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.

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.

ATEX fans are fans that are installed in environments where there is a risk that an explosive atmosphere can form. Therefore, these fans need to be designed according to the ATEX directives. Depending on the classification of the environment, internal solutions inside the fan, such as e.g. spark protection in the fan cover or non-sparking materials. While in other cases, EX-rated motors are also required. Explosive gases require special fans. Our factories are certified according to ATEX for the manufacture of fans for Zone 1 and 2 as well as for Zone 21 and 22 containing dust. The design, production and use of fans for explosive media or environment is clearly specified in Europe by standardized directives. To choose the right ATEX fan, one should start from operating data and process design, as well as whether there are any special requirements.

In tough applications such as e.g. high temperatures or movement of corrosive gases, it is not always possible to mount a motor in the volume flow. The solution for this is the so-called bifurcated fan which is an axial fan where the air flow is divided in a tunnel, which means that the motor is not in the volume stream. It is thereby protected from possible harmful particles or high temperatures. 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. The fans are usually supplied as a complete unit.

A smoke fan is a fan whose task is to operate under extreme heat conditions, usually in the event of a fire. Smoke fans are a very important part of many of today’s safety systems in tunnels and buildings. There are a variety of standards that smoke fans are classified within, it can e.g. be F200 Classification for operation at 200° C for 2 hours F300 Classification for operation at 300° C for 2 hours F400 Classification for operation at 400° C for 2 hours Our many years of experience and large product range give our customers peace of mind. Development, design and manufacture of fans for smoke gas is done with the highest precision and with the highest quality materials. A smoke fan can be designed as an axial fan or impulse fan. To choose the right smoke fan, you should start from operating data and system design, as well as whether there are any special requirements.

Garage fans is a collective name for the different types of fans used for ventilation of underground parking garages. Often, ventilation systems in garages are made up of classic duct systems. Instead, we offer complete systems with impulse fans for garage ventilation. Functions and advantages of impulse and induction systems compared to traditional duct systems: Easier and faster installation Lower construction costs Less maintenance Airier feeling (fewer things on the roof) Our many years of experience and large product range give our customers peace of mind. Development. the design and manufacture of fans for garage ventilation is carried out with the highest precision and with the highest quality materials. The fans are usually delivered as a complete ventilation system consisting of all fans, control units and other accessories.

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.
