VEVOR Shutter Exhaust Fan, 406 mm with Temperature Humidity Controller, EC-motor, 1747 CFM, Variable Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds
- New Version: What are the differences between the new version and the old one? Firstly, in terms of material, the new model uses full metal material. The louvers, mesh cover, fan body, and even the connecting parts are all made of metal, ensuring a more sturdy product and reducing the possibility of deformation during transportation. Additionally, the new version also features an upgraded motor, providing a longer lifespan.
- High Performance: The HG POWER exhaust fan is an upgraded iteration of existing similar products, boasting a high airflow of 1747 CFM（2900 m³/h） , a high speed of 1600 RPM , and a low power consumption of 70 Watts . This combination renders the fan both potent and energy-efficient, capable of circulating significant volumes of air.
- Steel Mesh Screen: This wall vent fan includes an upgraded, detachable steel mesh screen designed to safeguard your home against external debris. For installation, kindly use the provided gloves to prevent injury. We chose not to pre-assemble the screen, giving you the option to decide whether to use it or not.
- Automatic Shutdown: The high-quality materials used in the housing and grille ensure that the fan maintains excellent performance even in harsh weather conditions like rain and snow. The louvered fan automatically shuts down during the winter when not in use to help maintain indoor temperature.
- Wide Application: Operating at a low noise level, this wall exhaust fan can be effortlessly installed in garages, workshops, chicken coops, sheds, attics, greenhouses, offices, hospitals, and theaters. You only need to allow for the proper installation thickness to complete the setup.

About this item
Variable Speed Shutter Exhaust Fan with Full Metal Construction for Long-Lasting Durability
VEVOR makes this variable speed shutter exhaust fan out of metal all the way through: the louvers, the mesh cover, the fan body, and all the parts that connect them. Plastic-bodied options bend and warp during shipping and long-term use, but this all-metal design eliminates that risk. Every part retains its shape under pressure, so the unit will be physically sound from the day it is installed.
The aluminum alloy and powder-coated steel in the frame really protect it from rust, water, and mechanical stress. The powder coating provides the steel with a hard protective layer that performs well in damp environments like greenhouses and chicken coops. You get a fan that stays rigid, looks clean, and works the same way every time, not one that breaks down after one season.
EC Motor with 1747 CFM Airflow for High-Performance Variable Speed Ventilation
This variable speed shutter exhaust fan has an EC motor that runs at 1600 RPM and draws only 70 watts. With that airflow-to-power ratio, this fan is much more energy-efficient than most AC motors. It quickly and consistently moves large amounts of old, hot, or humid air out of any room at 1747 CFM (2900 m³/h).
With variable-speed control, you can adjust the amount of movement based on the situation, rather than leaving the fan on full power all the time. When it is neither too hot nor too cold, lower speeds make less noise and use less energy. Higher speeds handle peak heat or airflow needs. Because of these factors, the fan is truly adaptable and not just a fixed-output unit that either underperforms or wastes energy.
Temperature and Humidity Controller for Precise Automatic Climate Management
The temperature and humidity controller that comes with it simplifies ventilation management. Once you set your limits, the fan will react by speeding up when conditions get too high and slowing down when the space is stable. This feature keeps greenhouses, garages, and sheds within a steady temperature range without constant adjustments.
When no one is around to stop it, automated control also keeps plants, animals, and sensitive equipment safe from sudden changes in temperature and humidity. The controller keeps an eye on things at all times and turns on the fan before things get worse. When it comes to protecting growers, workshop workers, and animal owners, this level of automated reaction is hard to match with manual switching.
Detachable Steel Mesh Screen for Reliable Protection Against External Debris
With this adjustable shutter exhaust fan from VEVOR, you get an improved steel mesh screen that you can remove and reinstall. This screen keeps bugs, leaves, and other airborne debris from getting into the fan opening. The steel structure of the screen makes it last much longer than plastic mesh screens, which break and sag over time. When left outside, it does not easily lose its structural stability.
The screen connects and detaches without tools, so you can remove it for cleaning or leave it off, depending on your installation. Because the steel edges need care, VEVOR includes safety gloves for handling during installation. This useful feature shows that the product was made to work in real installations, not just in controlled showrooms.
Automatic Louver Shutdown for Efficient Winter Heat Retention
This fan's louvers do more than just guide airflow; when the fan turns off in winter, they automatically close the opening. This feature helps prevent cold air from pushing back through the duct opening and drawing heat from the room. Through open or loosely sealed fan openings, garages and sheds lose a lot of heat that they are trying to keep in. The automatic louver closing stops that loss.
Despite rain, snow, and temperature changes, the case and grille's high-quality materials maintain this sealing ability. The louvers work reliably in bad weather and do not get stuck or warp. You do not have to manually close the fan opening in winter or add extra dampers; the built-in louver system takes care of that for you.
Variable Speed Shutter Exhaust Fan for Versatile Multi-Space Installation
This shutter exhaust fan works well in a wide variety of places, including garages, workshops, attics, greenhouses, chicken coops, sheds, offices, hospitals, and theaters, thanks to its high airflow and quiet operation. As long as you have the right installation thickness clearance, the 406 mm unit can fit standard wall openings. This feature makes the process easier for most types of wall construction.
The 5.9-foot power cord is long enough to connect without an extension cord in most situations. The fan is easy for one person to install since it weighs 10.80 pounds. The product measures 480 mm x 480 mm x 215 mm, which is the right size for standard residential and light commercial wall cutouts. This fan gives you the airflow, control, and build quality you need for many purposes, whether it is a backyard shed or a commercial greenhouse.
