The coating of the secondary air oxidation surface layer of the aluminum alloy air terminal unit is constructed of all aluminum alloy profiles and is defined by stainless steel plates when the light source enters into different transport chemical substances. The electric welding thick steel plate material with hot-dip or cold treatment layer on the surface layer is waterproof, rainproof and fireproof. The aluminum alloy air inlet can be used in all climatic conditions and can be assembled into a louver with overall planning to achieve large total gas flow and harmonious noise elimination, The movable blade of the theme is of the linear type, and the silencing material is embedded between the blades. The wide application of aluminum alloy air terminal units promotes the development trend of aluminum alloy welding technology. Meanwhile, the development trend of welding technology expands the main use of aluminum alloy air terminal units. Therefore, the welding technology of aluminum alloy profile is becoming one of the focuses of scientific research.

Because all the materials of aluminum alloy air terminal units are made of high-quality aluminum alloy profiles, combined with the special manufacturing process, the silencing louvers can be applied under all climatic conditions. The deformation of the aluminum alloy air terminal unit's bottom outer frame and the louver sheet can effectively avoid the deformation of the top outer frame, the bottom frame, the louver sheet and the outer frames on both sides. Waterproof and rainproof louver aluminum alloy air terminal units are one of air diffusers.

In air conditioning equipment, many types of aluminum alloy air inlets and aluminum alloy air inlets are commonly referred to as air diffusers. The common louver aluminum alloy air terminal units include single-sided louver aluminum alloy air terminal units, two-layer louver aluminum alloy air terminal units, outer wall grid aluminum alloy air terminal units and slot type grid aluminum alloy air terminal units. The aluminum alloy air terminal units can greatly reduce the cyclone transmission friction resistance and attenuate the noise. The aluminum alloy air terminal units of standard size are assembled into a series of products according to the displacement coefficient array. According to the demand, the silencing louver is painted with various colors on the surface of the silencing louver.

Before the equipment of aluminum alloy air terminal units, it is required to check the mechanical energy of aluminum alloy air terminal units. The theme movable parts of aluminum alloy air terminal units have easy posture, uniform vibration reduction, and no jamming and looseness. The drainage sheet is a commodity that can be scheduled or allowed to be disassembled. It is specified that the scheduled disassembly is convenient and reliable, and the aluminum alloy air terminal units is not easy to lose after positioning. The indoor decoration surface of the aluminum alloy air terminal units surface shall be leveled, the blades shall be evenly distributed, the natural color tone shall be consistent, and there shall be no significant scratches and impressions. The allowable error value of aluminum alloy air terminal units shall also comply with the standard provisions in the work. When installing aluminum alloy air terminal units, the actual operation shall be carried out according to the corresponding regulations.

As you can see, the materials of the aluminum alloy air outlet mainly include steel and aluminum alloy profiles. The actual materials can be based on your main regulations. The main performance indicators of the aluminum alloy air outlet adopted by you are the form, material, standard, inlet, and outlet wind force, motor-rated power discard, and cyclone effective range. What kind of louver is actually used, whether it is straight or other, depends on the type of natural ventilation, dispatching function and exhaust mode, etc. to select the corresponding aluminum alloy air terminal units The specification shall be determined according to the required exhaust volume [exhaust or supply air, within the allowable wind force range at the head neck of aluminum alloy air terminal units or the cross-section of the import and export trade of aluminum alloy air terminal units.
