• ◆ MEASURE YOUR WINDOW FIRST – This vertical window fan is designed specifically for sliding windows, requiring an inner frame height of 31.5"to 33.5". Please measure the vertical window frame space (not the glass height) for a perfect fit. Not compatible with windows outside this height range.
• ◆ TOOL‑FREE INSTALLATION IN 30 SECONDS – No screws, drilling, or permanent modification. Simply extend the spring‑loaded frame, place it between the window tracks, and tighten. Removes easily without damaging your window – ideal for quick, temporary exhaust needs.
• ◆ ULTRA‑SLIM DESIGN THAT DOESN’T BLOCK YOUR WINDOW – The vertical profile sits flush against the frame, allowing normal window operation. Multiple high‑performance fans behind a stainless steel mesh deliver safe, quiet, and energy‑efficient airflow – perfect for kitchens, bathrooms, bedrooms, and smoky or pet spaces.
• ◆ STEPLESS SPEED CONTROL FOR CUSTOM AIRFLOW – Turn the dial to adjust from a gentle breeze to powerful exhaust (0–2800 RPM) with infinite variability. Whether you need light ventilation or rapid smoke/odor removal, this fan adapts instantly to your comfort needs.
• ◆ DURABLE, WEATHERPROOF & EASY TO CLEAN – Built with a rust‑resistant aluminum alloy frame and a double‑layer stainless steel grille that blocks debris and withstands rain. The smooth surface wipes clean in seconds, ensuring long‑lasting, maintenance‑free performance in attics, garages, basements, or any humid environment.
