The level of vacuum required varies between applications, from low vacuum for central vacuum cleaning or clean rooms to high vacuum applications such as silicon wafer coating in semiconductor production.
A huge variety of applications involve the evacuation of containers, and the range of vacuum pumps available for these applications is equally diverse. Key factors to consider when selecting a vacuum generator include the volume to be evacuated and the required ultimate pressure in the container. Nearly all of the vacuum pumps in our product range can be used to meet requirements of this kind.
RH series rotary vane vacuum pumps are used in many different evacuation processes, where they excel due to their operational reliability and robustness.
