Hello everyone,
for our construction project, the Zehnder Comfoair 350 is to be installed. The catalog offers two different duct systems to choose from – on the one hand the InFloor system, where round flexible ducts are used, which are integrated into the concrete ceiling, and on the other hand the OnFloor system, where flat-oval flexible ducts are used, which are integrated between the concrete ceiling and the insulation layer.
I once read somewhere that the round ducts are the better alternative because they achieve optimal flow behavior and the air resistance is lowest here.
The general contractor also initially promoted the round ducts, but now suddenly the flat-oval ducts are to be installed... a bit strange.
Does anyone have experience with this OnFloor system? Are there increased flow noises during the operation of the ventilation system due to higher air resistance here, which perhaps already fall into a range that is perceived as disturbing? Or maybe someone has another ventilation system with flat ducts and can say something about it?
