EFFICIENT COOLING, ENERGY SAVING - The window seal for mobile air conditioners helps to drain warm air from the air-conditioned room through the hose and prevents it from flowing back. Cool your room more efficiently while reducing energy consumption, reducing your electricity bill and reducing carbon dioxide emissions to protect the environment. Wide Scope of Application Our window seal was designed for mobile air conditioners and air vent dryers, to evacuate hot air and allow the device to work more efficiently, even when the window is open. Suitable for most commonly used tilting windows and casement windows with a maximum circumference of 400 cm, but not for sliding windows. EFFORTLESS INSTALLATION No complicated steps like drilling holes or using additional tools are required. Follow the detailed instructions in German to complete the installation in minutes. It is easy and convenient for you to apply the adhesive fastener on the frame, stick the window seal on the frame, install the exhaust pipe and close the zippers. PERFECT CHOICE FOR SEALING - The universal window seal is made of strong and thick 210T polyester with PU coating, for waterproof protection. The window seal not only regulates the air exchange inside and outside the air-conditioned room, but also protects the cool indoor climate from dust and dirt, strong winds, sudden rains and insects. Practical and economical: window seals for mobile air conditioners are not intended for single use. Wash the seal at 40 ° C and store it for next summer. - -, Manufacturer: KGOGO
