helium balloon gas recovery high pressure helium compressor 25Mpa
Advantages：
Our compressors withstand the stress of modern, continuous duty applications in the most demanding environments.
Dependable Performance: suited for continuous operation, due to their rugged design and corrosion resistant intermediate filter and cooler assemblies.
State-of-the-Art Design: balanced moving parts in the drive gear and connecting rods allows for low vibration and balanced rod loads. Interstage coolers, finned after cooler, finned cylinders, finned aluminium heads, and fan-bladed flywheel produce cooler operating and discharge temperatures.
Top Graded Materials: cast iron cylinders for long life; ductile iron counterbalanced crankshaft with large diameter throw for low bearing loads, high strength and increased life; aluminium cylinder heads for superior heat dissipation; 7075-T6 aluminium connecting rods for high strength; and aluminium crankcase for elimination unnecessary weight.
Quality Assurance: All compressor pumps are individually tested and certified for performance to required operating conditions.
High Quality Components: anti-friction bearings for smooth operation with lower horsepower; front and rear bearings for precise crankshaft alignment and long shaft life; fully enclosed, all metal fan-blade guard; fly wheel precision-balanced and fan-bladed for excellent cooling capacity; heavy duty, shaft-driven, gear-type oil pump for generous lubrication to critical wear areas for longer pump life; stainless steel, disc-in-plate valves for long wear and excellent heat resistance and dissipation; valve housings nickel-plated for corrosion resistance.

Easy to Operate and Maintain: quick change air-intake filters for easy maintenance; two crankcase covers for quick and easy main bearing replacement and access to crankshaft and connecting rods.
All NA Series blocks are built to the highest quality standards. In each one
