1. Air supply ceiling ( laminar flow air supply ceiling ) Advantages
\nAir quality is excellent: vertical unidirectional laminar flow, without vortices or turbulence, capable of continuously suppressing floating dust and preventing cross-contamination, suitable for clean areas of Class 100\/ISO 5 and above standards.
\nUniform air outflow: large static pressure box + uniform flow structure, consistent air speed across the entire surface, stable temperature, humidity and cleanliness in the area.
\nStrong purification capacity: standard configuration of multiple-level filtration (primary \/ intermediate \/ high-efficiency \/ ULPA), capable of deeply trapping micro-particles, meeting strict requirements of GMP, medical, and semiconductor industries.
\nGood local control and purification effect: can form a local clean core area, allowing for a more relaxed requirement for the overall workshop’s cleanliness, and reducing overall operation and maintenance costs. Disadvantages
\nHigh cost: Complex structure, numerous components (static pressure box, multi-stage filters, equalizing components), procurement and installation costs are much higher than those of ordinary air vents.
\nHigh wind resistance and high energy consumption: The multi-stage filters and long air flow path result in high wind resistance, requiring a high static pressure fan to be matched. Long-term operation consumes more electricity.
\nComplex maintenance: Filters, seals, fans, and equalizing components need to be inspected, replaced, and leak-checked regularly, resulting in a large amount of maintenance work.
\nLarge space occupation: The static pressure box has a certain height, which requires higher ceiling height. The on-site installation space is limited.
\nLow wind speed: Only suitable for clean environment dust control, with slow air exchange and cooling speeds, not suitable for simple ventilation scenarios.
\nIII. Ordinary Air Ventilation Vents (Blades \/ Diffusers) Advantages
\nSimple structure, low cost: Few components, convenient for procurement, installation and construction, with high cost-effectiveness.
\nLow wind resistance, low energy consumption: Short air flow path, no complex filtering and rectification structures, low fan load, energy saving.
\nFast ventilation and heat exchange: High outflow wind speed, strong turbulent diffusion, high efficiency for space ventilation, temperature adjustment and dehumidification, suitable for conventional air conditioning ventilation.
\nSmall space occupation: Lightweight body, low requirements for ceiling and duct installation space, suitable for most buildings.
\nSimple maintenance: Generally only needs to clean the coarse filter regularly, no leak detection or complex maintenance requirements. Disadvantages
\nAir flow disorder: Predominantly turbulent flow, prone to generating vortices and dust accumulation, unable to control suspended particulate matter, not suitable for high-cleanliness areas.
\nWeak purification capacity: Most are equipped with only coarse filters, without high-efficiency filtration, unable to intercept sub-micron dust.
\nInconsistent air distribution: Without dedicated static pressure chambers, there are significant differences in local wind speed and pressure at the air outlets, resulting in dead zones in some areas.
