Made to work hard in corrosive environments.
The PRF fans have been developed especially for the exhaust of aggressive media.
This aggressive media fan is a robust plastic centrifugal fan ideal for applications where the extraction of dirt, corrosive gases, or other aggressive media will harm a standard fan. 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 and 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 handing can be easily adjusted by turning it, but the standard position is LG270. Download the handing form for more information and to select your configuration.
Suitable for danger zone 2 category 3G with classes IIA and IIB and temperature classes T1 to T4. A hazardous motor selection form must accompany all PRF EX fan orders.
To protect the motor from overheating, these fans have integral thermistors (PTC) with external leads which must be connected to the U-EK230E motor protection relay.
