Application

Exhaust ventilation of warehouses, shop and industrial halls, farm buildings in agriculture, etc. Due to the high temperature resistance, they are recommended especially as extractors from over grates, from hoods in the meat industry and gastronomy.

Construction

Roof fan designed for continuous operation with a medium with a temperature of 120 ° C. The fans have a base made of galvanized sheet. Aluminum sheet housing. The outer casing and the engine compartment are insulated with a 30mm thick mat in A1 flammability class (non-flammable).

The rotor is made of steel, ensuring durability and adequate temperature resistance. The fan is equipped with a service switch as standard. The electric motors used allow for external speed control.

Motor

Electric motor made in accordance with the applicable Directives and efficiency classes, marked with the CE mark. Insulation class - F. Protection degree - IP 55.

Power supply - three-phase 230 / 400V 50Hz, 400V 50Hz, 400 / 690V 50Hz or single-phase 230V 50Hz (depending on the fan model and motor power).
