Universal Portable AC Window Vent Plate Adapter

Stop Draughts and Warm Air Sneaking Back Through Your Window

A portable air conditioner only works as well as its exhaust setup, and a gap left around an open window can undo a lot of that cooling effort. The Stornfield window ventilation panel adapter was designed to solve this exact issue, turning a standard sliding window into a secure, sealed connection point for your unit's exhaust hose.

The set includes two interlocking panels, a circular hose opening, and mounting hardware, so instead of propping a window open with towels or cardboard, you get a stable, draft-resistant fit built for the job.

Because the sliding panel adjusts to fit varying window widths, installation tends to be a one-time job at the start of the season rather than something you have to redo every time you move the unit. Once fitted, it stays in place, so the same window can go from open to sealed and back again in moments.
