Here are some pictures of the HaloFX unit so you can see what it looks like from all sides. Although not shown in these images, hopefully you can image the unit being mounted to block instead of the actual physical wall. If you can have hook on the block you can hook that machine on the wall, then easily remove and hook onto a hand truck/trolley.
When mounted in the wall the unit has an adapter that feeds into the room.
When mounted on the trolley the unit has the adapter for direct attachment to the hose and mask.
