FAQs for Weather Hoods, Guards and Shutters
Get quick answers to common questions about weather hoods, guards and shutters, and how these accessories help protect ventilation equipment while supporting effective airflow.
Weather hoods are designed to help protect ventilation openings from rain and other outdoor elements while still allowing air to move freely. Their shape helps shield the opening and reduce the potential for water intrusion, although no ventilation opening is 100% weatherproof under every condition.
A guard provides a protective barrier around a fan or ventilation opening, helping to prevent accidental contact with moving components and keep larger debris out. A shutter uses movable blades that open when air is flowing and close when the fan is off, helping to protect the opening and limit unwanted airflow.
A motorized shutter is a good option when you need greater control over airflow and when the shutter is engaged. Rather than relying on airflow to move the blades, a motor opens and closes the shutter as needed.
Not every wall exhaust fan requires a weather hood, but one may be beneficial when the fan opening is exposed to rain and other elements. Needs will vary based on factors such as the fan, building design, installation location and project requirements.
They can help. By protecting fans and ventilation openings from debris, accidental contact and exposure to damaging elements, guards and hoods can reduce wear on equipment and support reliable, long-term performance.
A weather hood should be sized to accommodate the airflow requirements of the fan or ventilation opening without creating excessive restriction. Fan CFM, opening size and the hood’s available free area should all be factored in, making it important to properly match the hood to a structure’s unique ventilation equipment and application.
Yes. When a fan shuts off, properly fitting shutters close over the opening to help keep reverse airflow, or backdraft, from entering the building. They can also help keep outside air and debris out when the ventilation system isn’t in use.
