Selection Software 

To help you choose the correct product for your application we have a choice of computer aided selection tools to enable the rapid but accurate choice of solutions.


- Selectair is our product selection software for extractor fans.

Airflow Selectair selection software allows you to select products from our Domestic, Commercial and Industrial fan ranges and also select from our Heat Recovery range suitable for your application. The software is hosted within the Airflow website.

Selectair software has been designed to ensure that products are selected to fulfil the requirements of your application. By following a logical and easy to use sequence, fans are listed which are suitable for the room of your choice, through the wall or ducted installation and the type of ducting you will be using. By automatically calculating the pressure drop values for your requirement, a choice of products are linked to ensure “installed performance” criteria is met. This gives the specifier the confidence to know that choosing a fan from the products offered will deliver the performance expected to meet the latest building regulations for fast, effective ventilation.
