Compressor design features and benefits
1. Horizontal configuration – low vibration requiring no special foundations
2. Castings in SG Iron meet stringent European environmental regulations
3. Pressurized crankcase eliminates gas venting to atmosphere during normal operation & stand by modes. Zero gas loss from compressor.
4. Crankcase pressure fed oil to all bearings & crossheads.
5. Exclusive low friction cylinder treatment in certain cases – longer ring life at high pressure.
6. Cylinders lubricated by metered upper cylinder lubricator pump extends cylinder bore and Piston ring life.
7. Uses SAE 40 lubricating oil - readily available
8. Fully lubricated design significantly reduces wear on valves & rings
9. Cylinders lubricated by metered upper cylinder lubricator pump extends cylinder bore and Piston ring life
10. Specifically designed for low inlet pressure operation 5-15 psig 4 valve 1st stage
11. Direct Drive of compressor eliminates power loss from drive belt slippage
