It features a slim, modern design ideal for sites with limited space or aesthetic requirements.
Why Open Doorways Need Insect Control?
Business and industrial sites are facing a challenge: busy entrances and exits cannot remain closed continuously. Due to the frequent movement of employees, goods, and forklifts, the doors must remain open, resulting in the building entrances being exposed to the external environment throughout the operation period. Open and unprotected doorways become direct entry channels for various harmful external substances, including flying insects and external air pollutants.
For places that prioritize hygiene standards and logistics management, the entry of flying insects will pose significant risks, such as affecting hygiene standards, product contamination, decreased customer experience, and increasing the burden on facility management. Our insect control air curtains are specifically designed to precisely control the invasion of flying insects into open areas, allowing for the continuous operation of the site while effectively preventing flying insects from entering.
What Factors Make an Air Curtain Effective for Insect Control?
An efficient insect control air curtain does not rely on simple air flow output, but forms a stable protective barrier at the door opening, which actively prevents flying insects from entering the indoor space.
Airflow Velocity
Sufficient and stable airflow velocity is the core of the insect prevention. The airflow gradually weakens as it moves downward. Higher doors require enhanced air curtain power and initial wind speed to ensure that the air flow maintains an effective insect prevention speed when reaching the lower door opening and ground area.
Full Doorway Coverage
The length of the air curtain device must match the width of the door opening exactly. If there are uncovered gaps on both sides of the door passage, they will become passageways for insects to enter. It will damage the integrity of the protective barrier.
Installation Height
The equipment is directly installed above the door, leaving a minimum gap between it and the door opening. This can reduce air flow dispersion and loss. A reasonable installation position can ensure the concentrated output of airflow and maximize the protection efficiency.
Site Conditions
Outdoor wind force, the pressure difference, and frequent vehicle passage will all affect the stability of the air flow. High-quality fly air curtains are specially designed to withstand these on-site disturbances and can maintain stable blocking performance.
Appilication of Insect Control Air Curtains
Our insect control air curtains have been optimized for industrial and commercial scenarios, providing targeted insect prevention capabilities:
Food Processing Facilitiy
Suitable for production areas, packaging zones, and raw material intake ports. These areas have strict hygiene standards and are frequently accessed by logistics vehicles and personnel. The air curtain can keep the operation flow unobstructed while effectively blocking flying insects and preventing contamination of raw materials and finished products.
Restaurants and Commercial Kitchens
Perfect for rear service doors, kitchen entrances, and delivery entrances. During peak business hours and during food delivery periods, these doorways are often fully open, thus increasing the risk of insect intrusion. The air curtain barrier can effectively block insects that attract odors, while not affecting daily operational efficiency.
Supermarkets and Food Retail Stores
It is suitable for the main entrance, the rear loading and unloading door, and the food processing area inside the store. It can effectively protect fresh food display cabinets, cooked food counters, and retail environments from flying insects, ensuring a clean shopping environment and consumer food safety.
Warehouses and Distribution Centers
Frequent cargo transportation and forklift operations make it impossible to keep doors closed all the time. Fly control air curtains can provide a stable barrier performance throughout the day to prevent outdoor insects from invading stored goods and ensure that inventory remains clean and undamaged during inbound and outbound logistics operations.
Refrigeration and Freezing Facilitiy
Designed specifically for the entrances of low-temperature freezer, it combines reliable insect prevention functions and indoor/outdoor air isolation functions. For refrigerated and cold-storage entrances, the air curtain can also help reduce unwanted air exchange while supporting insect control.
General Manufacturing Facilitiy
Suitable for production workshops and clean industrial areas that require strict cleanliness, dust prevention, and insect prevention. The air curtain can reduce insect interference in the production environment, reduce dust entry, and maintain standardized production hygiene conditions.
How to Choose an Insect Control Air Curtain?
The following selection guide can help you match the most suitable insect control air curtain for the site, avoiding incorrect selection.
Measure the Width of the Door
The width of the air curtain must completely cover the entire door opening. For extremely wide entrances, if a single air curtain cannot cover it, multiple air curtains can be installed side by side to achieve seamless coverage.
Confirm the Actual Installation Height
You need to match the corresponding air flow speed and air volume parameters based on the actual height of the door opening. Higher installation heights require stronger initial air flow energy to ensure the ability to effectively block insects.
