• Snap-Fan Exhaust Shutter: The Essential Accessory for Your

The Essential Accessory for your Ventilation System

Complete your high-efficiency ventilation setup with the durable and reliable Snap-Fan Exhaust Shutter by Fogco. This passive shutter is the perfect companion to your Snap-Fan, designed to protect your investment and improve the overall efficiency of your climate control system providing a critical barrier against the elements.

Automated, Passive Weather Protection

The beauty of the Snap-Fan System lies in its simplicity and effectiveness. This is a "passive" shutter, meaning it requires no electricity or manual operation. The precision-balanced aluminum louvers are designed to be blown open by the airflow from your exhaust fan when it's running. When the fan powers down, gravity gently closes the louvers, creating a secure seal over the fan opening.

This automated action provides several key benefits:

• Weather Resistance: Prevents rain, snow, and wind from entering your building through the fan opening when it is not in use.
• Pest and Debris Barrier: Keeps out insects, birds, rodents, and blowing leaves, protecting your fan and the interior of your structure.
• Prevents Backdrafts: Stops unwanted air from flowing back into your space, which is crucial for maintaining stable indoor temperatures and preventing energy loss.
• Retains Heat: In cooler months or overnight in a greenhouse, the closed shutter helps keep valuable warm air inside, reducing heating costs and protecting sensitive plants.

Durable, Corrosion-Resistant Construction

The Snap-Fan Exhaust Shutter is constructed entirely from high-quality, corrosion-resistant aluminum. This lightweight yet strong material ensures that your shutter will not rust or degrade, even in humid environments like greenhouses or in outdoor applications exposed to the elements.

Essential for a Wide Range of Applications

• Greenhouses and High Tunnels: Protect your controlled environment agriculture (CEA) operation by preventing heat loss at night and keeping pests out.
• Attics and Crawlspaces: Seal your solar attic fan opening to prevent cold winter air from being drawn into the attic, which can negate the benefits of your insulation.
• Sheds, Garages, and Workshops: Keep your workspace protected from the elements and secure from pests when your exhaust fan is off.
• Barns and Chicken Coops: Provide a necessary barrier to keep animal enclosures warmer and free from drafts during colder periods.
• Off-Grid Buildings: Enhance the energy efficiency and resilience of tiny homes, cabins, and other remote structures by sealing a key point of potential energy loss.

Installation and Sizing:

Installation is straightforward for any DIYer or professional. The shutter is designed to be mounted on the exterior of the wall where the fan is exhausting air. For best results, the rough opening should be slightly larger than the shutter frame to allow for easy fitting.
