GCKV Model

Principle work GCK Ventlab is to increase chimney draught no Principle work GCK Ventlab is to increase chimney draught no matter of what the chimney height, wind speed or other natural conditions are. GCK VENTLAB 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.

GCK CAP (DA-GCK) openable

Its main function is the protection against rain and snow. Thanks to its unique construction it does not block the exhaust outlet of the generator and, at the same time, substantially increases the draught while the wind is blowing. The cap is equipped with openable plug making it easy to access the chimney without the necessity to disassembly the cowl or to use any tools.
