Description

APPLICATIONS
Chimney fans for hot air distribution allow creating fully-featured air heating system based on a fireplace. Used for air distribution with the air temperature range 0°С to +150°С.	Such system is the perfect solution for heating of seasonal houses that serve as a second residence during winter time and provides fast and efficient hot air distribution from chimney to other premises.
DESIGN
The fan casing is made of galvanized steel and equipped with heat- and sound insulation of fire-resistant mineral wool. The casing is perforated for the internal air circulation and motor cooling.	The temperature controller is used for setting the temperature level for the fan switching on and off. Fan startup is effected within the range of 0 °С to +90°С depending on the air temperature generated inside the fireplace heat exchanger.
MOTOR
The fans are supplied with single phase motors for operation in 230/50Hz power supply network. Insulation Class F. The motors have integrated overheating protection with automatic restart.	The motor is placed off-airflow and is equipped with forward curved impeller blades as well as ball bearings for long service life. The fan models marked KAM are equipped with asynchronous motors and extra impeller for air blowing-off and cooling.
SPEED CONTROL
Both smooth and step fan control is performed by means of the thyristor or autotransformer (Models KAM, KAM Eco).	The fan speed is controlled within the range of 0 to 100%.
MOUNTING
The fireplace fans are designed for connection with round air ducts. The fans can be mounted in any position with respect to the airflow direction indicated with a pointer on the casing. Access for the fan maintenance shall be reserved.	Air ducts for warm air supply should be mounted from the fan to each heated room. Concealed air duct system with forced warm air circulation allows saving space in the house and blends into house design.
ACCESSORIES
FFK – removable G3 metal filter for transported air purification. The filter is connected to the fan casing by lock-latches to provide easy removal of the filter for cleaning. 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. GFK - gravity backdraft damper to prevent air back draft in the system. Such fan configuration that includes KFK mixing chamber and GFK backdraft damper ensures fan motor overheating protection based on BY-PASS actuation, in particular when the motor is not running due to no power supply. This design enables backdraft damper shutting and hot air distribution to other premises through ventilation ducts when the motor is not running.

KAM fan operating logic
	When air temperature in the fireplace hood reaches the set point, the fan turns automatically on and distributes hot air from the fireplace to other premises. It turns off, when the temperature falls down below the set point.

Operating logic of KAM fan with FFK filter box

When air temperature in the fireplace hood reaches the set point, the fan turns automatically on and distributes hot air (purified by the FFK filter) from the fireplace to other premises. It turns off when the temperature falls down below the set point.
Operating logic of KAM filter with KFK mixing chamber and integrated heat control damper
	When air temperature in the fireplace hood reaches the set point, the fan turns automatically on and distributes purified hot air from the fireplace to other premises. It turns off, when air temperature falls down below the set point. The fan equipped with a mixing chamber provides cold air supply to the mixing chamber if the transported air temperature exceeds +90°С and hot air removal when the fan is off.

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 and distributes purified hot air from the fireplace to other premises. It turns off, when the temperature falls down below the set point. 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.
