Roof ventilators for every purpose.

S-Vent roof ventilators for intake and extraction are designed for flat roofs and for air volumes of 500 to 5000 m3/hr.The roof ventilator cap and uprights are polyester fibre reinforced by glass wool, with a coating of grey polyester paint. This corrosion-free structure guarantees excellent weather-resistance.

Depending on whether intake or extraction is involved, roof ventilators are fitted with an overpressure-relief valve, rainfall protection caps, or a sound-absorber. There is an operating switch mounted on all roof ventilators. Thanks to the wood bolts supplied, the ventilator cap is easily mounted on the uprights.

Constant volume, numerous accessories.
Roof ventilators can be fitted with either a 230V 50Hz alternating current S-Vent ventilator or an EMC winding class B ventilator with integrated frequency control. Controlled by a 0-10 Volt signal. This produces a constant volume, irrespective of the pressure. As accessories in total projects we supply: ventilators, regulators of various types, grates/grate ventilators, tubes and fittings, flexible hoses.
