Duct fan designed for ventilation of rooms with low dustiness. Adapted for mounting in vertical or horizontal position in ventilation ducts with diameters from 100 to 400 mm. It is used as exhaust and supply ventilation of flats, offices, shop, catering facilities and in cooperation with domestic kitchen hoods equipped with grease filters.

Construction

• unique design thanks to which high pressure and efficiency can be achieved with minimal noise
• The design allows maintenance without having to dismantle the ventilation duct
• two-stage TDx2 models consist of two single-stage modules in TD on a common mounting frame
• TDx2 models available in standard diameters from 125 to 250 mm
• polypropylene housing (models 160, 250, 350, 500, 800)
• casing made of steel sheet painted with epoxy paint (models 1000, 1300, 2000, 4000, 6000)
• impellers made of ABS plastic (models 160, 250, 350, 500, 800, 800N)
• impellers made of aluminum sheet (models 1000, 1300, 2000, 4000, 6000)

Electric engine

• TD fans equipped with single-phase (220-240 V / 50 Hz) induction squirrel cage motors (models 160, 250, 350) and single-phase (220-240 V / 50 Hz) with an external rotor (models 500, 800, 1000, 1300, 2000 , 4000, 6000), in accordance with UNE 20-113 and IEC 34-1 standards
• ball bearings
• for voltage speed control
• degree of protection IP44, winding insulation class B (models 160-2000)
• IP54 protection class, winding insulation class F (models 4000 and 6000)
• equipped as standard with two-speed engines adapted to work at two speeds (from 160 to 2000)
• winding protection against overload: fuses (models 160, 250 and 350); automatic fuse (other models)
