Centrifugal fans

The fans used in the recuperator guarantee high air efficiency and proper external static pressure.
Electronic commutation makes them easy in controlling and it ensures rotational speed stability. What is
guaranteed by such fans? These fans are characteristic for a very silent and stable operation. Their
another advantage is that they are maintenance-free. These fans do not require any cleaning, replacing
the bearings, etc. When using them, we also take care of our budget because their energy consumption is
very low.
