Tough and ready for anything
Our single-block blowers provide maximum flexibility. The OMEGA series blowers with their three-lobe rotors minimise pulsation and include a wide range of rotary lobe blowers for stationary and mobile applications. They are manufactured in state-of-the-art, climate-controlled CNC production facilities and are rigorously tested at full load.

Highly versatile rotary lobe blowers – in stationary and mobile versions, suitable for both vacuum and pressure operation – for air and nitrogen conveying applications (OMEGA P and PN)
Blower with primary components made from chromium-nickel alloy for vacuum distillation / process water recycling (OMEGA B)
Vacuum blowers with pre-inlet cooling – suitable for alternating vacuum and pressure operation in tanker trucks and suction vehicles (OMEGA PV)
Rotary lobe vacuum pumps for fine vacuum applications (OMEGA WVC) in combination with a booster pump
Your advantages

Long service life:
Heavy-duty cylinder roller bearings completely absorb the continuously changing radial gas-forces that are exerted on the rotors. Service life of up to 100,000 hours is possible with the included bearings.
High flow rate = High-efficiency
Thanks to precision manufacturing we achieve minimal flank clearance, which results in reduced capacity losses through gap losses.

Mô tả chi tiết & Ưu điểm

Rotary lobe blower packages with OMEGA profileField of application (Normal air version Omega P)

Whether stationary or mobile, and in both vacuum and pressure operation – our rotary blowers ensure excellent performance for a wide range of applications. For example:

  • In water management (e.g. for aeration of sedimentation tanks)
  • Forced air generation (drying, cooling, separation…)
  • Combustion air supply
  • For pneumatic conveying of powdered and granular bulk materials





OMEGA P rotary lobe blower Field of application (Nitrogen version Omega PN)
Some bulk materials have to be conveyed in a nitrogen atmosphere within a closed system.
Leakage from system components – including rotary blowers – must therefore be kept to an absolute minimum.
PN series blowers were specially developed for these applications. They are available with three different drive shaft rotary lead-through seals, including a wear-free sliding ring seal.






OMEGA P rotary lobe blower – How it works

  1. Intake
  2. Conveying to discharge side
  3. Pressure equalisation
  4. Discharge

As the rotors turn, air in the inlet is trapped between the rotor lobes and the casing.
When the advancing lobe reaches the lip of an eccentric bore hole in the casing,
this “pre-inlet channel” allows gradual equalisation of pressure between the trapped inlet air and the air drawn in from the discharge side.
Pressure equalisation in two-lobe blocks occurs abruptly as the advancing lobe crosses the lip of the discharge port.
This is the main reason why three-lobe blocks generate significantly less pulsation than two-lobe blocks.
The air is then finally pushed out against the pressure in the pipe work.
