China Clean Booth in Clean Class 100 | High-Quality Suppliers & Factory Solutions for Effective Air Purification
Widely used in electronic component assembly and inspection, localized sterile operations in pharmaceuticals and laboratories, PCB and SMT production lines, precision instrument and optical product assembly, and filling and inspection areas in the food and cosmetics industries.
This is the "skeleton" of the clean booth, determining its overall shape, size, and stability.
Industrial Aluminum Profiles: The most mainstream and common choice. Typically high-quality aluminum alloy (such as 4040 or 4080 profiles) with an anodized surface finish. They offer lightweight, high-strength, corrosion-resistant, and aesthetically pleasing properties, and are easy to assemble and disassemble.
Stainless Steel: Primarily used in applications with extremely high requirements for cleanliness, corrosion resistance, or structural strength, such as in certain biopharmaceutical or food industries.
✦ Modular Design: The frame uses standardized components and connectors, allowing flexible assembly into booth bodies of different sizes (length, width, height), offering excellent scalability and adaptability.
✦ Stability: Ensured through the use of reinforcing struts, leveling feet, or floor anchoring to prevent shaking caused by fan vibration or personnel contact.
These are the "walls" that form the enclosed space of the clean booth, directly impacting the sealing of the clean area and the maintenance of cleanliness.
Color Steel Sandwich Panels: The most common material, typically consisting of steel sheets on the outside filled with core materials like Polystyrene (EPS), Polyurethane (PU), or Rock Wool. Rock wool color steel panels are widely used for their excellent fire resistance.
Tempered Glass: Often used for side or front panels, providing good visibility for observing internal operations. Can be fully transparent or frosted.
Acrylic Sheets: Serve as a lower-cost transparent material option, but with less strength and durability compared to tempered glass.
Panels are connected via specialized tongue-and-groove joints, with sealant applied strictly at the seams to ensure the booth is airtight, preventing the ingress of external contaminants.
This is the "heart" of the clean booth — core to creating the clean environment.
✦ FFU (Fan Filter Unit): The most critical component of a clean booth. It is a modular unit integrating a HEPA filter and a fan. FFUs are installed on the ceiling grille of the booth structure.
✦ Fan: Provides the power for air circulation, pushing clean air downward from the FFU.
The most common form. FFUs are installed on the top, causing clean air to flow vertically downward like a piston, carrying away contaminants. Air is returned through bottom or side return air panels, passes through pre-filtration, and is drawn in again by the FFU fan through the HEPA filter — forming a complete cycle.
FFUs are installed on the side, causing air to flow horizontally across the work area. Suitable for certain specific process requirements.
