Busch Tyr rotary lobe blowers

Tyr rotary lobe blowers are high-performance generators for vacuum and overpressure which can be used for wastewater treatment, specifically in aeration applications. The robust design ensures the product is reliable and operationally dependable.

The blower is available in six different sizes, which can be individually adjusted to suit any application by selecting the drive and variable speed. The product is suited for aeration with overpressure, eg, aeration of fish tanks and biofilters. It is energy efficient and service friendly due to the non-contact design, whereby no operating fluid is required in the compression chamber.

The three-blade rotary blowers operate with two mounted parallel rotary pistons, which rotate in opposite directions within housing. The pumped medium is sealed in the space between the rotors and housing, where it is compressed and pumped through the housing to the gas discharge by the rotary motion and discharged. Once the medium has been compressed during the blower stage, it flows through the downstream discharge silencer.

The operating pressure, filter and gear oil level can be monitored via displays on the housing/sound-absorbing cabinet. The maximum nominal pumping speed offered by the largest of the blowers is 15.4-73 m³/min and many accessories are available, including an acoustic enclosure for noise-level reduction, making the blower very quiet. A non-return valve and heat sensor are also available.
