Fans - rectangular duct

Fans - rectangular duct

In the category of fans for four-sided ducts, there are mainly fans with the radial impeller construction. These rectangular fans are intended for more complex ventilation applications where higher pressure losses are expected to be overcome. Usually these are not silent fans, but our offer also includes fans with a sound-insulated housing that achieves acceptable noise parameters.

The KT fans are designed for a direct connection to rectangular ducting. The KT fans are radial single inlet fans with forward curved blades and with an external rotor motor. For easier service and maintenance, the fans are equipped with a tilting impeller. The fan casing is made of galvanized steel sheet. The air to be conveyed must be free of particles which could cause corrosion, engine fouling or impeller imbalance. They can be installed in any position and are adapted for speed control by changing the voltage. The fan speed can be controlled by a 5-stage transformer or by a frequency converter with a sine filter. The motors are equipped with built-in thermal contacts running to the motor screw terminal, which must be connected to the corresponding thermal overload relay. The KE fans can be installed in any position.
