Product Details
Product Overview:
Our company manufactures haze‑removal ventilation fans—also known as duct‑type fresh‑air purification fans or haze‑removal fresh‑air units—which are duct‑mounted systems that combine low‑noise air supply, air filtration and purification, and intelligent control. Building on the foundation of quiet operation, these units integrate an air‑filtration module that efficiently removes particulates such as PM2.5, dust, pollen, and allergens from outdoor air. Simultaneously, a low‑noise fan delivers the purified, fresh air into indoor spaces. Certain models further offer features like airflow‑rate adjustment and timed operation via a controller. Widely deployed in residential, office, and commercial settings as part of fresh‑air systems, they serve as a core solution for improving indoor air quality during hazy and polluted conditions.

Note: The filter can be upgraded to an H11/H13‑grade HEPA filter upon request, delivering even higher levels of purification; some models feature a brushless DC motor, resulting in lower noise and reduced energy consumption.
Scope of Product Use:
1. Residential scenarios:
A home ventilation system addresses indoor PM2.5 levels that exceed safe limits during smoggy weather, delivering clean, fresh air while operating quietly to ensure an unimpaired living experience.
Commercial office settings: Fresh-air systems for office buildings, meeting rooms, hotel guest rooms, and private dining rooms ensure indoor air quality and enhance comfort in both work and living environments.
2. Public Building Scenarios:
In school classrooms, libraries, hospital wards, nursing homes, and other settings, removing particulate matter and allergens from the air helps reduce the risk of cross‑infection.
3. Special Use Cases:
For spaces with stringent air quality requirements—such as nurseries, studies, and precision instrument rooms—it delivers highly purified supply air; it can also be used for ventilation, deodorization, and air purification in damp areas like basements and storage rooms.
4. Urban renewal project scenarios:
No extensive ductwork is required; it can be directly installed within existing ventilation ducts, enabling fresh-air purification and upgrading of older homes and buildings.

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.
