DV-EX Roof Fans

Explosion-proof centrifugal roof fan with vertical discharge

Certified according to ATEX 2014/34/EU
Sizes 315 up to 500 inclusive tilting device

Safety first

DV-EX roof fans are designed for challenging environments where explosive atmospheres can occur. They are tested according to ATEX directive 2014/34/EU to ensure they’ll perform as intended after installation.

Relability

The casing made out of seawater-resistant aluminium with an inside galvanised steel frame is hard-wearing. This makes the fan also suitable for coastal applications.

The combination of casing and motor construction ensures to minimise the need for maintenance of the fans and allows long continuous operation.

Performance

DV-EX could be used for zone 1 and zone 2; Field of application for gases of groups IIA, IIB and also hydrogen, temperature class T1, T2 and T3.

Construction

The casing casing is manufactured from sea water resistant aluminium. The base frame is manufactured from galvanised steel and the inlet cone from copper. A powder-coated bird guard manufactured from galvanised steel is integrated in the casing.

Impeller

The DV-EX fans use radial impeller with backward curved blades. These are made out of aluminium, dynamically balanced and paired with corresponding external rotor motors.

Motor

Voltage controllable, explosion-proof, 3-phase external rotor motor. Separate “Ex-e” connection box available as an accessory.

Motor protection

Integrated PTC thermistors, to be connected to a motor protection device.

Control

Speed controllable by a 5-step transformer.

Installation

The DVS-EX are for outside installation.
