- Adjustable length: Our air conditioner seal is available in two sizes, approximately 300 cm and approximately 400 cm. You can adjust the length to fit your needs. It fits all types of sliding panels for horizontal or vertical configurations and is compatible with all portable air conditioners or air dryers. - Prevents air loss: Made from special TU fabric for insulation and treated with a new heat-insulating process, this seal effectively blocks the loss of cold air and reflects sunlight and heat outward. This helps cool the room quickly, save energy, and reduce costs. - Full seal: The seal provides a tight and gap-free installation thanks to the material and extended high-strength adhesive. By preventing cold air from escaping and keeping flies out, it offers excellent protection. - Enhanced details: The seal features precise cut and milling areas for adjustment without distortion. In addition, the texture treatment near the outlet prevents the tape from detaching after the exhaust hose is inserted, avoiding gaps. - Use scenarios: - Cooling a bedroom in hot weather with a portable air conditioner by sealing around a sliding window. - Enhancing the efficiency of portable ACs or dehumidifiers in apartments or dorm rooms with sliding windows (horizontal or vertical). - Maintaining effective cooling in RVs or travel trailers with sliding windows during trips.
