WBE are explosion-proof side-chamber fans. WBE series fans meet the requirements of the EU ATEX Directive 2014/34/EU on devices intended for use in potentially explosive atmospheres.
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.
WBE fans are used in many technological facilities of the chemical industry where there is a risk of gas explosion. WBE fans are used, among others, in laboratories, paint shops, petrol stations. The interior of the fan is made of acid-resistant steel, so it can also be used in facilities with increased chemical aggressiveness, e.g. sewage treatment plants.
Fans designed for duct mounting. The fan is equipped with a round inlet ended with a mounting flange and a rectangular outlet frame. At the customer’s special request, it is possible to make round reducers for SPR ducts. Impeller and fan spiral made of stainless steel. The fan impeller has blades bent forward, thanks to which it is characterized by a low noise level. The housing is additionally covered with a special anti-static coating. The fans are equipped with an explosion-proof motor with a three-phase power supply dedicated to zone 1 (2G). The fan is not suitable for speed regulation. The fan with the possibility of adjusting the speed with an inverter is available on special request. The fan motor is located outside the flow of the medium, the mounting base for the motor is made of powder-coated steel. If there is a need for additional protection of the fan from weather conditions (outside), it is possible to make a special version (special painting of the motor, acid-resistant base, rain cover).
