VEVOR Shutter Exhaust Fan, 254mm with Temperature Humidity Controller, EC-motor, 843 CFM, Variable Speed Adjustable Wall Mount Attic Fan, Ventilation and Cooling for Greenhouses, Garages, Sheds

10 Inch Shutter Exhaust Fan with 843 CFM Airflow for Powerful Ventilation 

With 843 CFM (1,400 m³/h) of airflow at 1,650 RPM, this VEVOR 10 inch shutter exhaust fan can quickly remove heat, humidity, smoke, and stale air from enclosed areas. The high airflow helps improve air circulation in enclosed spaces. Even though it has a high output, the unit only uses 18W, making it both powerful and highly energy-efficient for everyday use.

When the fan is off, the auto-closing louvers seal the opening, keeping out cold drafts, bugs, and outside debris. When turned on, the louvers open automatically to let air flow through, so you do not have to adjust them manually. With this passive open-and-close mechanism, the installation is low-maintenance and consistently maintains the barrier between indoor and outdoor areas.

Full Metal Construction with Aluminum Alloy Body for Long-Term Durability 

The new shutter exhaust fan is made entirely of metal. The louvers, mesh cover, fan body, and all the parts that connect them are made of aluminum alloy and powder-coated steel. The all-metal construction maintains its structural integrity in harsh weather conditions, including rain, snow, and high-humidity environments.

Over years of outdoor or partially outdoor use, the powder-coated steel finish adds an extra layer of rust protection, keeping the exterior clean and looking professional. The unit is small enough to place on the wall easily and strong enough to withstand the vibrations of continuous high-speed operation without coming loose or rattling over time. It weighs 6.22 pounds and measures 12.80 x 12.80 x 7.87 inches.

EC Motor at 18W for High Efficiency and Low Energy Consumption 

One big difference between this 10 inch shutter exhaust fan and other AC motor exhaust fans is the electrically commutated (EC) motor inside it. EC motors are naturally more efficient because they convert a larger share of the electricity fed to them into mechanical output, with much less heat and wasted energy. This fan has a better airflow-to-power ratio than AC motors of the same size, even though it only draws 18 W and moves 843 CFM at 1,650 RPM.

The upgraded EC motor also has a longer operational lifespan than regular motors, which means it will need less upkeep and cost less to replace over time. The motor is designed for continuous operation while helping reduce the risk of overheating. This is an important safety feature for places where the fan may run for hours at a time, like gardens, attics, and storage sheds, where no one is around.

Temperature and Humidity Controller for Fully Automatic Operation 

The fan can run on its own based on the current temperature and humidity levels, thanks to the built-in temperature and humidity controls. The user can set specific temperature and humidity levels. The fan turns on when conditions exceed the set levels and turns off automatically when they return to the goal levels. This eliminates the need to manually check and switch, which makes it ideal for places like greenhouses, computer rooms, and storage rooms where stable temperatures are important.

Users can set up both temperature and humidity triggers separately, giving them fine-grained control over when and how the fan responds to environmental changes. With this level of automation, a simple exhaust fan becomes a self-controlling ventilation system.

Variable Speed Control for Customizable Airflow Management 

Users can fine-tune the airflow output to match the unique ventilation needs of their space at any given time by adjusting the speed. Users can also adjust airflow output based on current ventilation needs. It can be turned down when it is cooler or when the space is not being used as much. This reduces noise and energy use while still maintaining proper airflow. This flexibility is especially helpful in places with a lot of noise, like hospitals, businesses, and homes.

With the speed control and the temperature and humidity sensor working together, the fan can adjust its output to match the conditions, rather than just turning on and off at full power. The 5.9-foot (1.8-meter) power cord has enough reach for most standard wall placements, and the unit's simple four-part assembly design means it can be set up and used without any complicated tools or professional help.

Detachable Steel Mesh Screen for Weather and Debris Protection 

The improved detachable steel mesh screen protects against bugs, leaves, external debris, and airborne particles that would otherwise enter through the fan opening. The screen arrives unassembled, so users can choose how to position it to suit their environment. For example, clean indoor installations may not need it, but outdoor-facing installations or those in rural areas will benefit greatly from the extra protection. 

The steel structure of the screen means it will not rust or bend when exposed to the weather over time, unlike plastic mesh screens on other units. The removable design makes it easy to take off for cleaning without taking the whole fan off the wall. This reduces maintenance time and keeps the unit operating at full airflow capacity without debris buildup.

10 Inch Shutter Exhaust Fan Suited for Garages, Greenhouses, and Workshops 

It is possible to install this 10 inch shutter exhaust fan in many different locations. It is suitable for noise-sensitive environments, like hospitals, offices, and bedrooms. Its 843 CFM output is more than enough for workshops, garages, chicken coops, sheds, and attics. 

The standard EC power supply with 220V/50Hz works with European plugs without adapters, and the 1.8m cord gives you the standard installation reach. This VEVOR unit works well as a main ventilation system for a garden that needs to maintain stable humidity or as an extra exhaust unit in a home workshop.
