How many of these kits will i need to make 3 complete boxes?

Asked by john August 17, 2020

Answers

Each of these plenum kits have one open side to attach to a piece of HVAC equipment, if you are looking to make 3 "boxes" with no openings you would need to purchase 1 extra plenum kit, for a total of 4 kits. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

Can this be used in my attic as the central return box for my return air? I have flex duct returns in attic.

Asked by Mark January 19, 2019

Answers

Yes, it can be used as you are describing. This is typically used to attach to the air handler as return air plenum although it can be used to connect returns in the attic as a "mixing box" before attaching to the furnace. If you have any other inquiries about our Master Flow products please call Technical Services at 800-211-9612.

I've made a nice trapezoid
I purchased this 24x24" pre fab duct board plenum kit to save time and do the job quickly. I special ordered this kit, and while it arrived for pick up within a week, I was confused to find incorrect/unfinished shiplap edges on the panels. Against my better judgement I followed the mediocre instructions on the packaging, and ended up with an oblong, trapezoid shaped box closer to dimensions of 23x25." I hope this is an error in my kit, because it should be issue for the manufacturer to shiplap all mitered joints to code for an easy assembly.

I opted to tackle the job of replacing my entire duct system myself when the estimate to have pro's do it was in excess of $3000 - and moving up to $4800 after April 1st because of the heat in FL. The junction box that served the far side of my house had obviously been used as a seat by someone and was completely crushed and had a gash in the top, so I had to construct a new junction box, and this was just what I needed. The instructions on the packaging were clear and easy, and the materials were of good quality, and cut easily with a box cutter and a duct knife. To make a complete box with a top and a bottom, you will need 2 kits, as the kit only comes with one panel for top or bottom.

This duct board plenum kit worked perfectly for my application. I purchased 3, because I had to get the extra sides to build 2 complete boxes, which is my biggest complaint. the only way I knew it was not a complete box was because another reviewer mentioned the same thing. I used 1 box as a supply sub-plenum, 25 ft away from the main furnace supply plenum. 14" flex run in, (3) - 8" flexes out, split to (6) 6" register connections. I used the other box as a return sub-plenum, 35 ft away from the main furnace return plenum. 14" flex run to the box, branching to (4) 8" flexes to return runs in stud cavities. The boxes were easy to assemble once I figured out how to do it, although it takes a while to build them. Comes in 3 "pieces", which make up 5 sides. 2 of the pieces are ready to fold into a half square, with 2 corner seems to tape completing the square. The 3rd piece is an end, with all 4 edges to tape. Fabricating a 6th side from the 3rd plenum kit was easy, just took a side with 3 "beveled" edges, and added a 4th bevel edge using a utility knife. Cutting material is very easy and clean. Used a utility knife with a sharp blade, cuts through like butter. In order to cut completely through the thick material, I used a sharp lock blade knife to finish the cuts. Minimal mess, easy to cut clean holes, no "sawing" required. I would choose to work with this material over sheet metal any day. One more thing. Material is itchy hard fiberglass. Use gloves, try not to get it on your skin.

There was no way you could make a plenum out of them by just folding and taping. I ordered 4 and everything about them were all cut wrong. Got me some duct board, got out the ol cutters and did it myself. Over 50 years in the business I know a little about it.

The pieces did not match the instructions. I was able to cut them to allow them to fit together properly. Also, this product is way overpriced for what it is.
