Old vs. New Design – Conversion Made Easy
As with all products, Rittal continuously implements design improvements and new technology. Our entire line of filter fans has
been updated to a new design and, because they have been engineered to fit the same cut-outs as our prior fan design, they are
easily integrated into your application. The table below makes it easy to transition from the prior design to the new one.
