Universal window sealing set for portable AC HECHT – HECHT 003912

For HECHT3912 / HECHT 3913

Universal window sealing set for mobile air conditioning HECHT 3912 / HECHT 3913. The sealing set is made of durable fabric. You can easily stick the sealing set on the window frame and window sash. When the window is ajar, the fabric closes the gap and prevents warm air from entering the room from outside. The sealed one is equipped with a zipper, which allows the window to be fully opened after opening.

If you close the zip seal, all you have to do is pass the hose through the hole, which conducts the waste heat from the air conditioner. At the same time, the seal prevents difficult insects from flying through the window into the room. At the same time it saves your wallet by keeping the hot air outside and the air conditioner doesn’t have to cool down unnecessarily long and switches on less often.
