Product Details
Product Introduction:
The through‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a transverse‑flow fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a slim, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Main functions of the Products:
High-efficiency thermal insulation and energy saving: It creates a continuous, uniform air curtain at the doorway that prevents convective heat exchange between indoor and outdoor air, effectively reducing energy consumption for air conditioning and heating—typically cutting energy losses through the entrance by 30% to 50%.
Dust-proof, insect-proof, and odor-proof: It prevents outdoor dust, vehicle exhaust, pollen, flying insects, and unpleasant odors from entering, keeping indoor spaces clean and comfortable—making it especially well-suited for the exterior doors of food stores, restaurants, and cleanrooms.
Heated and cooled air curtains enhance comfort: Electric‑heated models deliver a warm air curtain in winter, counteracting cold drafts and raising the perceived temperature in the entrance area; hot‑water and chilled‑water systems provide cooling in summer and heating in winter, creating a thermally balanced transition zone; natural‑ventilation models enhance air circulation.
Ultra-thin design saves space: The unit typically measures just 170–230 mm in thickness and is lightweight, allowing it to be mounted flush against the ceiling or wall without encroaching on headroom or obstructing the opening and closing of fire‑rated rolling shutters and door leaves.
Low-noise, silent operation: The through-flow fan features minimal airflow pulsation and low vortex noise; paired with a quiet motor, it produces virtually no wind noise at low speeds, making it ideal for quiet environments.
Uniform air curtain with no blind spots: The full-width through-flow impeller, combined with a precision‑designed airflow duct, delivers a consistently uniform air velocity along the entire length, ensuring complete curtain coverage without creating cold‑hot streaks, and providing superior sealing performance compared to multi‑point blowers.
Convenient Control and Energy-Saving Integration: Standard features include remote or wired control, with three fan speed settings—high, medium, and low. An optional magnetic door switch is available, enabling the unit to start when the door opens and delay shutdown when the door closes, further enhancing energy efficiency.

Cross-flow air curtain machine
The cross‑flow air curtain employs a large‑diameter, slender cross‑flow impeller—also known as a tangential fan—directly driven by a single‑phase motor to generate a wide, planar, high‑velocity airflow. It is installed above or on the side of doorways. The unit features a flat, rectangular profile with a much reduced depth compared to centrifugal models, allowing it to seamlessly integrate into various ceiling designs. It is particularly well suited for spaces with limited headroom and where aesthetics and quiet operation are paramount, such as shopping malls, supermarkets, restaurants, office buildings, banks, hospitals, and residential garages.
Our company’s surface-type coolers are among the core heat-exchange devices in air-conditioning and ventilation systems. They are primarily used to cool and dehumidify air, and can also be switched to hot-water or steam mode during winter to provide air heating. By utilizing a refrigerant (such as chilled water, refrigerant, or brine) or a heat-transfer medium (such as hot water or steam) flowing inside the tubes, these units facilitate forced‑convection heat exchange with the air flowing outside the tubes, thereby regulating air temperature and humidity. As the central heat-exchange components of chiller units, fresh-air handling units, fan coil units, and other equipment, they offer high heat-exchange efficiency, flexible installation, and broad compatibility.
The ceiling‑mounted fresh air ventilator (ceiling‑type air handling unit) is a central air‑conditioning terminal unit that integrates fresh air exchange, air temperature and humidity control, air filtration and purification, and energy recovery. The unit features a concealed ceiling‑mount installation, suspended within the building’s suspended ceiling. It utilizes chilled water or hot water piping to provide cooling and heating, while simultaneously exhausting indoor stale air and supplying filtered outdoor fresh air. This system not only enhances indoor air quality in enclosed spaces but also regulates air temperature through heat‑exchanger coils, offering both ventilation and central air‑conditioning functions. It delivers energy savings, minimizes floor space occupation, and is widely suited for integration into fresh air systems in commercial, industrial, and large public buildings.
Our company’s Q‑type air heater is an industrial‑grade, forced‑convection heating unit that uses water or steam as the heat transfer medium. It is specifically designed for large‑space applications such as factory and mine workshops, warehouses, large buildings, and drying rooms. The equipment consists of a fan, an electric motor, and a steel finned‑tube radiator integrated into a single unit. Performance tests have demonstrated its stable and reliable operation. By combining “steam heat exchange with forced air supply,” it rapidly heats the air, delivering highly efficient heating and making it one of the mainstream solutions for heating high‑ceiling spaces.
