What air flow capacity AAV?

[Cooop]

Refurbing my ensuite and replacing the 20 year old AAV. What air flow capacity do I need? Its for a toilet, sink and shower. Nothing else is on that stack on that side of the house.

McApline VP100 (42.7 l/sec) or VP50 (15.5 l/sec)?

Is the stack 110mm? If so go for the VP100.

 

[Cooop]

Yes, but they both fit a 75mm or 110mm pipe so I was confused
