Operating Principle:
The compression chamber is a toroidal channel in which an impeller rotates. The gas
trapped between the vanes is centrifugally forced to the periphery of the chamber and
swirls around the core before it is caught again by the next vane on the wheel, repeating
the process all around the channel, and transforming the kinetic energy into pressure. A
stripper separates the inlet from the outlet ports and helps in guiding the gas flow from
suction to discharge. The clearance between the impeller and the stripper is very tight to
limit the gas slippage.
The location, orientation, area of inlet/outlet ports, the geometry of the vanes (bending
radius, height, penetration, angle), the shape and area of the chamber, and the shape of
the channel impart different compressor characteristics (flow rate, pressure, efficiency),
offering multiple solutions for dealing with varied process conditions.
