Kaeser BBC and FBC rotary blowers

The BBC and FBC series of rotary blowers from Kaeser are compact, quiet and energy efficient.

Suitable for the supply of low pressure compressed air in applications such as conveying and water treatment, the units are supplied complete with all sensors, controls and a choice of star-delta starter or variable speed drive.

The systems are CE and EMC certified. Their quiet operation is thanks to effective broadband sound and pulsation damping, which applies to both the machine and the pipework.

Operational reliability and uptime is enhanced due to the inclusion of a blower block with Omega profile rotors, while adaptive compression reduces energy consumption and long bearing life minimises maintenance costs.

Components such as control valves and exhaust silencers, which would normally be installed external, are integrated. In addition, the design allows all service work to be carried out from the front of the unit. With the star-delta equipped models, this makes it possible to install several blowers side by side.

All blowers come with an internal Sigma Control 2 controller to enable quick and easy blower mode selection, such as remote speed control or pressure control.

Performance parameters are monitored by sensors, automatically generating warning or fault signals. Optional communication via databus (multiple databus systems can be connected) allows operational status readout and enables the machine to be remotely controlled.

Efficient and energy saving, the rotary blower range covers air deliveries from 2 to 72 m³/min at up to 1000 mbar gauge pressure and 500 mbar vacuum.
