VACUUM BOOSTERS

U.S. Vacuum Aerzen See also: Used Equipment

Vacuum boosters are auxiliary pieces of equipment that are used in conjunction with vacuum pumps to increase the capacity and/or vacuum level of the pumping system. Vacuum Boosters must be used in series with vacuum pumps with the booster acting as the first stage discharging into the inlet of the vacuum pump.

Vacuum boosters are high speed (3600 rpm) non-lubricated gas "accelerators" that move a high volume of gas/vapor which is compressed in the interstage manifold between the booster and it's accompanying vacuum pump. The vacuum pump sees the same Volume of gas as it did before, but at a much higher operating pressure than before.

Vacuum boosters are the most COST EFFECTIVE choice for increasing the capacity of existing or planned vacuum systems.  Sized from 2:1 to 10:1 compressions ratios (depending on the operating pressure of the system) they are used as standard in many high volume pumping applications.

The following are the thermodynamic limits, used as a general rule of thumb, for selecting vacuum boosters.

*These values are a rough guide for selection, ALWAYS call for assistance before selecting a booster for your system.

Vacuum boosters provide high speed acceleration of gas removal by means of a non-lubricated, rotary lobed, positive displacement pump. A HIGH VOLUME of gas at relatively LOW PRESSURES are pumped via high speed (3600 rpm) lobes to the "backing" vacuum pump where the gases are then handled at a greatly REDUCED VOLUME and HIGHER PRESSURE.

This follows our Pressure-Volume relationship of gases where each one is inversely proportional to the other. High speed pumping is obtained with the least amount of capital expenditure.
