AIR VENT DEFLECTOR SIDEWAYS INSTALL

When trying to install your pop up floor register, it only takes one step drop it into your floor opening and you are done! To install the plastic air vent over into your wall or ceiling, you simply use the knock out screw holes on the ends of the register to mount.

Because these are plastic air vent covers, you will never have to worry about rust or scratch marks from appearing onto the faceplate. These pop up floor registers are constructed from polystyrene that is made for high impact. The plastic air vent cover has a small louver on top to slide the register into an open of closed position. Our pop-up floor register can be used as a traditional heating and cooling register or as a deflector for your airflow. The plastic air vent cover comes in two sizes and can be used on the floor, wall or ceiling. This pop up floor register is truly one of a kind since it can diffuse your airflow from the top of the register or it will pop-up to deflect it forward. The takeaway lesson here is that trunk-and-branch duct systems should have no vents at the end of the trunk line (the end cap).Pop Up Floor Register - Plastic Air Vent Cover The room may end up with negative pressure, thus pulling in unconditioned air, with all its heat and humidity or freezing coldness. If they’re unlucky, the so-called supply vent actually sucks air out of the room. If those three vents actually serve different rooms, one room is going to get way too much air while the other two actually get no conditioned air…if they’re lucky. In the diagram above, you can see this principle illustrated. With a moving air stream that’s all heading for a grand exit at the end of the tunnel, any branches off to the side may actually cause air to move in the opposite direction that the duct design calls for. If that air gets to the end of the line and finds nothing to stop it, most or all of it will go straight out the end.Įven worse, there’s this little sciencey thing called Bernoulli’s Principle, which says that the pressure is lower in a moving air stream than in still air.

The blower is pushing air down that big duct. What’s the flaw? See that vent on the very end of the trunk line? That absolutely should not be there. (Of course, it may be more likely that you have a ductopus in your home.) It’s possible, though, that you have a supply trunk line in your attic or crawl space or basement, and if it has the same kind of problem shown above, you may have rooms that don’t get enough air from the air conditioner, heat pump, or furnace. They’re also all in the same room, and that’s why the flaw here doesn’t really create a distribution problem in this case. In this case, it’s a commercial application with an exposed duct, and all the vents are just cut right into the trunk line itself. Can you spot it?įirst of all, this is a supply duct trunk line, which sends the conditioned air out to the rooms that need to be heated or cooled. Well, it’s not fatal in this application, but it can certainly lead to air flow problems. You may not be aware, but this duct design has a fatal flaw. When I was up in North Carolina this past summer, I went to a restaurant that had the duct you see in the photo here.
