in line duct-fan IBF I

Application
IBF-I fans are used in a variety of mechanical
ventilation installations, combining the advantages
of axial fans – direction flow and radial -
stable pressure, low noise level, high efficiency.
Examples of applications are supply ventilation
and exhaust:
   • apartments,
   • offices, shops, bars, cafes, restaurants.
Construction
   • housing made of galvanized steel sheet
   with sound insulation, class A1 fire resistance,
   50mm thick,
   • flanges on the inlet and outlet sides assembly,
   • inspection hatch,
   • rotors with backward curved blades,
   • rotors are made of plastic or aluminum sheet
   (depending on the model),
   • working temperature -40°C + 70°C
   (depending on the model),
   • installation in any rectangular position
   ventilation ducts.
Electric motor
   • asynchronous, single-phase 230V 50Hz 
   with external rotor,
   • asynchronous, three-phase 400V, 50Hz
   with external rotor,
   • thermal protection against overload,
   • for voltage regulation (single-phase motors),
   • for frequency control (three-phase motors).
Special versions
   • painting in a color other than the standard,
   • painting in a higher corrosivity category.
