All right, so this is the inside of a buy flow dryer. This is a solid core. Sporeline, reversible catch-all got a seal, we've got our valve here and then you have a metal mesh and then this kind of cloth screen, but how the main thing i want to show here is that when it's going this direction when flow's coming this direction, it opens Here the refrigerant flows around and then travels through from the outside in and then it opens up our valve here i mean this has like no resistance at all. It won't allow flow to come back the opposite direction this way, and so, if flow is coming, the opposite way, it's going to do the same thing it's going to flow in around these little holes on the outside, so these open really easy.

It's going to flow around the outside come through, go through and then come out, so it filters the same. Both ways that is your good old-fashioned standard catch-all by flow filter, dryer, pretty cool.
