AIRVAK MECHANICAL VACUUM BOOSTERS

AIRVAK Mechanical Vacuum Booster Pumps, import substitutes, are used in growing number of applications where fast pump down times are required, and environment or energy usage concerns, rule out any alternative pump selection. AIRVAK  Booster Pumps enhance the performance, ultimate vacuum and pumping speed of oil-sealed/water-ring/dry vacuum type of mechanical pumps, which are widely used in the industry.

OPERATING PRINCIPLE

AIRVAK Vacuum Boosters are positive displacement pumps with two figure eight shaped impellers rotating in opposite directions inside the casing. As each lobe of an impeller passes the blower inlet, it traps a quantity of air equal to exactly one fourth the displacement of the blower.

This entrapment occurs four times per revolution. The entrained air is forced around the case to the blower outlet. Timing gears accurately position the impellers in relation to each other to maintain the minute clearances so vital to the high volumetric efficiency of the pump.

KEY FEATURES

• Boosts vacuum levels of backing pumps, thereby reducing process temperature
• Boosts volumetric displacement, Thereby reducing Process time.

Application:

•  Evaporative Concentration, Vacuum Distillation,
• Polymerization, Crystallization, Vacuum Impregnation,
• Vacuum Drying, Sterlization, Vacuum Cooling, Object
• Metallising, Roll Metallisation, Semi-conductor Processing,
• Manufacture of Vacuum & Microwave Tubes,
• Manufacture of GLS Automotive & Miniature Lamps, Tube Light
• Production, Sintering, Brazing, Electron Beam Welding,
• Heat Treatment, Ionic Nitriding, Tool Coating, Vacuum
• Casting, Degassing & Refining, Plasma Welding,
• Evaporation, Sputtering, Space Research and Development

AIRVAK Boosters Advantages

• High vacuum of the order of 0.001 Torr or better
• High pumping speeds at low pressures, capacity is boosted by 8 to 10 times or more
• Relatively low power consumption for such performance boosting
• Considerable reduction in pump down time of vacuum machine
• Prevents Oil back streaming from Rotary pumps
• Dry Pumping suitable for Gas/Vapour Loads

AIRVAK Boosters Features

• Entirely mechanical, light weight and compact design
• High operating speeds because of dynamically balanced rotors and helical ground gears for long life and quiet operation
• Can be mounted separately from the backing pump or directly on the inlet of the backing pump
• ISO Flanges
• Unique impeller design for high volumetric efficiency
• Compatible with all vacuum systems
• Efficient air-cooled design
