PROPERTIES
ENERGY EFFICIENCY IS STANDARD AT AERZEN
AERZEN standards for blowers and compressors have always been high. And now, they are being applied to drive units, too. IE 3 motors ensure maximum energy efficiency.
And AERZEN standard motors are already certified for use in several markets, including the US, Canada and Russia, and are suitable for frequency converters.
DESIGN AND CONSTRUCTION
AERZEN vacuum blowers are provided with fluoro rubber (FKM) O-ring seals at the casing flanges. Further important advantages of the blower stage are vacuum tightness and air cooling. Lubrication oil is supplied by splash lubrication. The lubricant can be mineral oil, as well as PFPE oil, which is mostly used for conveying oxygen.
The HV series is equipped with a special oil slinger-piston ring-labyrinth seal between the conveying chamber and the bearing chambers. Additionally, an amply dimensioned neutral chamber with condensate channels is installed. In addition, the neutral chamber can be purged with seal gas, in order to achieve an increased sealing effect. The sealing of the drive shaft is guaranteed by double radial seal rings (FKM) with an oil chamber.
The blower is driven by direct coupling with motor. The driving unit consists of a cast connecting piece with perforated plate cover, flexible coupling and flanged B5-motor, equipped as per IEC standard and additionally with 3 PTC resistors. As standard, IE 3 motors are used for maximum energy efficiency.
AERZEN standard motors are already certified for use in several markets, including the US, Canada and Russia, and are suitable for frequency converters.
