Rotary piston blower unit
55 - 160 m³/min, max. 1 000 mbar | HB series
KAESER
Removable panels in the sound enclosure allow easy access for all servicing work e.g. oil and filter inspection / changes, V-belt tensioning.
High-efficiency motors
EFF1*** drive motors (IP 55 with insulation class F) ensure optimum blower efficiency and generate considerably less heat during operation than other motors.
Automatic belt tensioning
Irrespective of motor weight, the pivoting motor base with tensioning spring automatically ensures optimum belt tension and, as a result, transmission efficiency. This system consequently also reduces servicing and maintenance costs.
Simple oil change
An oil drain-line is installed next to the enclosure door to enable quick and easy oil changes without having to carry out complicated disassembly work.
Independent fan
The ventilation fan for the sound enclosure has its own separate motor to ensure optimum cooling performance, which is especially important for frequency controlled units.
High efficiency cooling air flow system
Outstanding cooling performance is assured, as the drive motor is equipped with its own cooling air intake and ambient air is used for the blowing-air. This results in maximum efficiency and high capacity.
Unloaded starting
The optional Unloaded-Start Valve (USV) is located under the sound enclosure.
