ATEX fan, impeller with backward curved blades

ATEX Explosion-proof products


The energy saving fan, types LEX and MEX with backward curving and self-cleaning impellers and air flows up to 24.000 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.

The LEX/MEX fans are manufactured according to the ATEX directive 2014/34/EU.

The fans are delivered for ATEX zones 1, 2 (Gas), and 22 (Dust). The motor of the fan may differ depending on the zone it will be used for.

If the fan is to be used in combination with a frequency inverter, the motor has to be suitable for this purpose.

The efficiency of the fan can often be optimized by the of Geovent Automatics such as PowerSmart and MulitiBox IV. Read more here.

Stainless steel
The LEX/MEX fan is also available in stainless and acid-proof steel with epoxy painted wheel and inlet. Suitable for extraction of corrosive fumes from e.g. cabinets for recharging batteries.
