FLÄKTCOMP SWEDEN AB - A Leading Fan Supplier

Axial fans are a type of fan that creates airflow through a fan wheel that rotates around an axis and moves the air parallel to the axis. Axial fans can also be called propeller fans and are usually delivered as a complete unit consisting of fan wheel, motor and cover. Typically axial fans are direct driven with the impeller mounted on the motor shaft. There are also other designs such as e.g. belt-driven or with shaft bearing and coupling. The axial fan’s strength is to transport large volume flows at low pressures. At higher pressures, a centrifugal fan may be a better choice. To reach higher pressures with axial fans, these can be connected in series. Usually, the efficiency of an axial fan is comparatively lower than that of a centrifugal fan. But by using guide rails, diffusers and other accessories, an axial fan can reach the same or higher efficiency. The flow of axial fans can be regulated with vane or damper or speed regulation.

Radial fans or centrifugal fans are a type of fan that uses centrifugal force to create a pressure increase and a volume flow. This type consists of a fan wheel that rotates in a snail-shaped cover. The flow enters the fan through an inlet placed axially with the fan wheel shaft and motor, and is then thrown out radially with the help of the force from the fan wheel. Unlike axial fans, the motor is not in the volume flow of radial fans. To change the performance and characteristics of centrifugal fans, different designs are used on the fan wheel. The strength of the centrifugal fan is its versatility. A radial fan can be designed to transport a variety of volume flows at a wide range of pressures. At higher flows and relatively low pressures, an axial fan may be a better option. Centrifugal fans are available in single and double suction versions.

A flue gas fan is a fan that usually has the task of extracting flue gases from an industrial application, e.g. a melting furnace or pan. Flue gas fans are almost exclusively radial fans and transport not only clean air but also flue gases up to 550° C continuously. Flue gas fans are often a very important component in an industrial system. Our many years of experience and large product range give our customers peace of mind. Development. design and manufacture of fans for flue gas takes place with the highest precision and with the highest quality materials. In order to choose the right flue gas fan, one should start from operating data and system design, as well as whether there are any special requirements.

An Impulse fans (Jet fan) ísa a type of axial fan that is adapted for operation in tunnel environments by e.g. material selection and silencer. The tunnel fans create airflow through a fan wheel that rotates and moves the air axially. They are usually delivered as a complete unit consisting of fan wheel, motor, cover, silencer and mounting stand. The flow of tunnel fans can be regulated with a frequency converter. In order to choose the right impulse fan for tunnel ventilation, one should start from operating data, tunnel design and whether there are any special requirements.
