Enhance your vehicle’s ventilation with the Slim-Matic Wind-Powered Rotating Air Vent Fan featuring a Round Shutter for precise airflow control. Designed for commercial vans, RVs, trailers, and campers, this ultra-slim vent—standing just 2.2 inches tall—is ideal for vehicles equipped with roof racks or additional installations.

Powered entirely by wind, the Slim-Matic efficiently extracts stale air, moisture, and heat without requiring electricity. At highway speeds, it moves up to 76.5 cubic feet of air per minute (CFM), keeping your vehicle interior fresh and comfortable. Even while parked, its aerodynamic design allows for passive air exchange, ensuring consistent airflow when your vehicle is unattended.

The Round Shutter design offers a customizable ventilation solution, making it a versatile fit for various roof styles, including those found on Ford Transit, Mercedes-Benz Sprinter, and other commercial vans. Built to withstand harsh weather conditions, this durable vent helps prevent moisture buildup, protecting both your cargo and vehicle interior. Note: The round shutter is not recommended for RAM ProMaster vans due to the narrow ribbing in the roof (use the Rectangle Shutter option instead). 

Key Features:
✅ Ultra-Slim Profile – Just 2.2″ in height, allowing installation under most ladder racks
✅ High-Efficiency Ventilation – Moves 76 CFM at 65 MPH, refreshing air in a high-roof van in just 7 minutes
