Application

Roof fans ERF are manufactured in accordance with both international standard ISO9001 and standard of the quality assurance system in the case of products intended for use in areas with explosion hazard – EN ISO/IEC 80079-34. They meet requirements provided in Directive ATEX 2014/34/UE, they are designed for use in areas with explosion hazard excluding mines and mine excavations.

They meet requirements for group II category 2G/3G zone 1 and/or 2. They are designed for outdoor installation in connection with supply system. The transported medium temperature can not exceed -20°C to 40°C.

Construction

Fan enclosures made of galvanized steel sheet, powder painted.

The elements which minimize sparking risks are used in structure, including sheet brass inlet.

Electric motor

Three-phase (400V, 50Hz) motors with external impeller, suitable for use in areas with explosion hazard, equipped with posistor sensors - PTC. The motors must be protected by using a dedicated (no. Art. 91040858) protective relay (certified II (2) G - in accordance with Directive 2014/34/UE) and an external contactor.

The motors are suitable for speed control by means of transformer voltage regulator (minimum voltage - 115V) - contact the manufacturer is required.
