It is well known that air conditioning louvers are used in fresh air systems and central air conditioning systems. Air outlets can be categorized by material—such as aluminum alloy, stainless steel, ABS plastic, and steel—or by shape, including square, rectangular, circular, and custom designs. Today, we’ll summarize the common types of aluminum alloy air outlet panels in air conditioning systems and their respective applications.

01 Double-Louvered Air Outlet

Double-louvered air outlets are typically used as supply air vents and can be directly paired with fan coil units. They are widely applied in central air conditioning systems and can be combined with opposed multi-leaf dampers to regulate airflow volume.

02 Single-Louvered Air Outlet Panel

Single-louvered outlets allow adjustment of vertical airflow direction. When used as return air vents, they can be paired with air filters. The louver angle is adjustable, and the blades are supported by ABS plastic brackets. The fixed filter can be easily removed from the track for cleaning and then reinstalled.

03 Fixed Linear Air Outlet

Fixed linear air outlets are used in heating and cooling systems and can be installed on side walls or ceilings. They blend seamlessly with high-end interior decor for an aesthetically pleasing look.

04 Gravity-Louvered Air Outlet

This type automatically exhausts air from positively pressurized air-conditioned rooms. Normally, the louvers close due to gravity, isolating indoor and outdoor air. When indoor pressure exceeds outdoor pressure, airflow pushes the louvers open for exhaust. Conversely, outdoor air cannot flow back inside, functioning as a one-way check valve.

05 Diffuser Air Outlet

Diffusers are common in air conditioning systems, providing uniform airflow distribution and a sleek appearance. They come in square, round, or rectangular shapes to match various ceiling designs.

06 Adjustable Ball-Type Air Outlet

This nozzle-style outlet delivers high-velocity airflow in a specific direction. The airflow direction can be adjusted within a 35° conical range, and the volume can be regulated via a valve. Ideal for large spaces like airport terminals, indoor stadiums, and hotel kitchens.

07 Swirl Air Outlet

Swirl outlets emit rotating airflow with high induction ratios and rapid velocity decay. Suitable for large air volume and temperature differentials, they reduce the number of required vents. Installed on ceilings, they work in spaces as low as 3 meters or up to 10+ meters for extensive coverage.
