Application
Roof exhaust fans RF / EC are intended for room ventilation with low air pollution. They are used, among others, in:
   • building exhaust systems residential, supermarkets,
   • industrial halls, workshops, warehouses, toilets,
   • garages, parking lots, farm buildings and others.
Construction
   • rotors with backward curved blades, made of plastic,
   • base, upper bowl and others elements are made of aluminum sheet,
   • galvanized protective mesh,
   • adapted to work in a vertical position,
   • installation on flat roofs,
   • maximum working temperature +60°C (depending on the model).
Motor
   • single-phase power supply 230V, 50Hz or three-phase 400V, 50Hz,
   • highly efficient motors with integrated EC technology,
   • 0-10V DC control input,
   • smooth speed control,
   • insulation class B, protection class IP44 (models 125 / L, 125 / H, 160 / L and 250 / L),
   • insulation class F, protection class IP54 (models 125 / E, 160 / H, 200, 250 / H, 315S,           315T, 355T, 400T, 450T and 500T),
   • degree of protection IP44 (models 125 / L, 125 / H, 160 / L and 250 / L),
   • degree of protection IP54
