An aerator of the Alipai series is a high-quality aerator for flat roofs produced by the Finnish company SK-Tuote OY. The aerators are made from specially selected shock-resistant and weatherproof plastics. These characteristics make it possible to use the aerator within a wide range of temperatures, from -50ºС to +90ºС. The Alipai Aerators have proved themselves as a perfect solution in the Russian climate. We recommend to install 1 Alipai Aerator for each 80 - 100 m² of roofing.
