ROTARY LOBE BLOWERS

Efficient and Long-Lasting SDB Rotary Lobe Blowers

Rotary lobe blowers are used to provide air flow under pressure or vacuum conditions for industrial and commercial processes. Air Power Products Ltd. offers Greatech G-series and SdB Series rotary lobe blowers for this purpose. These blowers are designed to provide the most economical operation in applications requiring higher levels of pressure or vacuum (pressures above 4 PSIG and vacuums above 10” Hg.).

The SdB Series are tri-lobe blowers, which are known for their ease of installation and quiet operation. The noise levels are extremely low compared to other rotary lobe blowers, ranging on average from 58dBA to 84 dBA. These blowers offer minimal vibration during operation. The dry compression chamber provides an oil-free source of compressed air for pressure applications.  

The blower construction consists of a direct coupled, flange-mounted motor operating at 1750 RPM. This eliminates the use of vee belts and associated vee belt maintenance. Pressures up to and exceeding 8.5 PSIG can be achieved.
