ATEX fan

A fan designed for material transport is often a centrifugal fan with an impeller adapted for abrasive particles in the air flow. Fans that transport different materials in the air flow are often extra robust fans, with the right material in the cover and fan wheel. Depending on the application, the fan wheels can be equipped with knives that not only beat but also cut the transported material into smaller pieces, this type of fan is called a knife fan. By developing a fan for your particular application, we ensure that the fan can perform over time – regardless of how tough the application is. With a durable design with a stable fan curve, we know that our fans for material transport can help you with your particular application. Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans takes place with the highest precision and with the highest quality materials.

A roof fan can be the same name referring to two different types of fans. On the one hand, it is the classic fan that is mounted indoors in homes and spins around to create an air flow in a room (these are also called HVLS fans (High-Volume Low-Speed)). And partly it is the type of fans that we work with – i.e. fans that are mounted outdoors on roofs belonging to e.g. apartment buildings, schools or industrial premises. A roof fan is a fan that is part of the ventilation system and has the task of extracting hot air, moisture and pollution from the indoor space and blowing them outside. The fans are usually designed to be robust and weather resistant as they are mounted on the roof. Of course, there are a variety of material designs adapted to the application needs.

Renewable energy sources are something that is becoming more relevant every day. Biogas is an alternative and here FläktComp Sweden can contribute with high-quality fans that ensure that the biogas is handled correctly. Biogas fans are a type of gas-tight radial fan, adapted for use in biogas environments where the demands on materials and performance are very high. The fans are usually delivered as a complete unit consisting of fan wheel, motor, cover and vibration feet. In order to choose the right biogas fan, one should start from operating data and process design, as well as whether there are any special requirements.

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.
