VILPE’s exhaust ventilation pipes effectively remove dirty and humid air from the building. This product category includes sewer ventilation pipes, 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 P-series exhaust ventilation pipes can be led watertight with a pass-through set through a roof. VILPE pass-through sets can be installed on any roofs with the most common pitches. The pass-through set is always selected according to the roofing material of the roof. All the exhaust ventilation pipes in the P-series are compatible with all pass-through set types. Using P-series XL exhaust ventilation pipes requires an XL pass-through. 125C/IS/400: Insulated exhaust ventilation pipe with FLOW cowl. Includes a galvanized steel inner pipe with a lip seal.
