Qingdao cleanroom air filtration equipment configuration

Qingdao cleanroom air filtration equipment configuration

The core of configuring cleanroom air filtration equipment is based onISO cleanliness level, building a graded filtration system that takes into account purification efficiency, energy consumption, and operational convenience, ensuring that indoor pollutants such as particles and microorganisms are controlled within the standard range, adapting to the production needs of industries such as electronics, medicine, and food, and strictly following GB 50073, etc*Standard specifications.

The core of the configuration is a three-level filtering architecture, lacking/must not./Grade is primary filter（G4 level) mainly intercepts large particles of dust, hair, etc. with a diameter of ≥ 5 μ m. It is installed at the new and return air vents of the air conditioning unit, with low cost but no shortage. It needs to be replaced every 1-2 months to avoid damage to the backend equipment caused by large particles. The second level is a medium efficiency filter (F8 level) that intercepts fine particles ≥ 1 μ m and is installed in the air conditioning supply section. It is replaced every 3-6 months and its core function is to protect the end high-efficiency filter and extend its service life. The third level is a high-efficiency filter (H13/H14 level), with a filtration efficiency of ≥ 99.97 for particles ≥ 0.3 μ m/, installed at the end of the air supply,2-3 years of replacement is a key defense line for achieving cleanliness standards, and PAO leak detection is required after installation.

Equipment selection needs to match cleanliness level:ISO 6-8 ordinary clean room, using conventional three-stage filtration and non unidirectional airflow organization, with evenly distributed air supply ports and low-level return ports; ISO 1-5 high-precision areas require FFU fan filtration units, using unidirectional airflow to ensure no eddy currentsfourCorner. At the same time, it is necessary to configure a purification air conditioning unit and use a variable frequency fan to adjust the air volume, maintain positive indoor pressure, and reduce the pressure difference between clean and non clean areas≥10Pa， Prevent external pollution from infiltrating.

The supporting design and operation also need to be followed up synchronously. The air ducts are made of galvanized steel plates, with tight sealing and air leakage rate≤1/Regularly monitor the resistance of the filter to reach the initial resistanceReplace it promptly when it doubles. Reasonable configuration can not only meet the requirements of cleanliness, but also reduce energy consumption, avoid substandard cleanliness caused by equipment reduction or improper installation, and provide guarantee for the stable operation of the clean room.
