Systemair TFSR 160 EC Sileo Black Roof Ventilator Black, 76869

TFSR-EC and TFSK-EC are roof-mounted fans equipped with EC motors designed for air extraction from small spaces such as apartments, warehouses, small workshops, etc. EC technology is an intelligent technology that uses integrated electronic control to ensure that the motor always operates at optimal load. EC motors have high energy-saving potential not only at full load but especially at partial load, where efficiency losses are much lower than with asynchronous motors.

Fans are supplied with a potentiometer (0-10V) that allows easy selection of the required operating point. The insulation switch is integrated, and various types of roof boxes are available as accessories. The opening mechanism facilitates maintenance. To protect the motor from overheating, the fans are equipped with thermal contacts with automatic restart.

TFSR EC series fans have a round connection, while TFSK EC series fans have a square connection. Horizontal air discharge reduces internal pressure losses and prevents ice formation on the roof. The protective grille prevents contact with the fan impeller. Both models are supplied with a connection box.

TFSR fans are supplied with an attachment for direct connection to the air duct. The TFSR 125-160 fan has a flange with a diameter of Ø 160, and the TFSR 200-315 fans have a flange with a diameter of Ø 200. The flange is not pre-mounted on the fan.

In cold climate zones, it is recommended to use the fan continuously to avoid icing problems. In the case of installation of the FSD-L flat roof box, the TDA adapter is required.
