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 duct ventilation fans
The groundbreaking duct fans with an N.Tesla engine by Dospel are designed for installation directly in ventilation systems. Possible operation as supply and exhaust, depending on the direction of fan installation.
