GNR Series Booster Fans

Description

GNR Series

Power Range Type: GRN

GRN types are characterized by their high flexibility.  The housing position and direction of rotation can be adapted to your system.

Flange sizes from DN80 to DN200 upon customer request.

For moist and corrosive gases and/or environments, the fan housing is also available in stainless steel. In this case, the type designation changes to SRN.

GRN Direct Drive (GRN/1G)

Direct drive fans are characterized by their compact design. In order to achieve a wide range of operating points even at fixed speeds, there are various models with different impeller diameters available.

Example Fan Type: EX-S-GRN48/120/500/1G

• Impeller direct mounted on motor shaft
• Standard flange size DN125 PN10 (others on request)
• Flow rate up to 500 m3/h
• Pressure up to 40 mbar
• Motor size 1.1 kW (400V/50Hz)
• Housing material GGG40 / Impeller from aluminum
• ATEX II2G or II3G (for zone 1 and 2)
