Size: 5.9 Inch Window


Features

  • Seamless card slot design: Compared to the first generation ventilation panels that required tape sealing, we optimized the panel's chute structure to ensure seamless side connections between all panels after assembly. Designed specifically for specific portable air conditioners with 5.9-inch diameter hoses, this 2024 latest upgrade innovative design completely eliminates the edge gaps often present with traditional sliding door and window kits.
  • Card slot design makes sliding easier: What is different from other designs is that our window vent kit side slots are slid into an inverted triangle structure. During our many tests, we found that this structural design increases the lower contact surface, making it easier to match the interface and assemble the board than the rectangular design; the inverted triangular structural design makes the spatial structure more stable and more Beautiful.
  • Using Better Raw Materials: our air conditioner window kits are made of new reinforced PVC material, which has better heat resistance, wear resistance, aging resistance and durability, ensuring a longer service life. Can keep you cool through every summer, you don't have to worry about exposing it to the sun, it won't crack and peel.
  • Package Includes: window vent kit includes 4 plates, 1 coupler, 1 bird guard, 4 screw accessories & 2 Window Seal. Suitable for LG, whether, Haier, Hisense and other air-conditioning accessories.
  • Adjustable Track Design: SunDiao Portable AC window vent kit has a User-friendly rail design, easy to slide the seal plates, and fast lock, very sturdy. Suitable for all portable air conditioners with 5.9"/15cm diameter hoses. Adjustable length range: 17 inches-61 inches.
  • Good sealing: Even though we have upgraded the ac vent kit sealing design, we are still equipped with sealing strips that can bridge the gap between the fixed plate and the adjusting plate to achieve a good sealing effect and keep your room cool at all times.
  • Free assembly & applicable windows: our window kit is suitable for most vertical and horizontal sliding windows. You can use a 2-plates combination, 3-plates combination, or 4-plates combination according to the size of the window. Be satisfied with the needs of different window heights.

  • Does the job so far!
Intend the find the easier something goes together, the more poorly made an item is. This wasn’t easy to put together, but it is simple in its design. Everything fits together very well, but you need to be careful when assembling. This ensures there’s no gaps anywhere, which I really appreciated. I like the sliding metal plates to screw down the pieces. It’s much more heavy duty than the window adapter that came with my unit. The additional 3m weather stripping that came with was super easy apply and adheres quickly. I had some trouble getting the exhaust hose into the port. I suppose I should have put it in the insert port before putting the port into the panel. Overall, it’s doing what I need it to do, which is let me kick the hot exhaust outside rather than into my garage through a dog door, which is what I was doing before haha. It also allows me to have my portable unit in my living room where it’s most effective. If anything changes, I’ll update my feedback. ... show more

  • Way less gaps than the original
The original Honeywell portable AC vent was pretty uneven where I had to use painters tape to try to close the gaps. The hole where the hose is attached to was also very narrow that in a window where you had to slide part of it into the window slits in order for the whole window kit to stay up and to reduce any gaps of air coming from outside, there would be no room for the hose to attach to the board. This one gives you plenty of room to slide the window kit board through both sides of the window slits. The weather strips that came with the kit was useful as well. Some of the adhesive wasn’t very sticky but if you put the strips on right and they stay up, I actually felt less air coming in and out. This means even if I didn’t have my portable AC installed, my room was less hot and less cold. ... show more

  • Better quality than came with unit
Size: 5.9 Inch Window
I like the sturdiness of the plastic and the nice tightener that is a higher quality than what came with the DeLonghi unit. It was fast to put together for my bedroom window and I put some foam around it to seal it up good as well as wood dowels to keep the window solidly down on the top of the vent unit. This is a much better quality and huge upgrade to what came with my unit. I am very happy with it and would buy it again if need be, however I feel this will last several years. Thank you for your great review Fish! ... show more

  • Works great but installation instructions are lacking
Size: 5.9 Inch Window
It works great, but the installation instructions are lacking. I went to the product on Amazon to find the installation video listed on the instruction pamphlet, but it did not state how to install the seals, so I just guessed. Otherwise, the product is sturdy.

  • My ac parts
This piece works well, you might need to make a few adjustments so it fits in your window.

  • Quite flimsy and not standard 5.1
Size: 5.1 Inch Door
The material (plastic) is thinner than i expected and quite flimsy (moves a lot) when extended to fit tall slider. Worse, the output coupler is not standard 5.1. It’s taller and more narrow. I had to rig it to work with the window setup my system came with. Thank god for duct tape.
