Positive Displacement Blowers

The basic unit consists of two figure eight shaped impellers mounted on parallel shafts. The impellers rotate in opposite directions within a cylindrical casing. As each impeller passes the inlet, it traps a definite volume of air/gas and caries it around the casing to the discharge where the gas is expelled. The cycle repeats four times with every revolution.

All Roots rotary positive blowers have close tolerances between the impellers and casing to minimize back-slippage of gas and to improve efficiency.

Centrifugal Blowers

Gardner Denver multistage centrifugal's are the prove standard for water and wastewater treatment applications requiring continuous, low-noise operation with minimal maintenance requirements. Primarily used for aerobic digestion, multistage centrifugal's can be throttled via an inlet butterfly valve making them an excellent choice for controlling dissolved oxygen (DO) in the wastewater. Gardner Denver exhausters can also be used in sludge digestion to exhaust the digester gases from the gas holder in channel aeration and in filter backwash applications for water treatment. Gardner Denver offers a wide range of blowers/exhausters, each having its own unique performance characteristics and design features to match your application requirements. Gardner Denver blowers/exhausters are available in complete engineered solutions packages featuring electric, turbine or VFD drives.
