    Product Details

    Application Area
    Electronic Components Pharmaceuticals & Labs PCB & SMT Lines Precision Instruments & Optics Food & Cosmetics Filling
    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.
    Clean Laminar Flow Hood Structure
    1. Main Frame Structure

    This is the "skeleton" of the clean booth, determining its overall shape, size, and stability.

    Industrial Aluminum Profiles

    The most mainstream choice — high-quality aluminum alloy (e.g., 4040 or 4080 profiles) with anodized surface finish. Lightweight, high-strength, corrosion-resistant, aesthetically pleasing, and easy to assemble/disassemble.

    Stainless Steel

    Used in applications requiring extremely high cleanliness, corrosion resistance, or structural strength — such as in bio-pharmaceutical or food industries.

    Design Features
    Modular Design

    Standardized components and connectors allow flexible assembly into booth bodies of different sizes (length, width, height) with excellent scalability and adaptability.

    Stability

    Ensured through reinforcing struts, leveling feet, or floor anchoring to prevent shaking caused by fan vibration or personnel contact.

    2. Enclosure Panel Structure

    These are the "walls" that form the enclosed space of the clean booth, directly impacting the sealing of the clean area and maintenance of cleanliness.

    Color Steel Sandwich Panels

    The most common material — steel sheets filled with EPS, PU, or Rock Wool cores. Rock wool panels are widely used for 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

    A lower-cost transparent material option, but with less strength and durability compared to tempered glass.

    Connection Method: 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.

    Air Filtration System
    This is the "heart" of the clean booth — the core to creating and maintaining a clean environment.
    Core Components
    FFU (Fan Filter Unit)

    The most critical component of a clean booth. A modular unit integrating a HEPA filter and a fan, installed on the ceiling grille of the booth structure.

    Fan

    Provides the power for air circulation, pushing air downward from the FFU to maintain continuous clean airflow throughout the booth.

    Airflow Patterns
    Vertical Laminar Flow

    The most common form. FFU 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 — forming a complete cycle.

    Horizontal Laminar Flow

    FFU are installed on the side, causing air to flow horizontally across the workspace. Suitable for certain specific process requirements where vertical flow is not ideal.

    Frequently Asked Questions
    Q What industries commonly use clean laminar flow booths?
    Clean laminar flow booths are widely used across many industries, including electronic component assembly and inspection, pharmaceutical and laboratory sterile operations, PCB and SMT production lines, precision instrument and optical product assembly, as well as filling and inspection areas in the food and cosmetics industries.
    Q What is the difference between HEPA and ULPA filters?
    HEPA filters achieve a filtration efficiency of ≥ 99.97% for particles ≥ 0.3μm, making them suitable for most cleanroom applications. ULPA filters offer a higher efficiency of ≥ 99.999% for particles as small as 0.1–0.2μm, and are used in ultra-high standard environments such as semiconductor manufacturing and bio-safety laboratories.
    Q What is an FFU and why is it important in a clean booth?
    An FFU (Fan Filter Unit) is the most critical component of a clean booth. It is a modular unit that integrates both a fan and a HEPA filter. Installed on the ceiling grille of the booth, the FFU draws in air, filters out contaminants, and pushes clean air downward into the workspace — forming the foundation of the clean environment.
    Q What are the main differences between vertical and horizontal laminar flow?
    Vertical laminar flow has FFU installed on the top of the booth, pushing clean air straight down like a piston to sweep contaminants away — this is the most common configuration. Horizontal laminar flow has FFU installed on the side wall, directing air horizontally across the work surface. Horizontal flow is used in specific processes where a top-down airflow pattern is not suitable.
    Q Why is aluminum profile the preferred frame material for clean booths?
    Industrial aluminum profiles (such as 4040 or 4080 series) are the preferred choice because they are lightweight yet strong, corrosion-resistant, and aesthetically appealing. Their anodized surface finish makes them easy to clean and maintain. Additionally, the modular nature of aluminum profiles allows flexible configuration into various booth sizes and shapes, offering excellent scalability.
    Q How are clean booth enclosure panels sealed to maintain cleanliness?
    Enclosure panels are connected using specialized tongue-and-groove joints, and sealant is applied strictly at all seams. This ensures the booth remains fully airtight, effectively preventing external contaminants from entering the clean workspace and maintaining the required cleanliness level inside.
