Rotary Vane Vacuum Pumps

Rotary Vane Vacuum Pumps are the most popular and the most widely used vacuum pump across the industry. There are several reasons for that: First reason is that Rotary Vane Vacuum Pumps provide a great vacuum performance heavy duty industrial vacuum pumps are capable of 1 millitorr of ultimate vacuum (standard duty vacuum pump will reach about 15 millitorr). Second reason is that Rotary vane vacuum pumps come at a great price. A heavy duty industrial vacuum pump costs a few thousand dollars; a standard duty rotary vane vacuum pump can be bought for a couple of hundred dollars. Rotary Vane Vacuum Pumps are readily available, easily serviceable, fairly easy to maintain, and long lasting. Disadvantages of Rotary Vane Vacuum Pumps is that these emit oil mist – an oil mist eliminator installed at the exhaust is recommended on every rotary vane vacuum pump.
