The purification performance, operational stability and acceptance pass rate of a clean booth are fully determined by on-site installation craftsmanship, sealing treatment and commissioning precision. As a modular assembled unit, clean booths<\/a> seem simple to install, yet they demand extremely high standards for detailed workmanship. Most later defects such as air leakage, dust infiltration, uneven cleanliness, unstable air velocity and dust accumulation inside the booth arise from non-standard installation, poor sealing and inaccurate commissioning. Especially for GMP projects and high-end precision manufacturing projects, strict acceptance criteria apply to installation accuracy, measured data and sealing performance of clean booths. Any minor oversight may lead to failed project acceptance. Drawing on years of field implementation experience, Bacclean has compiled standardized operating procedures for clean booths, covering site preparation, assembly installation, power-on commissioning, on-site measurement and final acceptance, providing actionable implementation references for construction work, equipment commissioning and project acceptance.<\/p>\n

\"\"<\/p>\n

1. Pre-installation Site Verification (Core Preparatory Step)<\/p>\n

Comprehensive site inspection must be completed before equipment delivery to avoid potential installation risks.<\/p>\n

    \n
  1. \n

    Site inspection: Confirm the installation floor is flat, solid and free of bumps or depressions. Verify workshop floor height meets the booth installation requirement, with sufficient operation and maintenance space reserved around. For inline clean booths, double-check the length, width of the production line and operation route to ensure precise dimension matching.<\/p>\n<\/li>\n

  2. \n

    Power supply inspection: Independent dedicated power circuit for the equipment. Voltage and power rating shall match equipment parameters, fitted with separate air switch and earthing device. Anti-static and explosion-proof units require separate compliance verification for earthing.<\/p>\n<\/li>\n

  3. \n

    Environment inspection: Main workshop finishing and dust cleaning shall be mostly finished, with no large amount of construction dust, to prevent filter element premature clogging caused by dust contamination during booth assembly and commissioning.<\/p>\n<\/li>\n

  4. \n

    Component inspection: Count frame profiles, FFU fan units, enclosure panels, sealing accessories and electric control assemblies. Verify model and quantity to ensure no missing or damaged parts.<\/p>\n<\/li>\n<\/ol>\n

    2. Modular Assembly Specifications<\/p>\n

    Clean booths adopt standardized modular assembly for efficient installation, consisting of five core steps. Strict workmanship control guarantees stable structure and reliable sealing.<\/p>\n

      \n
    1. \n

      Frame assembly: Assemble bottom and top aluminum frames per drawing dimensions, fasten all connecting screws, calibrate frame levelness and verticality to ensure the whole structure is square, free of tilt and wobble, with tightly fitted joints without gaps.<\/p>\n<\/li>\n

    2. \n

      Column mounting: Fix surrounding columns to reinforce the overall frame structure, ensuring sufficient load-bearing capacity and no deformation during long-term operation.<\/p>\n<\/li>\n

    3. \n

      Ceiling installation: Lay top dust-proof tarpaulin or panels flat without wrinkles or looseness. Seal all ceiling joints thoroughly to block dust penetration from the top.<\/p>\n<\/li>\n

    4. \n

      Enclosure installation: Mount PVC soft curtains or hard panels according to design requirements. Soft curtains shall be precisely cut and hang neatly, with overlapping joints leaving no gaps.<\/p>\n<\/li>\n

    5. \n

      FFU installation: Embed FFU fan filter units accurately into the top frame, fix neatly in alignment. Ensure tight sealing between fans and ceiling frame to eliminate air leakage at fan joints.<\/p>\n<\/li>\n<\/ol>\n

      3. Precision Sealing Treatment (Key to Acceptance)<\/p>\n

      \"\"<\/p>\n

      Sealing performance directly determines the positive pressure environment and cleanliness stability inside the clean booth, which is the most critical and error-prone installation step. All frame joints, ceiling panel gaps, FFU mounting seams and enclosure joints shall be double-sealed with dedicated sealing strips and sealant to fully block air leakage risks. Soft curtains shall maintain proper hanging length at the bottom for convenient personnel and material passage while effectively isolating external dust. Corners, edges and column connection points require reinforced sealing to eliminate hidden dust infiltration gaps. After full assembly, visual inspection of all sealing positions shall be performed to ensure no missing seals, gaps or loose parts, enabling stable slight positive pressure inside the booth.<\/p>\n

