Vacuum and Pressure Handbook: Basic Concepts
|
From Gast Group
This handbook examines two interrelated segments of pneumatic power: pressure and vacuum. That is, the development and utilization of air pressure and vacuum to meet specific work needs. In terms of system equipment, this translates largely (but not exclusively) into the proper selection and sizing of commercial air compressors and vacuum pumps. The focus here is on smaller units-those appropriate to powering an individual machine or, at most, a small shop. Products & Services
Rotary vane vacuum pumps and systems move media through the pump using a rotating assembly in the pumping chamber. Typically, there are two or more rotating vanes that move the media from inlet to outlet. Rotary vane vacuum pumps are positive displacement pumps.
