Tyr rotary lobe blowers are available as vacuum generators and overpressure generators. The six different sizes can be individually adapted to suit any application perfectly by selecting the drive and varying the speed. Depending on the version, the innovative noise insulation reduces noise emissions by 4 to 5 dB(A) compared to similar blowers. The acoustic cabinet (accessory) enables the noise level to be reduced by a further 15 to 20 dB(A).

Easy to service
Thanks to the non-contact operating principle, no operating fluid is required in the compression chamber. The operating pressure, filter and gear oil level can be monitored easily via displays on the housing/acoustic cabinet. Belt tensioning between the drive and the blower stage is performed automatically, eliminating the need for inconvenient checks and adjustment of v-belts.


Oil-Lubricated Rotary Vane Vacuum Pumps

Principle of operation

The rotary vane technology enables a technically simple structure of the vacuum pumps. The consistently high vacuum level in continuous operation is guaranteed through circulating oil lubrication, perfectly coordinated materials and state-of-the-art and precise manufacturing. The standard oil separator ensures clean and oil-free exhaust thanks to its sophisticated extractor system with integrated oil return. When fitted with an optional gas ballast valve, even large amounts of vapour can be processed. A non-return valve in the inlet flange prevents air from flowing back into the vacuum chamber when the vacuum pump is switched off.

Dry Claw Vacuum Pumps and Compressors

Principle of operation

With claw vacuum pumps, two claw-shaped rotors turn in opposite direction inside the housing. Due to the shape of these claw rotors, the air or gas is sucked in, compressed and discharged. The claw rotors do not come into contact either with each other nor with the cylinder in which they are rotating. Tight clearances between the claw rotors and the housing optimize the internal seal and guarantee a consistently high pumping speed. A synchronization gearbox ensures exact synchronization of the claw rotors.

Vacuum Boosters

Principle of operation

Within the housing of rotary lobe vacuum boosters, two lobes rotate synchronously. Due to the special profile of the rotating lobes and their precise manufacturing, they do not come into contact with each other or the housing. This makes it possible to pump a medium without the need of any operating fluids. The synchronous rotation of the lobes is driven by a pair of gear wheels located on the shaft ends in the gearbox and separated from the compression chamber.

Positive displacement pumps are efficient in situations requiring low vacuums. There are many common positive displacement pumps, but there are two that are used for most industrial applications: the diaphragm pump and the rotary vane pump.

Rotary Vane Pump – The rotary vane pump is the most common vacuum pump. It consists of a cavity with a rotor that has vanes attached to it. They can often be a circular rotor that is offset inside of a circular cavity. The vanes seal the edges of the cavity by sliding in and out of the rotor. This design is simple and doesn’t require a lot of power. It is reliable and economical.
