For generating over-pressure in pneumatic pressure conveying systems used for conveying of bulk materials in continuous operation. Another interesting application of the unit is its use as an aeration blower providing compressed air for aeration bottoms as used for discharging bulk materials from containers resp. silos.
Pressure blowers of the D50 series ... ring blowers operate according to the side-channel principle. The air flows through the compressor on a helical path and, depending on the required operating point, is accelerated and consequently compressed several times. Thus higher pressures are often reached than is possible when using radial blowers with the same blower wheel diameter and the same speed. The units of this series operate with low noise, maintenance-free and therefore most economic. The maximum temperature of the conveying medium and the ambient temperature is 40° C. 50 and 60 Hz versions are available depending on where the unit is used.
