How I added some quiet air circulation to a room with no vents.
Right after painting my room in the new house I realized that it did not have a vent. This became problematic as the room had absolutely no air circulation if the door was kept shut.
Since the rooms adjacent to this one had no occupants I decided to do the easiest thing and just punch a hole through the walls, frame it in with two-by-fours and put a grille on either side. This helped a bit, but the air was still not being pushed through even with the door closed on the neighbouring room. So I decided to add a few case fans. With the silicone washers between them and the grille, the fans are practically inaudible running at their max 12V and now the air is flowing nicely through the room. The fans also only draw 80mA each, meaning the whole thing uses less than 2 Watts.
-
- The first step was to cut a hole in the wall using a drywall saw and a couple of 2 by 4s to frame in the hole.
-
- This is a regular air return grille. I drilled a couple holes for the fan with the drill press
-
- Fans were bolted on with silicone washers between the fan and the grille
-
- Wires for the fans ready to be soldered together
-
- Wires are soldered to a strand of two conductor white 18AWG wire
-
- Fans are mounted in the hole. the drywall screws around the outside edges are to hold the 2 by 4 framing
-
- Here it is with the front grille on and the wire down the wall
-
- I also picked up a 12V white led strip from amazon. Using a plastic enclosure with a few holes drilled I glued in a switch and a plug for the power supply
-
- Here all the wires are connected. The white wire goes to the fans and is always powered, the led strip comes out the other side and is separated from power by the switch. All connections were thoroughly taped up before closing the box
-
- The lights and fan work
-
- The light strip is run along the top and sides of the closet door.
