pressure is reached, permitting unattended operation.

Key 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 compensate for wear, are 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 an interstage cooler, resulting in high-pressure cylinder temperatures well below the limits needed for the 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 directly in proportion to the gas supply pressure.

Performance

Outlet stall (maximum gas outlet pressure is: air drive psi x 30 plus 2 x gas inlet psi)
Interstage stall (maximum gas inlet pressure is: air drive psi x 15 if outlet pressure exceeds air drive psi x 30. If it does not, maximum gas inlet pressure is air drive psi x 30)
If less air flow is available, outlet gas rates will decrease approximately in proportion
