Combined supply and exhaust ventilation systems for various premises where high air capacity at relatively low system resistance is required. FKO fans can be used for direct air exhaust or pressurization in smoke ventilation systems. FKO fans are suitable for outdoor wall mounting.
The fan casing and the impeller are made of steel with a polymeric coating. FKO fan terminal boxes are equipped with a cord for remote connection. FKO fans are fitted with an external terminal box mounted on the fan casing.
The impellers are powered by two, four or six-pole, single or three phase asynchronous motors with an external rotor and built-in thermal overheating protection depending on the model. Ball bearings in the motor provide a long service life designed for at least 40 000 hours. Motor protection rating IP 44.
Both smooth or step speed control are performed by means of a thyristor or autotransformer controller. Several fans can be connected to one controller if the total power and operating current do not exceed the rated controller values.
FKO fans are installed into a duct by means of connecting flanges. The fan is powered through the external remote terminal box. Power supply and installation should be performed in compliance with the manual and wiring diagram on the terminal box.
