1. Why does a Kitchen need a Wall Exhaust Fan?
Installing an exhaust fan in the kitchen is essential, as daily cooking and activities inevitably generate cooking fumes, odors, and even harmful gases that can negatively impact users’ experience.
A kitchen wall exhaust fan effectively addresses these issues by drawing in and filtering odors or harmful gases through airflow. These substances are then expelled outdoors via connected ductwork, purifying indoor air. This makes it a common fixture in kitchens.
Aosun possesses specialized expertise in fan manufacturing. From raw materials to final inspection, we rigorously enforce comprehensive quality control throughout the entire process, ensuring we provide reliable products to support your business.
2. Factors to Consider When Buying a Wall Exhaust Fan for the Kitchen?
2.1. Airflow Rate
When purchasing kitchen wall exhaust fans, one parameter you need to consider is the fan’s CFM. This typically represents the ventilation volume per minute.
Calculating CFM is an essential step in selecting equipment, requiring consideration of specific factors. For instance, if your stove measures 35 inches, the required CFM should not fall below 292 CFM. The calculation follows this logic: 35 inches = 2.92 feet, so the rated airflow is determined by multiplying 2.92 feet by 100 CFM.
When further accounting for kitchen size and usage frequency, the rated CFM value should be higher to meet specific requirements.

2.2. Space Occupancy
The wall-mounted design ensures that kitchen wall exhaust fans do not occupy excessive floor space, thus avoiding disruption or inconvenience to daily activities. This is one reason for their widespread adoption. Users prefer space-saving exhaust fans for everyday use, and you should also recognize that compact devices will be more popular to support your business.
2.3. Operating Noise
Operating noise is another factor of concern for most users. The sounds produced by various devices in daily life can contribute to noise pollution, affecting your hearing and even your daily activities. Therefore, kitchen wall exhaust fans with low operating noise have become the preferred choice for many users.
Generally, a noise level of 30–40 decibels is considered relatively quiet for a normal environment. Aosun ‘s kitchen wall exhaust fan operates at 31 dB(A).

2.4. Power Consumption
Similar to selecting other household electronics, power consumption is a factor to consider. Generally, kitchen wall exhaust fans with power ratings between 30W and 60W can meet normal usage requirements while operating within an acceptable decibel range, making them suitable for both residential and commercial kitchens.
2.5. Ease of Installation
Installation convenience is another key advantage of kitchen wall exhaust fans. Models featuring drilled holes simplify the installation process, making them the preferred choice for most users. This factor should also be considered.
Aosun ‘s kitchen wall exhaust fans come with tight fitting square or round cover plates that easily accommodate standard 6-8 inch ducting, further streamlining the installation process.
3. How to Install an Exhaust Fan on the Kitchen Wall?
3.1. Inspection before the Installation
First, you need to verify that all fan components are complete and secure, and pay attention to the position of the air outlet during the installation, ensuring it is placed as far as possible from oversized equipment.
3.2. Installation
The second step is installation. Here, you should ensure the fan remains stable and vertical to the floor. After tightening the bolts, you can check for a tight seal between the fan and the wall surface. If gaps exist, you need to fill them with adhesive material to ensure proper sealing and stable performance during subsequent use.
3.3. Test Run after the installation
Once the kitchen wall exhaust fan is fully installed, it’s time for you to take a thorough inspection to ensure no debris remains inside the fan, such as tools used during installation.
Then you can take a test run. If no abnormalities occur, the fan is ready for normal use. However, if unusual noises are detected during the test run, you must immediately halt the equipment and conduct an inspection. This inspection should include determining whether the issue stems from the product itself or previous improper operation.
4. How to Choose the Proper Manufacturer for the Kitchen Project?
When selecting a reliable manufacturing partner, you should also consider factors such as operational experience and qualifications. A factory with extensive production expertise typically possesses deep knowledge in manufacturing kitchen exhaust fans, ensuring you receive products with reliable performance.
Additionally, you need to verify whether the purchased products have passed the safety certifications, such as CE, UL, ASTM, ISO, and other international standards, to further meet your requirements for safety and harmlessness.

