Complete chimney for corrugated appentice roof

Radial or centrifugal fans that propel air in a radial way. The air inlet forms a 90º angle with the outlet in such a way that the air enters axially and is expelled outside radially.

Pile up chimney for corrugated appentice roof

Pile up chimney for corrugated appentice roof

Exafan has created a new type of removable and stackable chimney designed to work in air extraction mode, to lead the air flow inside the farm towards the required areas thanks to its diffusor. 

The concepts of conic entrance with a conic exit are both linked, this way; we manage to link the notion of easy assembly and transportation optimization with that of efficiency and ventilation system performance in one single product.

Aerodynamics : The air guide or the air inlet cone of the ventilation chimney was designed to favor the air flow and improve the global aerodynamic performance of the ventilation chimney.

Air flow: The ventilation chimney was designed to provide with the maximum air flow by reducing the fan electric consumption due to the conic shape of the air outlet enlargement producing a Venturi effect. They offer the possibility of a more simple and reduced room, which makes them more practical and economic. 7 times greater transportation capacity than for conventional chimneys.

The new conic chimney model allows a more fluid and quicker air extraction due to the Venturi effect caused by the air inlet and outlet through the chimney. 

The conic inlet and outlet construction principle ensures an improvement of the fan performance.
