Centrifugal fans come in a variety of designs, adapted to different applications.
The range of our centrifugal fans is adapted to meet most combinations of volume flow and pressure using direct drive fans.
As the fan range is based on a modular system, the majority of fans can be manufactured from standard components. This enables short lead times and competitive prices.
In addition to standard fans, we also manufacture a large number of special designs, according to your needs.
Below is an overview of our standard range of centrifugal fans.
Design 1 (3d and 6d)
It is often advantageous to aim for a direct-driven fan. It is more compact, has fewer parts and is in most cases cheaper than other designs.
We offer 3 different designs with direct drive. Designs 3d and 6d differ from design 1 in that they are pivotable and the impeller can be removed from both sides.
A flange-mounted motor makes design 6d lighter and more compact.
Design 2
At higher speeds that cannot be achieved with a direct drive motor is required, or if there are other installation-specific requirements, a fan with belt drive is used.
Mounting of the motor takes place in a number of different ways.
For design 2, the fan and motor are mounted on a common base.
Design 2a is the same construction but with a rotatable casing and a fan wheel that can be dismantled on both sides.
Design 2b has the motor mounted on the side of the pedestal to achieve a more compact design.
Design 2c is for small motors.
Here the motor is mounted inside the pedestal with an external junction box. Although this design is more difficult to service, it is the most compact belt drive and less expensive than the other belt drive options.
Design 4
Design 4 is a complete unit where the motor with belt drive is mounted directly on the fan cover. When a compact design is needed, design 4 offers an interesting alternative. However, relatively extensive reinforcements of the fan cover are often required.
Design 5
Today it is relatively common for fans to be equipped with an elastic coupling. It can e.g. be in applications with high temperatures.
An elastic coupling also makes it possible to dampen and protect the motor in tougher applications that require high starting torques or variable torques such as in e.g. material transport.
