Mechanical blower technology has existed for over 150 years and has proven to be a cost-effective solution to dramatically increase vacuum pumping speed. The most common type employs the figure-eight shaped Roots lobe, which is used in Stokes, Leybold, Edwards and many other manufacturers blower offerings. Adding a blower (or booster as they are often referred to) to your vacuum pump is quite economical as you can typically increase pumping speed more than 10X for less than double the price of your primary pump. Whether dry, rotary vane, rotary piston or even liquid ring technology, the addition of a blower is feasible with adequate consideration.
Of primary concern is maintaining a safe pressure differential between the blower and the rough pump. Quite simply, controlling the timing and speed of the blower operation at high pressure is the key to a sound system. Each manufacturer will employ one or more of the following mechanisms to enable this:
- Fluid Clutch
- Bypass Valve
- Vacuum Switch
- Frequency Inverter
