GCK DRAUGHT GENERATOR

Its principle is to increase chimney draught no matter of what the chimney height, wind speed or other natural conditions are.

GCK DRAUGHT GENERATOR is a chimney fan that is is to be mounted on the top of a chimney (flue or smoke). Its principle is to increase and stabilize chimney draught no matter of what the chimney height, wind speed or other natural conditions are. Draught generator creates underpressure in the chimney duct using a special physical effect – called injection. It is based on creating the stream of airflow in the secondary duct, which creates underpressure in the main chimney duct. Air movement is caused by ventilator which is placed outside the duct. This working mode does not block the chimney duct and does not obstruct the fume extraction as well as allows the device to withstand high temperatures.

It is to be mounted on smoke chimney endings mostly in individual housing.

Usage:

  • when there are wind fluctuations on the chimney duct ending, caused by its bad location
  • when there is an unfavorable terrain configuration, with strong and frequent winds
  • when there is a lack of chimney draught or it is too weak (f.e. when the chimney duct is too short)
  • in order to stabilize and improve the chimney draught in a fireplace or boiler

ADAPTORS

They allow draught generator chimney fans to be mounted on chimneys of different than their nominal diameters.

Adaptors allow draught generator chimney fans in -B-K mounting version to be mounted on single walled chimneys of different than their nominal diameters.

Example dimensions: Ø150/130 , Ø200/180 [mm]
Material versions: chrome-nickel steel sheet

Other adaptors and reducers made upon individual orders.

CHIMNEY COWLS BASES AND FITTINGS

Chimney covers with caps enables building up top of concrete chimneys with vertical ducts in an easy way.

Chimney bases allow to connect various types of chimney cowls to the chimney.

Chimney covers with caps enables building up top of concrete chimneys with vertical ducts in an easy way. This type of covering protects ducts from rain and snow as well as assures aesthetical chimney top finishing. The solution allows building up chimneys, which are made of prefabricated elements covered with a concrete cap. Elements of the set should be fixed to concrete cap with mounting elements like screws or silicone.

Chimney bases allow to connect various types of chimney cowls to the chimney. Different types of bases are designed in order to create the best possible solution for tight and secure connection to the roof or chimney.

USAGE:

  • ventilation
  • smoke extraction
