VEVOR Shutter Exhaust Fan, 305 mm with Temperature Humidity Controller, EC-motor, 904 CFM, Variable Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds

Wall Mount Attic Fan with 904 CFM Airflow for Powerful Ventilation 

When the VEVOR wall mount attic fan is running at 1,650 RPM, it moves a lot of air at once—904 CFM (1,500 m³/h). This makes it suitable for a variety of indoor and semi-outdoor ventilation applications. The 904 CFM airflow helps remove heat, humidity, smoke, and stale air from enclosed spaces. This makes it a useful choice for agricultural buildings, attics, garages, workshops, and other spaces that require ample airflow.

The 305 mm (12-inch) fan diameter moves a good amount of air without requiring oversized fitting holes. Louvered shutters that open automatically when the fan is running and close automatically when it stops also keep out cold drafts, bugs, and other debris when the fan is not running. Once installed, this passive sealing device requires no separate actuator or manual work, making day-to-day operation simple. 

Energy-Efficient 40W EC Motor for High Performance at Low Running Cost 

This wall mount attic fan has an EC (electronically commutated) motor that uses only 40W yet moves 904 CFM of air. This is a much better power-to-performance ratio than regular AC motor fans with the same output. EC motors are naturally more efficient because they turn electrical energy into mechanical work with reduced heat loss. This means they use less power when running all the time. This makes the unit especially cost-effective in places where the fan runs for long periods each day.

The EC motor is designed for efficient and reliable operation while reducing energy consumption. Controlling the fan's speed lets it exactly match the current ventilation need instead of running at full capacity all the time. This further lowers energy use and noise levels when only partially loaded. 

Full Metal Construction with Aluminum Alloy and Powder-Coated Steel Housing 

This wall mount attic fan is constructed entirely of metal. The louvers, mesh cover, fan body, and all the parts that connect them are all made of aluminum alloy and powder-coated steel. The aluminum alloy and powder-coated steel construction provides added durability for demanding environments.

The IP44-rated housing provides protection against solid objects and splashing water, making it suitable for many indoor and sheltered installations. When installed outdoors for years, the powder-coated finish keeps the fan's appearance and integrity intact, as it does not rust or wear out easily over time. Overall, the build quality of the unit suggests that it was made for heavy-duty work settings rather than light home use.

Temperature and Humidity Controller for Fully Automated Operation 

The built-in temperature and humidity controller lets the fan turn on and off automatically based on the current temperature and humidity, so you do not have to monitor it or turn it on and off all day. The user sets the desired temperature and humidity levels, and the controller responds by turning on the fan when the levels exceed the set point and turning it off when they return to the target range. This automation is very helpful in places like greenhouses, chicken coops, and storage areas where maintaining stable conditions is important.

When the fan is turned off in winter or left off for long periods, the louvered shutters close automatically. This helps keep the inside temperature stable and prevents unwanted air from moving through the hole. The unit comes with a remote control that lets you adjust settings without touching the fan itself. This is helpful if the installation point is high up or otherwise hard to reach while the unit is running.

Detachable Steel Mesh Screen for Protection Against Debris and Insects 

When the fan is running, the upgraded steel mesh screen keeps insects, debris, and airborne particles from entering the installation space through the fan opening. The steel mesh construction makes it much more durable and less likely to bend than the plastic mesh on rival units. It keeps filtering well even after being taken apart and put back together many times for cleaning. Protective gloves are in the box so that you can safely attach and remove the screen.

The screen is not pre-assembled on purpose, so users can decide for themselves how to install it based on their needs and surroundings. The screen adds an important layer of protection in places with many bugs or dust in the air, like farms, woodworking shops, or garages near the outdoors or open areas. 

Wall Mount Attic Fan Designed for Garages, Greenhouses, Sheds, and More 

This wall mount attic fan makes 67 decibels of noise, which is low enough to be used in places other than factories and can also be used in businesses, hospitals, and theaters. The low noise level and smooth, variable-speed operation of the EC motor ensure the fan does not bother people working or living in the area, even when it runs all day. By stopping the motor from overheating during long periods of continuous use, the overload safety system keeps fires from starting.

Installation requires only one 380x380mm wall opening, and it comes with a 1.8m power cord that connects to a standard 220V/50Hz power source. The fan comes in four parts that are easy to put together, and the package includes all the hardware you need to hang it on the wall. Garages, workshops, attics, chicken coops, sheds, gardens, offices, hospitals, and theaters are all suitable locations. It can effectively meet the ventilation needs of both homes and light businesses.
