The PRF-EX Ex d fans have been developed especially for the exhaust of aggressive media. This is the right fan when corrosive gases, contaminated air or other aggressive components are part of the exhaust air. Typical applications are medical facilities, the food-, electrical-or chemical industry. The sintered casing from PP offers a variety of applications with its connectors from ø 125 - 250 mm. The casing can be easily adjusted through turning it (Standard position is LG270, see picture). Suitable for danger zone 1 and 2 category 2G and 3G, group IIA, IIB and hydrogen, and temperature classes T1 to T4. The IEC standard motors Ex d specification are speed controllable by frequency converter. Ex d motors with mounted terminal box in Ex e specification. To protect the motor from overheating these fans have integral thermistors (PTC) with external leads which must be connected to a motor protection relay.
