Our positive displacement blowers can move any type of gas in a high vacuum. Our vacuum blowers are fitted with fluor rubber (FKM) O-ring seals at the casing flanges to provide unmatched vacuum tightness that prevents leakage.
They also come with a special oil slinger-piston ring-labyrinth seal between the bearing and conveying chambers and an adequately proportioned neutral chamber with condensate channels that you can purge with seal gas to achieve increased sealing.
Double radial seal rings with an oil chamber guarantee the drive shaft’s sealing; splash lubrication supplies the lubrication oil (PTFE or mineral oil) and is used to convey oxygen.
Direct coupling with a motor drives the blower. The unit consists of a cast connecting piece with perforated plate cover, flanged B5-motor, and flexible coupling in adherence with IEC standards. In addition, it has three PTC resistors.
With our vacuum systems, you can expect to enjoy:

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.
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.
AERZEN HV-type blowers are designed for moving almost any gas and are especially used in industrial high-vacuum technology. With a total of 19 sizes, the blowers cover nominal displacement intake volume flows from 180 m3/h to 97,000 m3/h and pressure ranges from 10^-3 mbar abs. up to approx. 200 mbar abs.
