STEF HT roof fans run quietly, they are easy to install and service and are available with speed control. Naturally, they are very efficient providing airflows up to 5 m³/s. A roof fan is there to provide the comfort you expect. It must also function without generating unnecessary noise that can disturb those nearby. This is one of the features that we have focused on with the Roofmaster STEFHT. The Fan casing has been amply insulated. The Fan impeller has been “streamlined” to generate less sound. The Roofmaster has a very stable design which prevents unnecessary sound emission. In addition, the fan speed can be controlled which implies that the fan need never run faster which allows the fan to be used for demand ventilation. Real comfort is determined not only by low sound emission and good air quality, it is also influenced by the visual impression that the roof fan conveys. The Roofmaster has been designed to be well suited for installation in most types of roof structures.
