How a KAESER rotary blower works OMEGA P As the rotors turn, air in the inlet is trapped between the rotor lobes and the casing and is carried round to the outlet without being compressed. The casing bore toward the discharge port is slightly eccentric so that as the lobe approaches the port the gap between it and the casing begins to widen. This allows gradual equalisation of pressure between the air in the discharge port and that in the chamber behind the advancing lobe. Pressure equalisation in two-lobe blocks occurs abruptly as the advancing lobe crosses the lip of the discharge port....

COMPRESSORS Vacuum blowers with pre-inlet cooling Model: Omega PV Field of application For use in low vacuum ranges up to 100 mbar (a) or 900 mbar vacuum. Function If vacuum (yellow) occurs between the rotor and the casing ambient air (blue) enters the blower block via so-called pre-inlet channels as the rotors continue to turn. The two volume flows subsequently combine and the arising compression heat is dissipated throughout a much larger volume of trapped air. This approach therefore achieves the same discharge temperatures that are produced by normal blower blocks. Application examples...

COMPRESSORS Rotary vacuum pump WVC When producing fine vacuum in combination with a corresponding backing pump, the WVC significanltly increases pump suction capacity and vacuum performance. The use of a frequency converter is particularly beneficial, as the converter enables simultaneous activation of rotary vacuum and backing pumps at atmospheric pressure, thereby significantly reducing pumping time.
