ELMO-G Blower - Vacuum pump 1000 m3/h The blowers are made by German ELMO Vacuum Technology GmbH, a Siemens company in year 2002 and they are single stage, gas ring type. The vacuum pumps are in good operational condition. We have three identical pump units and originally the pumps were in dust suction operation and therefore the delivery includes 3 pcs high efficiency cyclone type dust filter with electric discharge vibrators. Motor speed is controlled with individual inverters. Units can be sold separately. ELMO-G vacuum pumps can be used for suction operation or as compressors in pneumatic transportation system. They have side-channel principle using gas ring as a sealing and the gas flows through the compressor along a helical trajectory and is repeatedly accelerated and thereby repeatedly compressed according to the required operating point. The blowers are oil-free and thus suitable for various applications. The blowersÆ have both suction and discharge noise silencer. For pump curves, both in suction and compression, as well as additional information please contact us.

The fan is made by German Pollrich Ventilatoren GmbH in year 2004 and it has been as a back-up emergency fan which has practically newer used and therefore the unit is new like condition. This fan was designed to blow explosive air/gas mixture (VOC) and therefore it fulfills category II 2G, temperature class 1 ATEX 95 norm of explosive proof design. The motor and fan are built on a common heavy duty frame and they are connected with a flexible coupling.
