The title literally says it all. My tent (Aviditi PTU-67 48x24x60) has 4" holes for ventilation to attach into. I need to modify the tent to allow for 6" ducting. This would increase airflow, decrease turbulence noise, and decrease the level of fan power needed. How should I go about doing this, without messing up the tent? I know it has been done before. Should I just have at it with some scissors? Or should I just use 6-->4" adaptors in and out? I dont want to cut it if doing so will result in the tent tearing. All thoughts appreciated!
If you take a object that is 6" in diameter and center it over the pre-existing 4" hole and then trace out the shape with a marker and then cut it out with some scissors, you should be okay. Using reducers bottleneck your system and any benefit gained from having the larger system will be lost.
I'm actually more concerned with noise. My thought is easier / more airflow means the fan does not have to work as hard and achieves the same result. The issue is that the tent has duct slots, and not just holes for the intake / exhaust. Especially in the case of the exhaust on top, it curves so that I can attach the filter horizontally. I think for the intake a hole is just fine, I would just need duct tape or something to seal air / light leaks. Edit*: I just realised that I can probably just make relief cuts in the tent's duct slots, so I dont have to remove any material. I would then use duct tape to keep it airtight. Or is there another better material? Pic to help explain: Sorry about the size... hopefully no1 is trying to read from GC mobile :S
