4-way Square Ceiling Diffuser

4-way square ceiling diffuser is the most widely used ceiling air supply terminal device in central air conditioning ventilation systems. It is installed on the indoor ceiling, and delivers the concentrated air flow from the air duct evenly to the surroundings in four directions. Through strong induction, it quickly mixes indoor air, making the supply air temperature quickly approach room temperature, avoiding cold air direct blowing, and ensuring uniform and comfortable air speed and temperature in the indoor working area. 4-way square ceiling diffuser has a simple and square appearance, with good adaptability to ceilings, and is the mainstream choice for ceiling air supply in various commercial and public buildings.

Our 4-way square ceiling diffuser is made of high-quality aluminum alloy or galvanized steel sheet. The blade structure is optimized by fluid dynamics design, with high air supply induction ratio and good mixing effect. The air speed in the working area is lower than 0.25m/s, without obvious blowing feeling. The product adopts standard square size, can directly adapt to conventional ceiling modules, with convenient installation and flat and beautiful appearance. With 23 years of manufacturing experience in ventilation terminal equipment, our four-way square ceiling diffuser has high processing precision, uniform and symmetrical blades, smooth air outlet and low noise. It can stably adapt to various central air conditioning systems, providing comfortable and uniform air supply experience for indoor spaces.

• Commercial buildings: Various ceiling air supply scenarios such as office buildings, conference rooms, shopping malls, and hotel lobbies
• Public facilities: Air conditioning air supply in public buildings such as hospitals, schools, libraries, and exhibition halls
• Industrial scenarios: Places with high requirements for air supply uniformity such as electronic workshops, laboratories, and data centers

We have a 13,000-square-meter self-built production workshop, equipped with a full set of air outlet production equipment such as CNC bending machines, laser cutting machines, and punching machines. The monthly production capacity of air outlet products can reach 1,000 units. Founded in 2003, the factory has been deeply engaged in the field of ventilation terminal equipment for 23 years. We have a professional production and R&D team. The diffuser products are optimized by fluid dynamics design with excellent air supply performance. We have mature mass production capacity and keep stock of common sizes, which can quickly respond to bulk procurement needs of various engineering projects.

We have established special quality inspection standards for air outlet products. From raw material incoming inspection of material and surface treatment quality, to sampling inspection of dimensional accuracy, blade gap and symmetry during production, to appearance inspection and air supply performance sampling inspection of each 4-way square ceiling diffuser at the finished product stage, we ensure uniform air supply and flawless appearance. 100% full inspection is implemented before packaging to ensure standard product size and good installation adaptability. We support on-site inspection by third-party institutions. The products come with a one-year warranty upon delivery, with stable and reliable quality.

In view of the characteristics of diffusers being easy to scratch and deform, we adopt special protective packaging. Each product is individually bagged, with protective film covering the surface and buffer material filled inside to prevent collision, scratch and extrusion deformation during transportation. Layered spacers are used for multi-piece packing to avoid mutual friction damage between products. We support multiple trade terms such as EXW, FOB, DDP. The standard production cycle of standard products is about one week, and batch orders can negotiate production scheduling to ensure intact delivery of products.
