Description
- Swing-out
- Speed-controllable
- Integral thermal contacts
- Can be installed in any position
- Maintenance-free and reliable
The KT models have impellers with forward-curved blades and external rotor motors. The motor and impeller are mounted on the access cover to facilitate easy maintenance. The casing is manufactured from galvanised sheet steel. To protect the motor from overheating the fans have integral thermal contacts with external leads for connection to a motor protection device. The fans can be installed in any position and are easy to connect using the DS flexible connections. The KT fans have a prewired, integral terminal box.
