Fans - circular duct

Fans - circular duct

Circular duct fans are suitable for central ventilation of commercial buildings, family houses, sanitary facilities or workshops. In the category of circular duct fans there are all types of fans - axial, radial, diagonal - which have a neck in circular diameter. The best-selling types for residential buildings are the TD Silent, the TD Mixvent and RVK fans, which thanks to their plastic construction achieve very favourable noise parameters. For industrial applications with relatively higher pressure loss, the RM or KD fans are most often used.

TD Silent

TD Silent

The TD Silent noiseless diagonal duct fans are intended for installation to circular ducting. For TD Silent 160-1000 types, the fan housing is made of high-quality ductile plastic. In case of sizes TD Silent 1300 and 2000, the housing is made of high-quality galvanized sheet metal.

The smallest version of the TD Silent fan (160/100) has a motor mounted in elastic blocks, greatly reducing vibration and noise. The 250-1000 fans are equipped with a patented vector noise absorber (see the construction picture). For the TD Silent 1300 and 2000 types, the housing includes glass fibre sound insulation as well as an aerodynamic solution of the intake side, which ensures an exceptional reduction of noise levels.

The terminal block can be rotated 360° (types 250-1000) and thus allows cable connection from any direction. The easily removable TD Silent fan motor unit is mounted in an integrated assembly console for easy wall or ceiling installation. The fan speed can be controlled by two-stage speed switches (2 motor windings) for standard versions, versions (3V) have 3 power levels, versions with timer (T) and all others can be controlled by electronic REB rotational speed regulators.

 

TD Mixvent

TD Mixvent

The TD Mixvent diagonal duct fans are designed for installation in circular ducts. The fan housing for types 160-800 is made of high-quality tough polypropylene. In the case of the sizes 1000 to 6000, the housing is made of high-quality galvanized sheet metal and is provided with an epoxy coating.

We supply the TD Mixvent duct fans in a standard design with resistance of up to 40 °C, 60 °C from the size of 200 mm. The currently available 3V version of the TD Mixvent series provides an air flow volume range from 180 to approx. 5,000 m3/hour.

The TD fans are also available in a variant with an integrated overrun timer (marked "T") without the possibility of control.
The variants without markings have two speeds, the 3V can be controlled by a 3-stage controller.

The TD Mixvent fans can be installed in a horizontal or vertical position. The unique design of the support bracket allows mounting or dismantling of the motor and impeller assembly without dismantling the ducting. The TD Mixvent fans have motors with greased-for-life ball bearings. The TD Mixvent fans include a mounting bracket that allows them to be easily attached. The installation and service of the TD Mixvent motors is efficient and fast.
