Versatile: this 300 cm long window seal for mobile air conditioners can be installed on windows with a circumference of up to 300 cm. It is suitable for roof windows, tilt windows, casement windows as well as left and right side windows, but not for sliding windows. This roof window air conditioning seal is suitable for all mobile air conditioners, tumble dryers, dehumidifiers and more and allows for more efficient operation of these devices by dissipating warm air even when the window is open.
Tips: 1. Clean the window frame before applying the adhesive. 2. The curved side of the air conditioner window seal is attached to the outer window frame, the straight side on the inside. 3. It is recommended to start mounting in the middle of the window frame. Please measure the window size and confirm the window type before purchasing. If your window seal has unnecessary material, you can overlap it at both ends for a cleaner look.
Portable and reusable: our portable air conditioner window seal is not a disposable product. The air conditioning window can be removed and cleaned if dirty. After summer, wash the seal at 40 C and store properly to reuse next summer. This saves money! Thanks to two double-sided zippers, you can adjust the opening size to the hose diameter and use it for mobile air conditioners with one or two hoses.
High-quality material: Our air conditioning window seal is made of durable, high-density PU-coated fabric, which provides excellent thermal insulation and reflects sunlight, effectively shortening the running time of the air conditioner. They are also soft and seal well. They are waterproof, windproof, rainproof and UV resistant and are therefore also suitable for use on rainy days. They keep your room cool on hot summer days and create a quiet and comfortable space for you!
Excellent sealing: the hinge of the window seal for mobile air conditioners has an extremely robust two-way zip that provides a secure two-way closure and an absolutely seamless seal. The high-quality, residue-free closure ensures a secure fit and comes with a strong hook tape so that the strap does not peel off and avoid damage. This provides a tight, even seal around the window, optimises cooling performance and keeps external influences away.
Efficient cooling, energy saving: air conditioning window seal dissipates warm air through the air conditioning channel from the air-conditioned room and prevents backflow. This allows for more efficient cooling of your room, reduces energy consumption, saves electricity costs and CO2 emissions while protecting the environment. Window seal for mobile air conditioners effectively repel insects, mosquitoes and rain and create a "sealed environment" that quickly lowers the indoor temperature and keeps your room cooler for longer.
Easy installation: no drilling or other tools required. The Wbbrbbr air conditioning window seal comes with everything you need. Simply attach the included adhesive tape to the window frame, attach the air conditioning window seal to the window and frame, pull on the window seal and remove the AC hose from the window. Then close the hose tightly with the zip, and you can open or close the window at any time.
