Fully Adjustable Airflow!

"This fit snugly in my sliding window and was much easier to install than a permanent exhaust fan. The variable controller lets me keep it quiet for everyday airflow or turn it up when cooking odors build up." - Beatriz Santillan

Why Get Our Detachable Window Exhaust Fan for Sliding Windows?

✅ Targeted Air Exchange: Stale air, smoke, pet odors, and trapped heat can make enclosed rooms uncomfortable. Five high-performance fans provide focused ventilation and can be configured to bring fresh air inside or exhaust hot, unwanted air.

✅ Precise Sliding-Window Fit: Designed for sliding windows with up to 49-inch vertical inner-frame height and a 1.97-inch extendable spring mechanism. Measure the open inner-frame space—not the glass height—before ordering to ensure a snug, gap-free fit.

✅ Tool-Free & Adjustable: Extend the spring-loaded aluminum-alloy frame, position it inside the window opening, and release it to hold securely—no drilling, tools, or permanent marks required. A stepless speed controller provides smooth airflow adjustment, while stainless-steel mesh protects the five fans and supports everyday window use when correctly installed.
