It effectively expels hot air generated by the air conditioner out of the window whilst trapping cool air inside, keeping your room cool for longer - Improved Cooling Performance and Energy Savings: The AC window seal kits are made from durable nylon, effectively preventing hot air from entering and keeping out insects and rain, creating an ‘airtight environment’. This allows the room to cool down rapidly, enhancing the air conditioning’s cooling efficiency, helping to reduce energy consumption and carbon dioxide emissions, saving on electricity bills and putting money in your pocket - Suitable For a Wide Range Of Portable Air Conditioners: This portable AC window vent kit features a flexible dual-zipper design, making it suitable for both single-hose and dual-hose units, and allowing the hose to be secured at any height. It effectively resolves the common issue of aligning the air conditioner with the window. The window seal is compatible with portable air conditioners, tumble dryers, dehumidifiers and other household appliances, offering versatile use across a variety of scenarios - Suitable For a Wide Range Of Windows: We offer five sizes of portable AC window vent kits to choose from, including 300 cm, 400 cm, 500 cm, 560 cm and 600 cm. These are suitable for skylights, sunshade windows, casement windows or left/right-opening outward-opening windows. They are not suitable for sliding windows, vertical sliding windows or pivot windows. Please measure the length of all four sides of your window before purchasing, then select the appropriate size to ensure you buy the correct product, install it correctly and achieve a better seal - Easy to Install: No drilling required. You won’t need to buy a window installation kit, hose adapters or any extra tools—our portable AC window vent kit includes all the necessary accessories (excluding the exhaust hose), along with a comprehensive installation guide! Simply secure the portable AC window vent kit to the inside of the window frame and the window itself using tape, feed the air conditioning hose out of the window, zip it up, and secure it with cable ties. You can open and close the window at any time without removing the window seal. Of course, you can also remove the AC window seal kit when not in use, store it away and reuse it later ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Q881Z75 | | Additional Features | portable ac window vent kit | | Air Conditioner Application | Residential | | Best Sellers Rank | #349,608 in Home & Kitchen ( See Top 100 in Home & Kitchen ) #503 in Accessories (Home & Kitchen) | | Brand | Gruntbear | | Brand Name | Gruntbear | | Color | White | | Compressor Type | reciprocating | | Control Method | App | | Controller Type | Manual | | Customer Reviews | 3.9 out of 5 stars 490 Reviews | | Efficiency | mejora la eficiencia | | Form Factor | no | | Included Components | Adhesive hook tape, zip closure | | Installation Type | Window | | Inverter Type | No Inverter | | Manufacturer | Gruntbear | | Model Name | portable ac window vent kit | | Model Number | portable ac window vent kit | | Number Of Circuits | 1 | | Number of Power Levels | 2 | | Operating Mode | no | | Power Source | NO | | Room Type | Bathroom | | Special Feature | portable ac window vent kit | | Start Year | 2023 | | Start year | 2023 | | Unit Count | 1 Count | | Voltage | 110 | | Warranty Type | NO | | Window Opening Maximum Height | 49.71 inches | | Window Opening Maximum Width | 78.5 inches | | Window Opening Minimum Height | 82.6 inches | | Window Opening Minimum Width | 78.5 centimeters | ## Product Details - **Brand:** Gruntbear - **Color:** White - **Control Method:** App - **Form Factor:** no - **Model Name:** portable ac window vent kit - **Power Source:** NO - **Special Feature:** portable ac window vent kit - **Start year:** 2023 - **Voltage:** 110 - **Warranty Type:** NO ## Images ![Portable Air Conditioner Window Seal Kit for Casement 400CM/157” - Image 1](https://m.media-amazon.com/images/I/615zaomednL.jpg) ![Portable Air Conditioner Window Seal Kit for Casement 400CM/157” - Image 2](https://m.media-amazon.com/images/I/618t1bZa1pL.jpg) ![Portable Air Conditioner Window Seal Kit for Casement 400CM/157” - Image 3](https://m.media-amazon.com/images/I/61X6EcC4+cL.jpg) ![Portable Air Conditioner Window Seal Kit for Casement 400CM/157” - Image 4](https://m.media-amazon.com/images/I/71-Fq+9ThBL.jpg) ![Portable Air Conditioner Window Seal Kit for Casement 400CM/157” - Image 5](https://m.media-amazon.com/images/I/61iKjd0SfeL.jpg) ## Available Options This product comes in different **Size** options. ## Frequently Bought Together - Gruntbear Portable Air Conditioner Window Seal Kit, 400CM (157'') AC Casement , Hot Air Stop Air Exchange Guards with Zip and Adhesive Fastener Works with Tumble Dryer, Keep House Cool - 3-in-1 Portable Air Conditioner with Built-in Dehumidifier Function,Fan Mode, Remote Control, Complete Window Mount Exhaust Kit - Portable Air Conditioner Hose - AC Hose with 5.9" Diameter, Anti-Clockwise Thread, Length up to 80" - Exhaust Hose for Portable Air Conditioner Vent Compatible with Delonghi & LG Air Conditioner Parts --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/416206701-portable-air-conditioner-window-seal-kit-for-casement-400cm-157](https://www.desertcart.tn/products/416206701-portable-air-conditioner-window-seal-kit-for-casement-400cm-157) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-11-11*
