A canister on its side will allow waste gases to travel across the top limiting its effectiveness while a canister on a table will block the waste gases from exiting. The vertical canister holder accepts any canister that's 3" dia. or smaller. Model #FC-A is included and connects standard 1/4" tubing to the canister. The vertical holder is for passive systems only and can be tabletop or wall mountable. See model number FC-A for 90 degree adapter only.
