Questions and answers of the customers
-
I have a portable air-conditioning unit, ducts through the roof, I use the same duct when not to hot to suck in outside air with a pump off a t bend - 1 side goes to aircon, other ducts into room through an in line fan
I want to block this off when I am blowing air out in the the other side. This valve would be fine, but can I connect it in line to 100mm plastic pipe?
