Description
The Systemair TFSR range comprises roof fans featuring a circular base plate and a single-inlet centrifugal fan with backward-curved blades and external rotor motors. The motors are designed to tilt outwards for easy inspection and service. They include an integral on/off switch and are supplied with a 1-meter cable for quick connection to the mains, such as via the connection box on the roof curb TOB or TOS.
These fans are suitable for exhaust-air ventilation systems in various applications, including single and multiple dwellings, offices, and day nurseries. To protect the motors from overheating, all motors are equipped with an integral thermal contact featuring automatic reset. The fan casings are constructed from galvanized steel and finished with a powder coating in black.
Models TFSR 125-160 are delivered with a Ø 160 spigot, while TFSR 200-315 models come with a Ø 200 spigot. For cold climates, it is recommended to run the fan continuously to prevent issues with ice formation.

Performance and Efficiency Data
Performance Curves
The document includes two performance graphs. The first graph plots static pressure (Pstat) in Pascals (Pa) on the vertical axis against airflow (Q) in cubic meters per second (m³/s) on the horizontal axis, showing multiple performance curves. The second graph plots power consumption (P) in Watts (W) on the vertical axis against airflow (Q) in m³/s on the horizontal axis, also displaying multiple curves.
