Item Number: 1566
Certified according to ATEX directive 94-9 EC
Integral thermistors (PTC *)
Maintenance-free and reliable
KTEX fans can be installed in any position and are easy to connect using the DS flexible connections. These fans have impellers with forward-curved blades and external rotor motors. The casing is manufactured from galvanised sheet steel, with a copper inlet cone. To protect the motor from overheating, PTC protective circuits in the motors must be connected to a monitoring apparatus certified according to Directive 94/9/EC that isolates the motor from voltage supply immediately when activated. We recommend to use UEK230E
for motor protection.
Explosion proof versions comply with EN 60079-0:2009, EN 14986:2007, EN 60079-7:2007. Improved safety in accordance with
