Fläkt Woods Group SA STOF ROOF EXTRACTION UNIT

The STOF is available in 3 versions: Vertical, Horizontal and Horizontal Shutter. The key purpose of the STOF range is to provide a more compact, energy efficient roof unit with the market. Due to this the STOF applies itself well to the refurbishment market as well as new customers. Should a customer wish for a larger STOF unit an adapter plate can be provided to make the installation as easy as possible. Fans are suitable for different roof curb mounting using an installation frame or can be fitted directly to roof base. The motor is a single phase, AC external rotor motor with speed control. All STOF models come in 8 standard sizes. The models have a very low profile making them easy to install and aesthetically pleasing and convenient for consultants and end users. The STOF motorised impeller has been designed to meet 2015 ErP Compliance legislation which makes them ideal for replacing existing roof units that may potentially fail to meet ErP criteria from 2015 onwards
