Technical appendix Rittal fan cross over — 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 – designated TopTherm – 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 TopTherm equivalent.
