When we talk about filter fan units for electrical panels, we must keep in mind the main function for which they are designed: to produce an air flow sufficient to cool the electrical panel, with a slight overpressure compared to the installation environment. But sometimes, just one fan filter is not enough: how to install them? Is it more appropriate for them to be in series or in parallel?
If you want to know more, read our #whitepaper on fan filter unit in series and in parallel.
The attached White Paper will give you precise indications on how to find the working point and calculate the global characteristic curve of the fan filter groups.