Frequency of Door Opening
High-frequency opening scenarios require the air curtain to operate continuously and stably for a long time. You should choose a heavy-duty industrial-grade air curtain model for such scenarios. Low-frequency opening scenarios can use a conventional optimized configuration.
Evaluate Indoor and Outdoor Environmental Conditions
Evaluate the interfering factors at the site, including strong outdoor cross winds, significant indoor-outdoor pressure differences, and temperature differences. For places severely affected by the environment, enhanced wind resistance performance and customized wind speed calibration are required.
Installation Guide for Better Insect Control
Correct installation is crucial for ensuring the effectiveness of the air curtain in controlling mosquitoes. You need to follow the following basic principles to avoid performance degradation due to improper installation:
Install Close to the Door Opening
When installing, you need to minimize the gap between the air curtain outlet and the door opening to reduce air flow dispersion and energy loss, and ensure that the air is delivered vertically in a concentrated and uniform manner.
Ensure Full Coverage of the Inlet Width
Avoid having left or right blind spots when installing the air curtain. Full coverage can eliminate edge gaps and prevent insects from entering.
Maintain a Reasonable Air Flow Direction
Slightly tilt the air flow outward to counteract outdoor air intake and wind pressure, and enhance the mosquito repellent effect.
Remove All Air Flow Obstructions
You need to ensure that door frames, hanging signs, ceiling structures, and other obstacles are far away from the outlet to ensure smooth air flow and uniform output.
Adjust the Airflow Speed
Where site conditions require it, the discharge angle may be adjusted slightly outward to help counter external airflow. Final adjustment should follow the product specification and site conditions.
Yes. The air curtain is the protective measure at the entrance, while the insect light traps manage the existing pests in the indoor area. These two can form a complementary pest control system rather than one having to be chosen over the other. The dining establishment pest control guidelines usually also combine porch prevention with indoor trapping.

The air curtain cannot achieve 100% complete prevention of insects from entering the room. It relies on a high-speed air barrier to significantly reduce the probability of insect invasion. However, in unfavorable site conditions, there is still a possibility of a few insects passing through. We recommend that you use the air curtain as part of an insect control plan and use it in conjunction with other pest control measures.
The air curtain mainly interferes with the flight paths of insects, and is suitable for driving away flying pests that enter the room by flying: flies, mosquitoes, small moths, fruit flies, and various flying pests of this kind. However, it has no protective effect on crawling insects such as cockroaches.
The insect control air curtain is specifically designed for food processing workshops, kitchens, and food preparation areas in supermarkets. Unlike chemical pest-control methods, an air curtain creates an airflow barrier without applying pesticides at the doorway. The installation must still comply with applicable food hygiene requirements and should not direct contaminated air toward exposed food.
When the door opening is in an open state, it is recommended that the air curtain remain continuously running. If the door is closed, the equipment can be turned off. If the entrance remains open for a long time, the air curtain should continue to operate during this period. In appropriate circumstances, the use of door switches or automatic control systems can be employed.
The cleaning cycle depends on the usage environment:
In food workshops and commercial kitchens: Check and clean the air vents and impellers monthly.
In warehouses and ordinary commercial entrances: Clean once every 2 to 3 months.
For dusty and highly oily environments, it is recommended to shorten the cycle.
Oil stains and accumulated dust will directly reduce the insect-control performance. Dust and oil adhering to the impeller and the air outlet will alter the air velocity and the uniformity of the airflow, causing local air flow to be weaker, creating weak points where insects can easily enter. In severe cases, excessive oil and dust accumulation will also pose hygiene risks, especially in food-related places where the risks are even higher.
Several points can be used to determine the operating condition of the equipment:
Visual inspection: The air flow from the outlet completely covers the entire width of the door opening, and the air flow can reach the lower part near the ground of the door opening without any local interruption or deviation.
Measured wind speed: The wind speed at the critical height position meets the pest prevention design requirements.
On-site phenomenon: When the door opening is open, the number of flying insects invading the indoor area significantly decreases.
Equipment status: The fan has no abnormal noise, and the outlet is not blocked by dust or oil stains.
No, it is not very necessary. The air curtain will form a complete and powerful air barrier. It offers superior insect-proof, dust-proof, and heat-insulating effects compared to traditional door curtains, and it will not obstruct customers from entering or exiting. At the same time, it can save on the cost of replacing door curtains.
