Key Installation Considerations for Air Distribution Ceilings (Filtration Hood \/ Clean Air Distribution Ceiling), On-site Construction + Acceptance Checklist
\nI. Foundation Lifting and Structure (Prevent Deformation, Prevent Top Fall, Prevent Air Leakage)
\nThe lifting load must be borne independently.
\nIt is strictly prohibited to rely on color steel plates or ceiling keels for support; independent channel steel \/ screw rod lifting frames must be made, and the load should be reserved according to the ceiling’s own weight + maintenance margin.
\nThe spacing of the screw rods should be uniform, and diagonal reinforcement should be done to prevent long-term sagging, deformation, and cracking of the joints and air leakage.
\nThe levelness must be strictly controlled.
\nThe overall horizontal error should be \u2264 \u00b12mm\/m; Inclination will cause: Air flow deviation, local accumulation of dust, condensation water, and uneven sealing resulting in air leakage.
\nTop static pressure box and air duct interface: Soft connections must be made to prevent the fan vibration from being transmitted to the ceiling, and long-term loosening of the seal and screws.
\nII. Sealing and Air Leakage Prevention (Installation Determines Later Cleanliness, Top Priority)
\nAll joint seams, flange openings, and maintenance openings: Use neutral anti-mold silicone sealant, continuous and full without breaks;False glue and broken glue are strictly prohibited.
\nInstallation of high-efficiency filters\uff1a
\nSealant strips should be flat without compression or offset\uff1b
\nThe pressure frame should be tightened evenly and in several steps diagonally. It is strictly prohibited to apply dead pressure on one side (directly damaging the filter material and causing air leakage from the frame).
\nBefore installation\uff0c clean the inner wall of the static pressure box\uff0c vacuum + wipe\uff0c leaving no floating dust.
\nCeiling and wall\uff0c color steel plate sealing\uff1a Install sealing strips + apply glue to prevent dust accumulation and dirty air infiltration.
\nIII. Air Duct and Air Pressure\/Air Volume Matching
\nThe air intake duct should not have sharp bends or reduced diameters\uff1b avoid vortex and unstable static pressure\uff0c resulting in fluctuating air output.
\nThe system static pressure should be calibrated in advance to ensure uniform static pressure inside the ceiling and prevent local wind speed from exceeding standards \/ areas without air flow.
\nThe inner wall of the air duct should be clean\uff0c the sealing is well protected\uff0c and no debris\uff0c welding slag\uff0c or dust should fall into the static pressure box throughout the installation process.
\nIV. Installation Specifications for Filters \/ Diffusion Membranes
\nHigh-efficiency filters arrived on site should be inspected first\uff1a no damage to appearance\uff0c no cracking of the glue\uff0c and if necessary\uff0c re-inspected for leaks before entry.
\nThe entire installation process should be dust-free\uff1a personnel should wear clean suits and must not touch the filter material\uff0c poke the membrane\uff0c or press the filter surface with their hands.
\nDiffusion layer \/ diffuser plate\uff0c PTFE diffusion membrane\uff1a Flat\uff0c without wrinkles\uff0c without pulling\uff0c complete fixing clips to prevent bulging\uff0c air leakage\uff0c and chaotic air flow.
\nV. Electrical\uff0c Pressure Difference\uff0c and Instrument Installation
\nStandard position for pressure difference measurement points\uff1a one side measures the static pressure box\uff0c the other side measures the air outlet side\uff0c and the wiring should be concealed and waterproof.
\nSensors and pressure difference meters should be firmly fixed\uff0c shockproof\uff0c and free from loosening to avoid later reading drift and false pressure difference.
\nThe wiring of the fan \/ FFU should be standardized\uff0c with reliable grounding\uff0c and reserved power-off marking points for maintenance.
\nVI. Cleanliness Protection and Construction Control
\nDuring installation\uff1a The air outlet should be fully covered with film to prevent dust\uff0c paint\uff0c and welding smoke from entering the box.
\nCross-construction must not step on the ceiling or stack materials above the ceiling\uff1b do not cut or sand below while generating dust.
\nReserve reasonable interfaces for sterilization and disinfection liquid to avoid later leakage and damage to the seal and filter material.
\nVII. Must-do Acceptance (If Not Installed = White Installation)
\nOverall air tightness\uff0c visual and tactile inspection of joints\uff1b Leak detection for PAO high-efficiency filters\uff1b
\nUniformity of wind speed at multiple points (within the compliance range)\uff1b
\nInitial pressure difference should be archived and recorded (for the sole reference in later filter replacement)\uff1b
\nThe cleanliness and suspended particle count should be re-tested and qualified before commissioning.
\nVIII. Frequent Pitfalls to Remind
\nWithout installing the hanging brackets\uff0c relying on color steel plates for lifting \u2192 Later deformation and air leakage\uff1b
\nSingle-sided pressure tightening of the filter \u2192 Leak detection must be discarded\uff0c long-term particle loss\uff1b
\nInstallation without sealing \u2192 New filter blocks quickly become clogged\uff1b
\nNo archiving of the initial pressure difference \u2192 Later not knowing whether to replace the filter.<\/p>","protected":false},"excerpt":{"rendered":"
