Roof Fans TFSK/TFSR

Product catalog summary

Overview: The TFSR and TFSK roof fans are designed for use as extract fans in smaller premises such as flats, apartments, storage areas, and small workrooms. They feature a swing-out function for easy maintenance and cleaning.

Specifications: Both models are made from powder-coated galvanized sheet steel, available in black or brick red, with silver grey as a special request. The TFSR has a circular connection, while the TFSK has a square connection. They include an integrated isolation switch and a 1-meter cable for connection to a junction box.

Installation and Accessories: The fans can be speed-controlled using a 5-step transformer or a stepless thyristor. Various roof curbs and covering plates (TOS/TOB) are available to facilitate installation. The TG roof curb and SSD socket silencer are recommended for installations requiring sound attenuation.

Performance: The fans are equipped with high-quality external rotor motors and centrifugal fans with backward-curved blades for efficient operation. They offer a range of power outputs and airflow capacities, with maximum airflows ranging from 310 to 1516 m³/h depending on the model.

Technical Data: The fans operate at 230V/50Hz, with power consumption ranging from 25W to 307W. They have a maximum temperature tolerance for transported air between 40°C and 70°C, depending on the model. Sound pressure levels vary from 23 to 47 dB(A) at 4/10 meters distance.

Safety and Maintenance: The fans include a thermal contact with automatic reset to prevent motor overheating. The horizontal discharge design minimizes internal pressure losses and prevents ice accumulation on the roof. A protection guard is included to prevent accidental contact with the impeller.

TFSK For installations with square connection, the TFSK is a suitable choice. The TFSK has a square bottom plate and is fitted with an isolation switch and 1 m cable for connection to a junction box. For installations with high demands on sound attenuation in the duct, the TFSK in combination with the roof curb TG or the socket silencer SSD is a very good solution that is again easy to install. TG The brackets make it easy to fit the TG roof curb to the roof pitch. The TG is manufactured from galvanised sheet steel and insulated with a 50 mm rock wool sheet and a perforated inner plate. The roof...
