In compressor diffuser vanes, the vanes are designed in such a way that their leading edges will be inline with the direction of the gas flow from the impeller. From this point, vane curvature will force the gas to flow and be slowed down in a way that favors a particular engine speed or torque requirement. Vanes are used to alter the pressure ratio and flow characteristics of the compressor. Compressors with vane type diffuser normally have high peak efficiency. They frequently have a narrower range than compressors with vane less diffuser.

Compressor Fluids are recommended for cooling and lubricating continuously operating rotary screw & vane compressors, which operate at high discharge temperatures. Compressor fluids are not used to compress wet or sour hydrocarbon gases. These compressor fluids are compatible with all compressor oils except polyclycols and all standard seal & hose materials.

Compressor Intake Valve features straight-through design for low pressure drop, TFE valve seat for tight seal, one piece housing, side ports for pressure taps, two 1/4 in. NPT auxilliary ports and operating pressure 175 PSI.

Compressor oils are used to lubricate both the working parts and the pressurized spaces in a compressor. The purpose of the lubricant in the pressurized section is not only to reduce friction and wear but also to improve sealing of the pressurized spaces and to provide cooling. The compression process generates a lot of heat and in general, the higher the final compression temperature of the air at the outlet from the compression space, the higher are the requirements placed on the oil with respect to its oxidation stability and resistance to deposit formation.
