EX Centrifugal Fans

Compact, explosion-proof solution for ventilation of battery charging and industrial facilities

  • Explosion proof fan certified according to ATEX 2014/34/EU

  • Compact and robust design

  • Easy to install in any position (mounting brackets included)

Safety first

EX fan designed for use in battery-charging rooms, fume cupboards and other demanding environments where explosive atmospheres can occur.

Compact and Durable

The fan combines a compact design highly resistant to environmental stressors with a reliable ATEX rated AC motor.

Easy to install

EX fan supplied with preinstalled mounting brackets and premounted terminal box which simplifies installation process on site. Connection kit (accessory) allows to simplify connection to the standard circular ducts.

Explosion-Proof

The EX series is classified as II 2 G Ex db eb h IIB+H₂ T4 Gb.

That means it could be used for hazardous areas within zone 1 and 2 extracting gases and mixes of groups IIA, IIB and also hydrogen (H₂), temperature class T1, T2, T3 and T4.

Construction

The casing of EX fans is made from casted silumin alloy. Terminal box integrated to the motor enclosure. Mounting brackets made of galvanized sheet still connected to the motor. Single phase version of the fan is also completed with capacitor.

Impeller

EX fan uses lightweight single inlet radial impeller with forward curved blades made from aluminium.

Motor

EX 3-phase fans are equipped with voltage controllable, explosion proof AC motors, approved by ATEX. Motor has an integrated cooling impeller.

Motor protection

EX fans have integrated PTC (Positive Temperature Coefficient) protective circuits with external leads for connection to a motor protection device (separate accessory). We recommend to use UEK230E motor protection, certified according to ATEX directive 2014/34/EU.

Control

The EX 3-phase fans can be controlled by reducing voltage via 5-step speed regulator. The EX 1-phase fans are not voltage controllable. If a controllable EX 1-phase fan is needed, the corresponding EX 3-phase fan must be used in combination with a pre-programmed frequency converter (#474200).

Installation

Fan can be installed in any position by using preinstalled mounting brackets. In case of installation to the circular duct system we recommend to use dedicated connection kit (additional accessory).
