Ventilation with type N.Tesla motors
Dospel was the first company in the world to create groundbreaking ventilation, the heart of which is an energy-saving N.Tesla type engine.
Industrial roof ventilation fans
Dospel roof fans are used to remove air from production halls, warehouses, commercial pavilions, shops, offices, single-family buildings, i.e. devices designed to ventilate large rooms. All three types Roof fans are intended for supply and exhaust ventilation. They can be used both indoors public buildings (restaurants, bars), sanitary rooms, residential premises and industrial facilities. The advantage of the WD II series fans is horizontal air discharge, which prevents it from returning to the building.
