Classic static chimney cowl for ventilation or gas flues.
Static chimney cowl CAGI is a device, which uses the dynamic force of the wind to increase the chimney draught. The head creates a pressure difference forcing the air in the duct to move up. It is to be mounted on gravitation based chimney ducts endings: ventilation or flue-gas heating (dry fumes).

Cap protects chimney ducts from rain and snow. Aesthetical covering of ducts.
Caps are devices which protects the chimney duct from rain or snow. It is to be mounted on gravitation based (natural) ventilation or flue (gas, oil) ducts. DARCO offers:
– Cap with base (WDA) Ø100÷Ø250 Cap with base is a device that protects the chimney duct (ventilation, flue) from rain or snow.
– Cap (DA) Ø100÷Ø250 Cap is a device that protects ventilation and flue chimney ducts from rain or snow.
– Cap with force-in mounting base (DA-PT) Ø100÷Ø250 Cap is a device that protects ventilation and flue ducts from rain or snow.
– Cap in a box DAP Ø60÷Ø80, Ø100÷Ø130, Ø140÷Ø180, Ø200÷Ø250 Cap in a box is a chimney cap of full value that fits in … a pizza box. Unique mounting method, with no usage of tools needed, universal sizes and simple installation, makes it a good solution for all chimney pipe endings. Rigid design and reliable mounting method ensures that the cap is as durable and aesthetic as a traditional chimney cap. Packing in small box is a great advantage of this solution, allowing easy storage and cheap logistic.
– Envelope-type cap, Sombrero-type cap They are an aesthetical ending of chimney duct. These products are produced upon individual order.

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.

Cowl designed esspecialy for smoke ducts.. It uses wind to increase chimney draught in most efficient way.
Self-adjusting chimney cowl Rotowent DRAGON is a device, which, in a dynamic way, uses force of the wind to increase chimney draught. The cap always places itself in the opposite direction to the wind no matter of its strength or direction. It is to be mounted on gravitation based chimney ducts endings: flue (gas, oil) and smoke. Thanks to the special, patneted, rotating system with ball bearings placed outside the cap, it can withstand very high temperatures, which can be achieved in wood or coal burning stoves.
