ventilators: venture industries: duct fans

The high pressure and efficiency achieved allow the use of these fans in all types of ventilation installations. The compact casing, makes fans of this type have all the advantages of axial fans, surpassing them with the parameters achieved. This allows for overcoming large resistance of installations created in small diameter channels and trouble-free cooperation with filters and duct heaters. TD SILENT fans are characterized by low height, thanks to which they are recommended for mounting in suspended ceilings. Ideal for ventilation of public buildings, libraries, conference rooms, offices, restaurants, classrooms, sound studios.

Construction

Duct fan designed for ventilation of rooms with a low degree of dust, adapted for mounting in a vertical or horizontal position in ventilation ducts with diameters from 100 to 200 mm. The unique design allows you to achieve high pressures and performance at a minimum noise level.
The original design allows maintenance without dismantling the ventilation ducts. TD SILENT housings are made of polypropylene, while ABS plastic impellers. Thanks to the innovative design solutions characteristic of “Silent-S & P” technology (including anti-vibration mounts of the engine, aerodynamic interior geometry, integrated internal silencers), they are characterized by low noise and vibrations. The fan connections are equipped with elastic couplings with quick couplers – “Quick-fix” bands – allowing the fan to be installed in the duct without the use of tools.

Electric engine

TD SILENT fans are equipped with single-phase (220-240V, 50Hz) induction cage motors (models 250, 350) and single-phase motors (220-240V, 50Hz) with an external rotor (models 500, 800, 1000), compliant with UNE 20- standards 113 and IEC 34-1 with protection degree IP44 and insulation class of the winding B. Motors equipped with bearings. All motors suitable for voltage speed control. TD SILENT fans are equipped with two-speed motors as standard, designed to work in two rotational speeds. All motors have thermal protection of the winding against overloading – fuse in 250 and 350 models and automatic fuse in other models.
The design of the compact junction box allows you to connect the power cord from any side – 360°.
