Question about Broan-NuTone N-LS100SE Exhaust Fan Exhaust Fan
I have a bathroom vent. I just installed another similar vent in my closet and when I was in the attic I noticed the ducts from both are quite close next to each other. Both of them use 4" ducts and I'd rather not cut another hole in the roof. I know 100% that the new vent has a flap to prevent air back flow. I have not checked the bathroom vent but it's only couple of years old and I assume it has the same. I was wondering if it is possible to connect both ducts to the same vent in the roof, perhaps by using some y-connector. Are there any cons or pros? Is it in compliance with whatever codes that govern ventilation?
U should increase the size of vent,if both fans runs the same time

If it JUST a vent, then it would be fine. The VENT only allows air to move and is Not pressurized. If it is in fact a vent "fan", like in most bathrooms, then it will still work but for best results, you should Not have both fans running at the same time due to CFM of air being pushed through the 4" opening , it will be trying to accommodate twice the volume as intended/designed for.
