For generating over-pressure in pneumatic pressure conveying systems used for conveying bulk materials. The flexible modular design permits installation of any blower unit and motor size for belt drive within the range of a nominal width. Consequently the system can be optimally adapted to the specific demands on the output as well as to any modifications which may become necessary later.
Due to the 3-blade rotors in connection with the pre-intake, a reduction of pulsation could be achieved thus taking completely new ways in the design of the device. All components of the unit have been installed on the basic construction. The basic construction incorporates purely metallic and completely wear-free installations which ensure a uniform reduction of noise over the whole speed range. Additional silencers on pressure end are normally not necessary. The very good long-term experience with V-belt drives has given grounds for developing this kind of drive further. The motor installed on a rocker drives the blower device with its 3-blade rotors via narrow V-belts thus generating the required pressure. This principle ensures that the belts have optimum tension at all times. Even after longer operation the tension need not be re-adjusted. The units come completely with all necessary accessories. Elastic support is a standard feature, special base plates are not required. After connecting the conveying line, filling the lubricating oil and establishing the electrical connection the blower is ready for operation. Thus the installation costs are reduced to a minimum.
