Exhaust Shutters and Weather Hoods

Gravity exhaust shutters are used to keep air flow from blowing back into your exhaust fan when the unit is turned off. This helps with unwanted outside air entering your space. Another use is a passive solution to allow air out of your space when using a supply fan. They also keep water out when closed, and are available with optional bird and bug screens. They can be installed directly on a building wall, and are also able to be directly mounted onto some fan housings.

Motorized exhaust shutters are used to keep air flow from blowing back into your exhaust fan when the unit is turned off. They utilize a small electric motor to open and close the shutter. This motor also keep the shutters closed against any wind that can force gravity operated units open. They keep water and wind out when closed, and are available with optional bird and bug screens. They can also be installed directly on a building wall, and are also able to be directly mounted onto some fan housings.

Gravity intake shutters are typically used on the opposite wall that an exhaust fan is placed, to allow for fresh air to enter your space while the exhaust fan is running. This prevents a negative pressure situation that can prematurely burn out your fan motor. These gravity operated intake shutters require you to manually open them via a pull chain prior to turning your exhaust system on. 

Breathe easy with motorized intake louvers. These aluminum shutters automatically open and close, controlling airflow with precision. Designed for warehouses, greenhouses, and commercial buildings, they keep fresh air flowing while blocking wind and debris. Unlike manual dampers, these louvers work with your exhaust system, improving efficiency and saving energy. Built tough, they stand up to the elements, keeping your space comfortable year-round. Whether you need better ventilation or protection from harsh weather, these motorized louvers get the job done—no hassle, no wasted energy. Upgrade today and experience the difference.

Exterior wall rain hoods are a type of protective cover that is installed on the exterior wall of a building to prevent rain and other forms of precipitation from entering through the ventilation system.  These hoods are typically used in conjunction with exhaust or intake vents, and are designed to prevent water from entering the vent and potentially causing damage or creating a hazard.  These rain hoods are available in plastic or metal and are available with optional bird screens.

Round backdraft dampers are devices used to prevent the backflow of air in ventilation systems. They are typically installed in the ductwork of commercial and industrial buildings and are designed to allow airflow in one direction while preventing airflow in the opposite direction. Round backdraft dampers work by using a spring-loaded or gravity-operated door that closes when air flow in the opposite direction exceeds a certain level. When the airflow is in the correct direction, the door opens, allowing air to flow through the ductwork.

Fire rated dampers are designed to prevent the spread of fire and smoke through ductwork in the event of a fire. They are an important component of fire protection systems in buildings, and are typically required by building codes and standards.  Fire rated dampers are installed within ductwork and are designed to automatically close when a spring loaded trigger is activated from elevated temperature levels.
