Unisex universal size wide flat window sealing panel for portable air conditioner with universal round exhaust collar and quick-release elastic straps Kalsten

Product Overview

Designed for homeowners and renters who need a clean, energy-efficient ventilation solution, this Kalsten universal flat window ventilation sealing module fits most portable air conditioners as well as sliding or casement windows. The flat black plate creates a tight seal around the exhaust hose to keep out drafts, dust, and insects, while providing a discreet, professional look for temporary or seasonal installations.

Key Features

• Universal Compatibility: Works with most single-hose portable air conditioners and standard round exhaust ducts.
• Double-size Exhaust Collar: Built-in universal round collar accepts common hose diameters for a seamless connection.
• Generous Coverage: The plate measures 59 inches x 21 inches (150 cm x 53 cm) to cover wide window openings and reduce the backflow of warm air.
• Quick-Fit Elastic Straps: Includes adjustable elastic straps for quick, secure installation and added stability.
• Durable Weather-Resistant Material: Sturdy, flexible plate resists cracking and blocks light to enhance insulation and privacy.
• Portable and Reusable: Can be rolled or folded for compact storage between seasons and reinstalled in minutes without tools.
