WOKE are explosion-proof duct fans. WOKE series fans meet the requirements of the EU ATEX Directive 2014/34/EU on devices intended for use in potentially explosive atmospheres
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.
The WOKE fan, thanks to its compact housing, is used in many technological installations of the chemical industry where there is a risk of gas or dust explosion. They are used, among others, in battery rooms, laboratories, paint shops, gas stations, refineries and sewage treatment plants.
The fans are intended for installation on round duct systems. The fan is mounted using mounting flanges for flange-connected ducts or for spiro ducts with nipple connections (additional counter-flanges must be used). Explosion-proof motors for zone 1 were used, not adapted to speed regulation (there is also a possibility of execution with a motor adapted to speed regulation at the customer’s special request). The fan casing is made of steel sheet covered with a special anti-electrostatic coating. At the customer’s special request, it is also possible to make it of acid-resistant steel.
