1. The double-layer louver tuyere is generally used as an air outlet, and it can also be used directly with a fan coil. It is widely used at the end of a centralized air conditioning system. It can also be opened with a multi-leaf regulating valve to adjust the air volume. 

2. The single-layer louver air outlet can adjust the upper and lower wind direction, the return air outlet can be combined with the air outlet filter, the angle of the segment can be adjusted, and there are ABS plastic fixing brackets between the blades. The fixed filter can be removed from the slide during cleaning, and then pushed in from the slide after cleaning to continue using it.

3. The fixed strip air outlet is used in the heating and cooling air-conditioning system, and can be installed on the side wall or ceiling.

4. Self-hanging louvered air-conditioning room with positive pressure automatically exhausts. Under normal circumstances, the louvers of the tuyere naturally sag due to their own weight to isolate the exchange of indoor and outdoor air. When the indoor air pressure is greater than the outdoor air pressure, the airflow blows the louvers open and exhausts air. On the contrary, when the indoor air pressure is less than the outdoor air pressure, the airflow cannot be reversed. Into the room, the tuyere has a one-way check.

5. Diffusers are commonly used air outlets in air-conditioning systems. They have uniform diffusive characteristics and a simple and beautiful appearance. They can be made into squares or rectangles according to the requirements of use, and can meet any ceiling decoration requirements. The inner core part of the diffuser can be detached from the outer frame for easy installation and cleaning. The rear can be equipped with a tuyere regulating valve to control and adjust the air volume. Suitable for broadcasting studios, hospitals, theaters, classrooms, concert halls, libraries, amusement halls, theater lounges, general offices, shops, hotels, restaurants, and gymnasiums, etc. In order for people to avoid noise interference and discomfort in various environments, in addition to determining the neck wind speed according to the performance table, it is also necessary to consider the installation height and installation occasion.

6. The spherical adjustable tuyere is a nozzle type air outlet. The high-speed air flows through the nozzle of the valve body to the specified direction. The direction of the air jet can be easily adjusted in a conical space with a top angle of 35°. The flow rate can also be adjusted by the valve opening and closing degree. It is used in occasions where high-speed air supply or local cooling is provided on the top of tall floors, such as airport waiting halls, indoor stadiums, hotel kitchens, etc. 

7. The swirling air outlet sends out a rotating jet, which has the characteristics of large induction ratio and fast wind speed attenuation. It can be used for large air volume in air conditioning and ventilation systems, and large temperature difference air supply to reduce the number of air outlets. It is installed on the ceiling or ceiling and can be used for 3 For low space within meters, two types of heights can also be used for large-area air supply, even up to 10 meters in height.
