Product Details
Product Introduction:
Our company’s single‑layer louver diffusers are the most fundamental terminal air supply and exhaust devices in ventilation and air-conditioning systems. They are typically installed at the ends of supply ducts, return ducts, or fresh‑air ducts to evenly distribute airflow and adjust the direction of supply air, and are widely used in indoor air-conditioning and ventilation systems for shopping malls, office buildings, hotels, residential buildings, and other types of structures.
General technical parameters (taking a mainstream aluminum alloy single-layer louvered air diffuser as an example):
| Parameter Item |
Specification Details |
| Product Name |
Single-layer louvered air diffuser (single-layer adjustable louvered air diffuser) |

| Optional Accessories |
Includes a filter screen, airflow control valve, and check valve. |
| Work environment |
-10℃ to +60℃, relative humidity ≤95% (no condensation) |
Applicable Scenarios and Selection Recommendations:
Core use cases:
1. Supply and return air outlets for central air-conditioning systems in shopping malls, office buildings, hotels, and residential buildings
2. Terminal air outlets of the fresh-air and exhaust systems
3. Ventilation exhaust outlets for the underground garage and equipment rooms
4. Air conditioning supply ventilation / Ventilation and air exchange in industrial buildings and workshops
Key considerations for selection:
1. Select based on duct size: Prioritize diffuser sizes that match the duct’s internal diameter to avoid installing reducers, ensuring stable airflow and minimal pressure loss.
2. Select the model based on ventilation requirements: For applications requiring only basic airflow, choose the fixed-blade version; for scenarios where airflow direction needs to be adjusted, the adjustable-blade version is essential.
3. Material Selection: In humid or corrosive environments, aluminum alloy or stainless steel is preferred; for cost‑sensitive applications, ABS plastic may be chosen.
4. Additional functional requirements: When used as a return air grille, it is recommended to equip it with a filter screen to prevent debris from entering the ductwork; when airflow adjustment is required, a flow‑control damper can be installed as an optional accessory.

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.
