The ceiling air\u2011supply unit adopts an integrated cabinet structure. Its core components consist of six parts: pressure\u2011stabilizing plenum, HEPA filter module, flow\u2011equalizing air\u2011supply module, sealing system, inspection & test ports, and hoisting & fixing structure. The pressure\u2011stabilizing plenum is the main load\u2011bearing body, integrally formed from steel plate with outstanding air\u2011tightness. It buffers high\u2011pressure airflow coming from air ducts and stabilizes internal air pressure, preventing uneven air supply and eddy currents triggered by pressure fluctuation, so as to lay a pressure foundation for uniform air delivery. As the core purification component, the HEPA filter module is compatible with both gel\u2011seal and paper\u2011separated HEPA filters. H13 \/ H14 high\u2011efficiency filtration captures fine dust, bacteria and contaminants to ensure cleanliness of supply air.<\/p>\n

The flow\u2011equalizing air\u2011supply module, composed of high\u2011precision honeycomb flow equalizer and protective grille, is critical for achieving uniform airflow. After pressure stabilization and filtration, clean air undergoes secondary splitting and homogenization via the honeycomb flow equalizer. Turbulent high\u2011pressure airflow is converted into low\u2011speed, steady, vertical laminar flow, which evenly covers the working zone of workshops. It thoroughly solves common drawbacks of traditional air supply, such as excessive local wind speed, supply\u2011air dead corners and airflow turbulence. The sealing system adopts double\u2011layer sealing design. All gaps at cabinet joints and equipment mounting positions are fully sealed to eliminate risks of air leakage and contamination. Inspection and test ports support on\u2011site PAO leak testing and equipment service; maintenance and inspection can be completed without unit disassembly.<\/p>\n

Its core air\u2011supply principle follows four sequential stages: pressure stabilization, filtration, flow equalization and air delivery, forming a closed\u2011loop clean air\u2011supply system.<\/p>\n

    \n
  1. Pressure Regulation<\/strong>: High\u2011pressure duct airflow enters the pressure\u2011stabilizing plenum. The enclosed chamber buffers and stabilizes air pressure and flow velocity.<\/li>\n
  2. High\u2011efficiency Filtration<\/strong>: Air passes through high\u2011performance HEPA filters for comprehensive removal of fine particles and microorganisms to purify the airflow.<\/li>\n
  3. Flow Homogenization<\/strong>: Clean air is evenly distributed by honeycomb flow equalizer to unify airflow direction and wind speed.<\/li>\n
  4. Laminar Air Delivery<\/strong>: Uniform vertical laminar flow covers the workshop, carrying away dust and pollutants in working areas and sustaining clean indoor conditions. The whole process features stable airflow without turbulence or dead zones, perfectly meeting requirements for high\u2011grade clean environments.<\/li>\n<\/ol>\n

    For cleanliness\u2011grade compatibility, ceiling air\u2011supply units adapt to diverse scenarios according to different configurations:<\/p>\n

      \n
    • Equipped with H14 gel\u2011seal HEPA filters: applicable for Class\u202f100 \/ Class\u202f10 ultra\u2011high\u2011grade cleanrooms, for semiconductor, precision chip and aseptic vaccine manufacturing.<\/li>\n
    • Equipped with H13 gel\u2011seal HEPA filters: applicable for Class\u202f1000 cleanrooms, widely used for medical devices and biological laboratories.<\/li>\n
    • Equipped with H13 paper\u2011separated HEPA filters: applicable for Class\u202f10\u202f000 cleanrooms, for cosmetics, general pharmaceutical and precision\u2011electronics production.<\/li>\n<\/ul>\n

      Normal operating wind speed ranges from 0.3\u20110.5\u202fm\/s with uniformity error \u2264\u202f10\u202f%, fully complying with clean\u2011room airflow design standards.<\/p>\n

      In summary, with integrated structural design and multi\u2011layer airflow\u2011optimization technology, ceiling air\u2011supply units realize standardized, uniform and stable clean air supply, overcoming performance deficiencies of traditional air\u2011supply equipment. They are indispensable core air\u2011purification & air\u2011supply devices for high\u2011grade cleanrooms.<\/p>","protected":false},"excerpt":{"rendered":"

      Ceiling air\u2011supply units are integrated terminal air\u2011supply & purification devices dedicated to high\u2011grade cleanrooms. They integrate pressure stabilization, filtration, flow equalization, air supply and sealing into one unit. Mainly deployed in Class\u202f100, Class\u202f1000 and Class\u202f10\u202f000 clean workshops, they serve as core equipment to guarantee uniform airflow, stable environment and dust\u2011free & aseptic conditions.
