Tornado II roof ventilators are intended for use in ventilating areas of large cubic capacity like warehouses, halls, etc. A large performance scope ranging from 1000 to 12 100 m3/h makes it easy to select a ventilator to suit any client.
The ventilator body is made of a polyester and glass composite. The body is coated with gel-coat layer, which increases its durability and make resistant to mechanical and chemical factors. It also protects the product from moisture and the negative effect of sunlight.
Owing to the high quality of materials used for manufacturing the body, the element in fact does not require painting, and the period of operation does not affect the intensity and durability of the pigment used.
The standard colour of the ventilator is navy blue (RAL 5011), however, it is possible to paint it according to the customer's requirements within the RAL palette.

WDD roof ventilators belong to the industrial ventilator group, and due to its specific construction, it is classified as centrifugal fans with vertical air exhaust.
WDD ventilators may be installed on roofs where because of space shortage the exhaust is near the fan. Vertical dumping of the air minimises the risk of intaking used air back into the rooms.
The construction of the ventilator is made of galvanized steel sheets, and the body and the element protecting the electric motor from rain and snow is made of aluminium sheets.
The flow capacity ranges from 1 700 to 16 000 m³/h.
