VILPE’s exhaust ventilation pipes effectively remove dirty and humid air from the building. This product category includes sewer ventilation pipes, vents, cowls, and other ventilation pipes for optimal ventilation. VILPE FLOW exhaust ventilation pipes are suitable for buildings with passive ventilation systems or those with mechanical intake and exhaust ventilation systems. The exhaust air is directed straight towards the sky, so all dirt particles are pushed far away from air intakes. In addition, VILPE FLOW exhaust ventilation pipes effectively keep rain water out. Their low pressure loss also ensures that VILPE FLOW exhaust ventilation pipes are energy-efficient. This reduces the energy consumed by the ventilation system as a whole – which is important not only because it reduces electricity bills, but also because of the corresponding reduction in the system’s environmental impact. The S-series exhaust vents are designed to be installed in the ventilation shaft, onto a silencer or in or other horizontal surface. The S-series exhaust vents are used, for example, in blocks of flats and terraced houses, when flat-specific ventilation is required. 125S FLOW Exhaust Vent 250 X 250: Exhaust vent for a flat surface with FLOW cowl.
