- 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.

Our comprehensive approach to life cycle cost management: Superior efficiency, easy operation, service-friendliness, and the latest in technology to keep performance high well into the future.

Field of application
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
|
|
|
|
Field of application
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.

Vacuum Blower with Pre-inlet Cooling: Model OMEGA PV
|
|
Field of application- For use in low vacuum ranges up to 1.5 psi (a) or 13 psig pressure differential.
- Vacuum intake capacity: up to 4238 cfm
Application examples- Mobile use, e.g. in tanker trucks and suction vehicles.
How it works
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.

|
|
|
|
|
Field of application- Specially designed for steam compression in vacuum operations in combination with water injection cooling.
Options- Rotors and block casings: cast stainless steel or chromium-nickel cast iron.
- Several options for internal seals for rotary transmission lead-through (corrosion-resistant and wear-free).
- Various special seals for drive shaft rotary lead-through for different working environments.
- Conveying direction: Vertical, from top to bottom (adjustable for different set-ups).
|
|
|
|
Field of application- For fine-vacuum applications
- Nominal flow capacity up to 4002 cfm
- Dry compression
- For use in pumping units in conjunction with a booster pump for increased suction power and vacuum pressure.
Reduced pumping time through frequency converter.- The optional frequency converter allows simultaneous activation of a rotary lobe vacuum pump and booster pump at atmospheric pressure.

OMEGA P Rotary Lobe Blowers - How They Work
|
|
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 equalization of pressure between the trapped inlet air and the air drawn in from the discharge side. Pressure equalization 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.
