IBF fans are used in a variety of mechanical ventilation systems, combining the benefits of axial fans - flow direction and radial - stable compressibility, low noise level, high efficiency. Examples of applications include supply and exhaust ventilation of flats, offices, shops, bars, cafes, restaurants.
Duct fans designed for mounting in any position in rectangular ventilation ducts. Housing made of galvanized sheet steel. Fitted with mounting flanges on the inlet and outlet side. Flap for access to rotor and motor without dismantling the installation.
Rotors with sloping backward vanes are adapted to transport the maximum amount of air at high static pressure with minimal noise. Rotors, depending on the size of the device, are made of plastic or aluminium sheet (depending on the model). On request, fans can be made in any colour of the RAL palette.
Single-phase 230V, 50Hz or three-phase 400V, 50Hz induction motor with external rotor. Motors adapted for smooth rotation speed control.
The motor windings have thermal overload protection. Operating temperature -40oC to +70oC, depending on model.
