KFK mixing chamber

KFK – removable metal mixing chamber with incorporated heat control damper and G3 filter for transported purification. The mixing chamber is fixed to the fan casing by means of lock-latches to ensure easy removal for cleaning. The fan configuration with KFK mixing chamber provides cold air supply to the mixing chamber as the operating temperature exceeds 90 °С and hot air removal as the motor is off.

Operating logic of KAM fan with KFK filter box

When air temperature in the fireplace hood reaches the set point, the fan turns automatically on (fig. 3b) and distributes purified hot air from the fireplace to other premises. It turns off, when air temperature falls down below the set point (fig. 3a). The fan equipped with a mixing chamber provides cold air supply to the mixing chamber (fig. 3c) if the transported air temperature exceeds +90 °C and hot air removal when the fan is off (fig. 3d).

Operating logic of KAM filter with KFK mixing chamber and GFK gravity damper

When air temperature in the fireplace hood reaches the set point, the fan turns automatically on (fig. 4b) and distributes purified hot air from the fireplace to other premises. It turns off, when the temperature falls down below the set point (fig. 4a). The BYPASS system is designed to protect the fan from overheating, for example, during power failure. In this case, the GFK damper is closed and hot air is moved through the bypass air duct past the fan. If the air supplied to the fan is too hot, the mixing chamber damper is opened, and cold air is supplied to the fan (fig. 4c).
