PFPK EX are explosion-proof side-chamber fans. The PFPK EX 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.
PFPK EX fans are used in many technological facilities of the chemical industry where there is a risk of gas explosion. PFPK EX fans are used e.g. in laboratories, paint shops, gas stations. The fan housing is made of acid-resistant steel, thanks to which it can also be used in facilities with increased chemical aggressiveness, e.g. sewage treatment plants.
