Fans for tunnels - Import export

The wall fans we offer are direct-driven axial fans that are easily installed in walls or ceilings. The wall fans can be in 1-phase or 3-phase design. 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, but we can also offer new impellers for existing wall fans.

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.

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 mixed-flow fan combines the advantages of axial fans with the characteristics of radial fans. Simply described, it is an axial fan with a fan wheel in radial format. This provides a cost-effective design, in duct or box design, with a stable fan curve and relatively high pressure. 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. Mixed-flow fans are usually used as ventilation fans. Typical applications are ventilation solutions in gyms, sports halls, warehouses, commercial kitchens, factories or airport terminals. Depending on requirements, the design of a mixed-flow fan can be completely adapted to the customer’s needs. With the right dimensioning and material selection, a mixed-flow fan will work problem-free for many years.

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.
