Installation of mechanical ventilation and assembly tips

In this expert article we talk you through the dos and don'ts of installing a mechanical fan yourself. Many of these tips can, of course, also be used when connecting other, similar, fans.

Can I install a mechanical fan?
Yes, this is possible. With every mechanical fan we provide an installation manual to make it as easy as possible for you. We advise you to take it into account if you purchase a fan with a perilex plug. You can read more about this below.

Installation position of a mechanical fan

A mechanical fan has the major advantage that you can install it in different positions. This can be placed against the ceiling, wall, sloping wall and even on the ground. These positions give you a high degree of flexibility in terms of installation.

When installing, always take into account the fan's air outlet duct. Each mechanical fan always has one outlet. Usually the fan box is installed with the air outlet facing outwards.

For your information
When you purchase a mechanical ventilation system, two connections are always either not fitted with a cover or not sealed. The reason is that there must be one outlet and one extraction opening at all times.

Application of sound absorbers

The installation of sound absorbers for an MV is very common and recommended. The most commonly used sound absorbers are flexible sound absorbers with a diameter of 127 mm or the acoustically insulated ventilation hose, available as 1 metre, 5 metre and 10 metre versions. These dampers attenuate the sound of air movement directly from the fan and the resonance of the ventilation system itself. If you have the possibility, we always recommend a minimum length of 1 metre per connection. Would you like to attenuate the sound even more at the valve itself? Use the Inno dampers.

Having a mechanical valve installed

If you can't find your way out or if you want to clean the channels, please contact us to see what we can do for you.

Four general assembly and installation tips when installing a fan

1. Location

When installing a new fan (no replacement), first assess whether there is sufficient space to install a fan. Take into account the length, width, height and depth of the fan, as well as any pipe and electrical connections and, in the case of heat recovery, the condensation drain.

2. Specifications

When replacing a product, it is important to know in advance what the properties of the old product to be replaced are. Why? Because after purchase you will always have a product that fits your needs. For example: connection diameters, length, width, height and depth, but also the electrical connection (perilex, earthed or euro plug).

3. Manuals and assembly videos

Most manufacturers send a (installation) manual with the product. However, we recommend that you read the installation manual before purchasing in order to answer any questions or to prepare for installation. Then use our data enrichment. We have added (installation) manuals and/or brochures to 99% of all fans. These are .pdf files and can be downloaded directly from our website. These files can be found on the product pages under the heading "documents". If you prefer to watch a product video, please click here.

4. Safety

Last but not least, safety is the most important issue during installation. Installing a fan, with safe products, in a safe environment. Here are the three most important points:

• Before making any electrical connections, switch off the power/electricity
• Do you need to install the fan at height? Use scaffolding or sturdy stairs, always make sure to use a flat, non-slippery surface
• Work with certified/well-working tools
