When inline fan is in operation air from both washrooms will vent out.
Can you run two bathroom fans together.
The classic example occurs in multifamily units if one tenant is a smoker the tenant next door can smell tobacco smoke that enters the bathroom through the exhaust fan.
It is basically a fan in a box with 3 to 4 ports on the side.
You d often blow air from one bathroom into the other and local building inspectors wouldn t approve it.
The typical problem is that odors can migrate from one bathroom to another.
Both washrooms must have nearly identical square.
Was replacing bathroom fan 1 and while it was disconnected from its duct pipe the fan in the bathroom 2 was on and.
An additional option is to use the cvs series fan from fantech.
If you have two bathrooms that are close together and one has an exhaust fan and the other doesn t you might be wondering if you can tie a new exhaust duct into the existing one.
The 2 fans have their own ducts but just before they vent out the roof their duct pipes are attached to a common duct upside down y which means they vent out the same hole in.
Connecting bath exhaust ducts together can result in problems.
I plan to add a fan to the other bathroom but want to avoid drilling a hole in my roof.
I have two adjacent bathrooms one of which has an exhaust fan that vents through the roof.
I vote to keep the ducts separate.
You can replace the fan opening with a grill for each washroom.
Then add an inline fan to the remaining leg of the y adapter and run ducting to vent outside.
The above scenario will work provided the following.