The best installation location for the Kitchen wall exhaust fan is to near the stove, against the exterior wall, and staggered with the range hood, ensuring that there is fresh air supply.
To maximize the efficiency of the ventilation fan,below principles can be followed:
1. Near the source of oil fume production (above or on the side of the stove).
2. Installed on the exterior wall to ensure air exhausted directly outside.
3. Position offset from the range hood (such as diagonal wall).
4. Usually installed on 1.8-2.0 meters above the ground (wall mounted)or close to the ceiling position.
When using the exhaust fan, we should pay attention to its placement to avoid connecting the ventilation duct to areas like the attic. Not only will this fail to achieve effective ventilation, but it will also compromise the air quality in these indoor spaces.
Choose aluminum alloy blades or plastic blades depends on different scenarios you are using.
If you have heavy cooking fumes, frequent stir frying, and high smoke exhaust requirements like stir frying or frying, it is recommended to choose aluminum alloy blades. Because of its large air volume, stability, high temperature resistance and good durability, it is more suitable for high load and high-frequency use.
If you have a small kitchen, light cooking (steaming, low oil fume), sensitive to noise, or limited installation conditions ,budget, plastic blades would be more suitable as they are lightweight, silent, moisture resistant, and affordable.
If your kitchen environment is humid, with oil mist and steaming, plastic blades is good choice as they have better corrosion and moisture resistance.
Yes,they can be used together but avoid interference between the two air ducts. The correct way is to use the range hood as the main suction and the ventilation fan as an supporting exhaust.
Below are some key points to be noticed:
1. Both range hoods and kitchen ventilation fans require air replenishment to create a continuous airflow.
2. First turn on the range hood, then turn on the ventilation fan to avoid oil fumes from being carried away and spread by the ventilation fan before they are collected.
3. After cooking, the ventilation fan can be turned on separately for 5-10 minutes to accelerate odor dispersion and remove moisture.
To ensure its sealing, we should notice following aspects:
1. Accurately measure the size of window openings. Measure the width, height, and depth of the window opening. The size of the ventilation fan should be as close as possible.
2. Use appropriate sealing materials,such as foam sealing strip,
silicone sealant or glass adhesive,waterproof sealing tape.
3. Ensure that the window frame is tightly attached to the fan frame.
4. Check the connection between the glass and the frame. Seal the edges tightly with transparent glass adhesive.
5. Regularly check the aging condition of the sealing strip.
Due to sunlight or rain,the sealing material may age and should be checked every 1-2 years and replaced if needed.
There are some common reasons such as clogged grilles, poor sealing, or insufficient current, which require regular cleaning and inspection of the circuit.
You can troubleshoot from following issues:
1. Motor aging or is damaged;
2. Worn bearings;
3. Insufficient voltage;
4. Ventilation duct blockage;
5. Blockage of filter or protective net cover.
Yes. There is detachable or reversible designs,they are designed specifically to accommodate window openings and do not require permanent structural modifications.
For kitchen wall exhaust fan, it directly fixed on the window frame, requires cutting holes that match the size of the exhaust fan, and after installation, the gaps need to be sealed to prevent mosquitoes from entering.

Kitchen ventilation fan blades can accumulate oil stains after long time running.It’ll affect air flow, increase noise, and even shorten their lifetime if not cleaned regularly. Below are some safe and effective tips for cleaning:
1.Cleaning frequency, recommended to clean the baldes every 1-2 months,together with filter or shell.
2.Before cleaning,cut off power of ventilation fan or unplug it to ensure safety.
3.Remove Blades and wash it.Use screwdriver to remove the blade.Then use warm water and oil stain cleaner to clean it.
4.After drying,inspection motors and install it back.
High summer temperatures have some effects on exhaust fans in the following aspects:the air volume, efficiency, noise, lifetime, etc.
In a high temperature environment, the fan motor itself will generate heat if the kitchen temperature is very high,motor cooling is slower,exhaust effect is weaker.
In summer time oil are more easily attached to the blade,vent and filter which resulting in a decrease in the actual air volume.
So in order to get more effectively use,it’s better to do cleaning,cooling and maintaining ventilation fans.
To judge if fan motor is damaged,we can tell from several aspects such as sound,speed,current,odor,temperature, etc. You can investigate as below steps:
1.First confirm that the power supply is normal,there is no loose wiring.
2.Seconldy check if the blades are stuck by oil, rotate gently.
3.Thirdly listen to the sound: if buzzing but not spinning, then 90% is a capacitor issue.
4.Then check if the capacitor is broken(the most frequently damaged component).
5.Check if the motor is overheating or has a burnt smell.
If still unable to recover then the motor coil is damaged and needs to be replaced.
