The energy saving fan, types LEF and MEF with backward curving and self-cleaning impellers and air flows up to 24000 m³/h. Its high efficiency makes it very energy efficient and very suitable for speed control (e.g. by using a frequency inverter).
The fully galvanized fans come with galvanized grill and inlet, vibration pads, and bracket for outlet flange as standard. The fans can be used with or without our unique soundbox system and are available as spark-proof (EEXe T3).
Stainless steel
The LEF-MEF fan is also available in stainless (acid-proof AISI316) steel with epoxy painted impeller and inlet. Suitable for extraction of corrosive fumes from e.g. cabinets for recharging batteries and other aggressive environments.
The efficiency of the fan is in many situations optimized by the of Geovent Automatics such as PowerSmart and MulitiBox IV.
