Centrifugal Blowers/Exhausters

Untitled Document

Cullum and Brown can offer multiple options for applications that require a single or multi-stage centrifugal blower/exhauster. Centrifugal units can provide more efficient airflows and longer life than alternative air movers. Pressure and vacuum ranges exceed those capable by positive displacement blowers.

Our first product offering is the Gardner Denver line of centrifugal blowers, which consists of Lamson and Hoffman. Gardner Denver purchased Lamson in 1996 and Hoffman in 2001. The primary goal with this acquisition was to keep the most durable and advanced designs of both manufacturers to give our customers the best solutions for their centrifugal applications. There are currently 22 models to choose from to assure the most appropriate blower will be recommended for the required air flow. These models include both a cast and a fabricated type unit. A variety of design options is available from the factory, including special coatings, materials of construction, seals and electrical controls.



Cast Series:
Airflow to 41,000 CFM
Pressure to 22 PSIG
