PRAWIN CONSTRUCTION FEATURES

Casing & Side Plate : Made of C.I . Grade 20/25 with sturdy construction and its ribbed design for faster dissipation of heat generated by compression of air inside the casing.

Gears : Spur/helical are made up of alloy steel duly hardened to ensure perfect timing of rotars.

Rotars & Shafts : dynamically and balanced , carefully calculated involute profile of rotars with alloy steel shafts to ensure maximum volumetric efficiency with minimum absorbed power.

Bearings : Both rotar assemblies are supported by high load carrying capacity ball/ roller bearing to ensure longer operating life.

Lubrications : By splash at gear end, embodied by the compressor casing to ensure positive supply of oil gears&bearing.

Sealing : By high quality oil seal to restrict leakage of oil thus ensuring oil free air.

Installation : In horizontal / vertical direction depending up on the requirement of the usage .

PRAWIN COMPRESSOR ARE ALSO IDEALLY SUITED FOR VACCUME SERVICES

WORKING PRINCIPALS

Prawin compression : Consist of two involute profile rotars , mounted on parallel shafts, which rotate in opposite direction with an enlongated cylindrical housing closed at end by side plates. As the lobe passes the inlet, it traps a finite volume of air and carries it around the case to the outlet where the air is discharged. The cycle repeat four times with every one complete revolution of the driving shaft. The lobe run with a finite clearance and require no lubrication.

Pressure is not developed inside the blower but by the demand of the system . discharge pressure , therefore, varies to meet the load condition and the system resistance. Volume displaced is almost constant with pressure except for slight increase in slip at the pressure rises. Horse power required is proportional to the differential pressure across the suction and the discharged of the blower.

Prawin : Twin lobe rotary blower is a positive displacement machine which discharges a constant volume of air. The machine is used to transfer air and other gases from a low pressure to a high pressure. In pressure application the blower usually takes air from the atmosphere and transfer it to the system at a high pressure. In vacuum application the blower pumps air from the system and discharges to the atmosphere.
