How to select the correct fan

How to work out the size and type of fan required:

In order to provide adequate ventilation for a given application, it is essential the
correct size, type and number of Hydor units are selected. Selection of the correct fan depends on two
principal factors: the performance and application.

Step 1

Determine which mounting arrangements meet your requirements

Step 2

Calculate the VOLUME of the room in cubic metres (m³) by multiplying the length x width x height.

Step 3

Select the type of room from the AIR CHANGE GUIDE and how many air changes (AC/H) are required.

Step 4

Use the following formula: Volume (m³) x AC/H = Airflow (m3/h)

Step 5

Use the catalogue to select a fan that does the airflow you require.
