Welcome to our range of inline fans at Sub Floor fans warehouse. The Inline fans we sell can be split into three categories:
Centrifugal Fan: This is the most popular choice for sub floor installation as the fan performs very well over long duct runs. This means that it will retain its capacity much more than any other type of fan. For this reason we sell centrifugal fans with our pre packaged kits.
Mixed Flow: These fans display centrifugal characteristics in sizes of 150mm and above and are generally recommended for moderate lengths of ducting.
Axial: Only really appropriate for short duct runs.
Each fan has a 'AREA UP TO XX' size rating – this is based on achieving 5 air changes per hour (this is the standard recommendation for air changes to ventilate a sub floor area).
