Duct shunting...

[M_C]

I've been looking about & can't seem to find what I am after... I don't even know if it is available anywhere

I want to have two intake (one from the loft & one from the room that contains the grow room) but I want to be able to shunt them so I can choose either one (don't want/need to use them both together)

I assume that the part I'm looking for is a 'Y' piece with a manual flip to swap the intakes position on the 'Y' so one part of the 'Y' stays open whilst closing off the other part?

I think the above makes sense?

...any ideas?

You could simply have two duct throttle valves on the two legs I guess.

Makes absolute sense and in the air conditioning/air movement world this does exist . I'm not sure of the name of the correct part but I do know there are available . I'm also sure face runs something very similar . If you can't find what you are looking for get me a decent drawing and I'll make it you
Two of these attached to a y pipe and then you can open and close either intake

That is pretty much what I am after.... but maybe a cheaper version
