Punch-Free Window Exhaust Fan Vertical Frame, Slim Retractable Design Ultra-Quiet Brushless Motor Ventilation for Smoky Spaces Bedroom Kitchen Living Room(White,57-59in)

When you live in a rented room, you cannot drill holes in the walls or mess up the window frames, but you still need a way to clear out stale, stuffy air. This vertical exhaust fan is the perfect loophole. Open your window, set the aluminum frame into the track, and let the spring tension hold it tight. No screws, no damage, no angry landlord. Turn the dial switch to activate the five extraction fans. Whether it is lingering cooking smells, dampness, or just a heavy room atmosphere, you can feel the bad air being actively pushed outside. The low-profile build means you can slide the window shut right against the fan body. When it is time to move out, just press the spring and take it with you in two seconds.Key Specifications:Noise Level: 16 dB (Ultra-Quiet)Speed: 2800 RPM (Stepless Adjustable)Motor: High-Efficiency 12V BrushlessAirflow: 98 CFMPower: 35 Watts (Energy-saving AC)Thickness: 1.57 inches (Slim-fit)Before You Buy:To ensure a seamless fit, please measure the inner vertical height of your window frame (from the top track to the bottom track).

• Vertical Clearance Match: Requires sliding window frames measuring 29.5 to 31.5 inches; mandates exact measurement of the inner track channel; locks into the frame using a 1.97 inches tension spring
• Heavy-Duty Air Extraction: Moves airborne particles and humidity outside the enclosed room; integrates an aluminum alloy chassis to prevent physical warping; operates strictly as an outward-facing ventilation unit
• Bracket-Free Setup: Implements a spring-loaded design for immediate vertical placement; fastens securely inside the track without hardware modifications; leaves the existing window casing entirely unaltered
• Compact Chassis Design: Rests flush against the window track for a low-profile footprint; encases five rotary fan blades behind a stainless steel grate; permits the main window panel to close adjacent to the unit
• Manual Rotary Control: Regulates fan velocity smoothly from minimum to maximum output; changes the rate of air displacement based on physical settings; provides controlled exhaust for localized indoor environments
