The design of the DOP HEPA box is very different from that of the circular HEPA box

(1) DOP HEPA box: Unique liquid tank is exquisite
The overall shape of the DOP HEPA box is relatively regular, and it is mostly square box structure, giving people a simple and tough feeling. Its most significant appearance feature is the liquid tank surrounding the border of the high-efficiency filter, which is usually a groove of moderate width and uniform depth, like a carefully inlaid "moat". This liquid tank is generally located at the side of the air supply port near the air outlet. When the filter is installed, the fluid tank is closely fitted with the filter frame to form a sealed connection. From the material point of view, the liquid tank part is mostly made of metal material suitable for the box, and the surface is smooth and flat after fine processing, which not only ensures tightness but also shows exquisite technology. In some large clean workshops, rows of DOP HEPA boxes are arranged neatly on the ceiling with their unified appearance design, showing a beauty of order. Close observation, you can also find that the electrostatic spray treatment on the surface of the DOP HEPA BOX box not only has a delicate touch, but also has good corrosion resistance, effectively resists environmental erosion, and maintains a new appearance for a long time.
(2) Circulation HEPA box: annular wind has characteristics
The circulation HEPA box breaks the square pattern of the traditional tuyere and takes the ring as the main design element, which is unique. From the appearance, it looks like a "doughnut" suspended in the air, the outlet is evenly distributed in a ring around the central air intake area. This unique ring structure allows the airflow to spread from the center to the periphery of a ring, forming a unique airflow organization form. Compared with ordinary round or square tuyere, circulation HEPA box is more three-dimensional and hierarchical. Its shell materials are diverse, common aluminum alloy, ABS plastic, etc., while meeting the strength requirements, taking into account lightweight and beautiful. The circulating HEPA box made of aluminum alloy is anodized to show a metallic luster and full texture. The ABS plastic material has good insulation and machinability, and can easily achieve a variety of color matching to meet the needs of different decoration styles. In some high-end hotel lobbies, modern art galleries, and other places, circulation HEPA boxes as part of the space decoration, with their unique shape, complementing the surrounding environment and adding a sense of technology and fashion to the space.
