System Overview A ventilate sandwich panel is a modular cleanroom return air panel engineered to organize airflow direction and support integrated fresh-air circulation without external ductwork. Positioned at the lower part of the workshop, it channels air in the same direction as particle settlement, ensuring dust and contaminants are carried directly to the return air outlet. Built as a modular sandwich structure and available in louver, grate-hole, mesh-plate, orifice-plate, and mushroom-outlet configurations, it integrates with fresh-air circulation and filtration systems to maintain consistent air quality across general cleanroom workshops. Key architectural advantages include: Unified Airflow Direction: Return air outlets are positioned in the lower zone of the workshop so airflow matches the natural settling direction of dust particles, maximizing removal efficiency. Integrated Air Channels: Air distribution pathways are built into the panel structure, eliminating external ductwork, saving overhead space, and reducing static electricity build-up. Cross-Contamination Prevention: High filter efficiency at the return air outlet supports fresh-air circulation and blocks pollutant migration between adjacent cleanroom workshops.

System Overview A soundproof panel is an acoustic-insulation panel engineered to control noise transmission in industrial and commercial settings. A micro-perforated metal facing sits over a high-density mineral wool or fiberglass core in a sealed, layered construction, allowing the panel to both absorb sound energy (NRC / α) and block its transmission (Rw / STC) in a single build. Available in customizable perforation patterns, thicknesses, and finishes, it dampens both airborne and impact noise while maintaining thermal and structural performance, integrating seamlessly with cleanroom wall and ceiling systems for laboratories, studios, and production areas. Key architectural advantages include: Dual Acoustic Function: The perforated face absorbs sound energy to reduce echo, while the dense, sealed core blocks transmission to the adjacent space. Tunable Core Performance: A non-combustible mineral wool or fiberglass core is matched to your target frequency, with Rw / NRC / STC ratings confirmed per configuration. Sealed, Flanking-Free Construction: An aluminum edge frame and airtight joints prevent leaks that would otherwise short-circuit acoustic performance.

System Overview A fiberglass panel (also known as glass fiber insulation board or FR-4) is an asbestos-free composite synthesized from glass fiber and high heat-resistance resin, offering high mechanical and dielectric strength alongside exceptional heat and moisture resistance and superior processability. Widely specified for plastic molds, machine manufacturing, and PCB fixtures, it also performs as a sound-absorbing wall and ceiling material, replacing ultra-fine glass wool felt in cold-storage rooms, broadcast studios, and ventilation trenches. Key architectural advantages include: Wide Temperature & Moisture Resistance: Stable from −30°C to +150°C with no deterioration or mildew, far outperforming traditional cork or wood board. Precision Surface & Processability: High flatness with no pits and standard thickness tolerances make it excellent for drilling, injection molds, and precision PCB fixtures. Effective Sound Absorption: A porous structure reflects and absorbs sound waves when built with rigid, tight walls, ideal for insulation and building acoustics applications.
