Roots Blower Vacuum Pumps
Roots Blower Vacuum Pumps are used when a large amount of Volumetric Airflow is Required. Root Vacuum Pumps cannot operate independently and must be used in conjunction with another roughing pump such as Rotary Vane Pump or Piston Pump. The advantages of a Roots Vacuum Pump is that the Pumping Speed can be increased by a factor of 5 up to a factor of 10; meaning that a 20 CFM Rotary Vane Vacuum Pump can now be boosted to pump 120 CFM!
Our Work: Research, Development, and Testing of Weather Balloons inside a Clear Vacuum Chamber
A wonderful company (more like one of the best companies in the world) which is currently involved with the research, development, and testing of high-altitude weather balloons, had a need for a vacuum chamber capable of achieving about 100 micro Torr (Micron) of ultimate Pressure for their testing environment. Fortunately, acrylic vacuum chambers are the perfect choice when it comes to Low, Rough, and Medium Vacuum.
