SN

The stainless steel roof cowl is made of durable stainless steel SS304. It is made to increase the static pressure of the ventilation duct and to ventilate the interior spaces without the use of electricity.

It only needs natural air flus, this eliminating the need to install electrical wiring on the roof, where the fan is installed.

The used material guarantees long-term durability even in demanding outdoor conditions. SN saves you electrical energy and guarantees continuous ventilation of interiors and exhaust of warm air in the summer months. It prevents back draft and increase the static draft of the ventilation duct.
