The leak-proof air supply ceiling is an upgraded and optimized version of the laminar air supply ceiling. The core difference lies in the decoupled design of the filtration and leak prevention mechanism, as well as the resulting advantages in installation, maintenance, airflow, and cost.
\n1. Core Principle and Structural Differences
\n1. Traditional laminar air supply ceiling (conventional \/ ordinary type)
\nStructure: The high-efficiency filter (HEPA) is directly installed at the end of the air supply (at the bottom), and below is the diffuser plate \/ mesh plate.
\nPrinciple: Air \u2192 Static pressure box \u2192 End high-efficiency filter \u2192 Diffuser plate \u2192 Inside the room.
\nLeak prevention logic: Relying on the absolute sealing of the end filter. Once the frame or filter core leaks, the contaminated air directly enters the clean area, without secondary protection.
\nAir flow coverage rate: Approximately \u2264 70%, prone to dead corners.
\n2. Leak-proof air supply ceiling (DSC)
\nStructure: Based on the leak-proof layer theory, the high-efficiency filter is moved to the upper part of the static pressure box (not at the end), and an additional sub-high-efficiency leak-proof layer (damping layer) is added at the end.
\nPrinciple: Air \u2192 Static pressure box \u2192 Pre-high-efficiency filter \u2192 Mixed and evenly distributed \u2192 End leak-proof layer \u2192 Inside the room.
\nLeak prevention logic:
\nThe pre-HEPA is responsible for the main filtration, using zero-pressure sealing technology.
\nThe end leak-proof layer (sub-high-efficiency) undertakes the triple functions of secondary filtration + uniform distribution + leak prevention.
\nEven if the pre-HEPA has a slight leakage, the leaked particles will be intercepted by the end leak-proof layer, reducing the contamination impact to 1\/475 of the traditional level.
\nAir flow coverage rate: \u2265 90%\u201395%, the airflow is more uniform and more resistant to interference.
