The fans have a round casing made of galvanised steel, which provides reliable protection against corrosion. The impeller with backward curved blades is mounted inside the casing. The wheel is carefully static and dynamically balanced before assembly and the fan after assembly.
The electric motor is single-phase with external rotor, which allows to regulate the impeller speed by means of speed regulators. Thermal protection of motors is realised by means of thermal contacts. Protection against overheating is realised with the use of a thermal contact that breaks the power circuit of the fan motor supply.
The design of the fans ensures straightness of the air flow passing through it. Low noise level during operation allows to use fans in premises with strictly regulated requirements on noise characteristics. The use of fans of this type allows you to create ventilation networks in conditions of limited space with the use of ...
