WDBE 3G/3D

explosion-proof roof fan

Anyagok:

WDBE are explosion-proof roof fans with horizontal discharge. The fans of the WDBE series meet the requirements of the EU ATEX Directive 2014/34/EU on devices intended for use in potentially explosive atmospheres.

Fans adapted to work in explosion hazard zones 2 and 22.

Zone designation:
Z1 – zone in which a mixture of gases, vapors or mists may occur under normal operating conditions.
Z2 – zone where there is a low probability of an explosive mixture of gases, vapors or mists, where the explosive mixture may occur only for a short time.
Z22 – a zone where there is a low probability of an explosive dust mixture and there is a short time, e.g. during a breakdown.

FAN MARKING acc. to ATEX:


Temperature class for gases: from T1 to T3
Maximum surface temperature for dust up to 120°C
Ambient temperature: up to +40°C
Explosion group for gases: IIA and IIB
Explosion group for dusts: IIIB

The fans of the WDBE series.

The fans of the WDBE series are manufactured in an explosion-proof and chemical-resistant standard, thanks to which they are widely used in many branches of the chemical industry, e.g. refineries, sewage treatment plants, chemical plants, battery rooms, paint shops, etc.

The fans are intended for roof mounting on standardized round roof bases (bases B/I; B/II). A three-phase explosion-proof motor was used, adapted to speed regulation (required use of a dedicated inverter offered by TYWENT and an EX relay). The impeller and the fan housing are made of acid-proof sheet metal, additionally the housing is covered with a special anti-electrostatic coating.