      4. Full-process Power-on Commissioning<\/p>\n

      After installation, perform step-by-step standardized power-on commissioning to verify all functions and performance parameters.<\/p>\n

        \n
      1. \n

        Pre-power no-load check: Confirm all wiring is correct, fans free of stuck foreign objects, filter elements properly installed, frame stable and sealing intact. Power-on is permitted only after safety risks are ruled out.<\/p>\n<\/li>\n

      2. \n

        Fan operation commissioning: Turn on FFU units one by one, check operation status for abnormal noise, vibration or uneven rotation speed. Verify correct fan rotation direction and smooth air supply.<\/p>\n<\/li>\n

      3. \n

        Air velocity uniformity commissioning: Use professional anemometer to conduct multi-point air velocity measurement at different heights and zones within the booth. Calibrate fan speed to achieve stable and uniform air velocity across the whole area, eliminating low-air-speed or dead zones and maintaining regular laminar airflow.<\/p>\n<\/li>\n

      4. \n

        Electric control commissioning: Test equipment start\/stop, overload protection, delayed operation, fault alarm and other functions. For high-end models, debug monitoring, data storage, bilingual operation and other customized functions to ensure full functionality.<\/p>\n<\/li>\n

      5. \n

        Anti-static commissioning: Measure anti-static parameters across the booth with professional instruments and verify earthing system validity to meet anti-static requirements.<\/p>\n<\/li>\n<\/ol>\n

        5. On-site Measurement & Final Acceptance Standards<\/p>\n

        After commissioning, standardized on-site acceptance tests shall be carried out with measured data as acceptance basis. Four core acceptance items are required:<\/p>\n

          \n
        1. \n

          Cleanliness test: Measure particle concentration inside the booth according to project class requirements. Class 100, Class 1000 and Class 10,000 cleanliness levels must be fully compliant with no out-of-spec points.<\/p>\n<\/li>\n

        2. \n

          Air velocity uniformity test: Stable and uniform air velocity across the whole booth without obvious deviation and stable laminar airflow.<\/p>\n<\/li>\n

        3. \n

          Sealing performance test: Maintain stable slight positive pressure inside the booth with no air leakage or dust infiltration. The clean environment can be sustained after closing access openings.<\/p>\n<\/li>\n

        4. \n

          Function & safety test: Stable fan operation, normal electric control functions, qualified anti-static \/ explosion-proof performance and solid structure without wobble. All test data shall be recorded and filed to form a complete final acceptance report, serving as core documentation for project acceptance and equipment handover.<\/p>\n<\/li>\n<\/ol>\n

          \"\"<\/p>\n

          6. Common Installation & Commissioning Faults and Quick Solutions<\/p>\n

            \n
          1. \n

            Substandard cleanliness: Prioritize gap air leakage and insufficient sealing. Secondly check insufficient FFU fan speed or clogged filter media.<\/p>\n<\/li>\n

          2. \n

            Uneven local air velocity: Abnormal fan speed in corresponding zones, offset fan installation or air outlet obstruction. Re-calibrate and re-commission.<\/p>\n<\/li>\n

          3. \n

            Dust infiltration at soft curtain joints: Insufficient overlapping of soft curtains or inadequate hanging length at bottom. Adjust length and reinforce sealing.<\/p>\n<\/li>\n

          4. \n

            Abnormal fan noise & vibration: Loose fan fixing, dust accumulation on impeller or uneven mounting. Fasten, calibrate and perform maintenance cleaning.<\/p>\n<\/li>\n

          5. \n

            Unqualified anti-static parameters: Loose earthing wire or non-anti-static components. Replace parts and re-establish earthing connection.<\/p>\n<\/li>\n<\/ol>\n
