Adjustable Window Exhaust Seal Plate Kit for Portable Air Conditioners

Optimize the performance of portable air conditioners and stop drafts with the adjustable window exhaust seal plate kit from Stornfield. Specifically designed for hung, awning, and sliding windows, this universal ventilation solution creates an airtight, weather-resistant barrier for exhaust hoses and prevents warm air, dust, and insects from entering your room. The SEO-friendly design and clear measurement instructions make this kit ideal for DIY installation and energy-efficient cooling.

Main Features

• Universal fit for sliding windows: designed for hung, awning, and sliding windows; not suitable for horizontally or vertically sliding windows.
• Adjustable size: clear measurement instructions with the formula + b + c for a reliable fit – the total perimeter should not exceed the recommended limit for full sealing performance.
• Sturdy, weather-resistant construction: durable fabric with reinforced seams and a flexible frame keeps the plate stable and reduces air leaks.
• Airtight sealing system: integrated seals and adjustable edges form a tight seal around window frames and exhaust hoses to reduce energy loss and noise.
• Tool-free installation: quick mounting with Velcro strips, adhesive seals, and simple accessories for most window frames; quick disassembly for storage when not in use.
• Compact and foldable: lightweight, foldable design stores flat and packs easily for seasonal use or travel.

Compatibility & Dimensions

Measure the three edges marked a, b, and c in the diagram to confirm fit. The kit is optimized for window openings where the sum of a + b + c is within the maximum perimeter of the product. This measurement method ensures that the foldable plates close cleanly around sliding windows and provide a secure seal for exhaust hoses.

Installation Overview

• Step 1: Measure your window opening (see diagram a, b, c) and confirm that the total perimeter matches the kit specifications.
• Step 2: Attach the adhesive sealing strips to the window frame to create an initial airtight barrier.
• Step 3: Position the foldable plate over the window and secure it with the provided mounting materials or Velcro fasteners.
• Step 4: Insert the exhaust hose of the portable air conditioner through the opening of the plate and tighten the adjustable collar or seal to prevent leaks.
• Step 5: Test for drafts and make small adjustments for a snug fit; remove and store when the cooling period ends.
