I. Project Overview

This project involves a high-efficiency modular cleanroom facility constructed for conductive slurry production processes, including powder unpacking, feeding, dust removal, and filling lines. Spanning a total area of over 500 square meters, the project represents a state-of-the-art implementation engineered for specialized petrochemical and advanced materials applications. As a premier cleanroom manufacturer and leading global cleanroom supplier, Wonclean Technology managed the design, pre-fabrication, and systematic integration to deliver a continuous, heavy-duty industrial controlled environment.

II. Design Standards & Parameters

The engineering parameters of this facility strictly adhere to international industrial codes and process-specific protocols:

• Cleanliness Level: ISO Class 8 criteria standard executed in strict accordance with ISO 14644 protocols.
• Airflow Pattern: Non-unidirectional flow (turbulent flow) design to ensure uniform air distribution.
• Air Changes: Minimum ventilation rate maintained at 15 air changes per hour (ACH) or greater to eliminate particulate accumulation.
• Pressure Gradient: Positive pressure threshold maintained at 10 Pa or higher relative to adjacent unconditioned zones, utilizing a stable differential pressure monitoring matrix.
• Environmental Conditions: The facility does not incorporate an independent temperature and humidity handling system; instead, it utilizes conditioned ambient air supplied from the primary manufacturing plant infrastructure without introducing any additional thermal or moisture loads.
• Acoustic Control: Environmental noise emission managed to remain at 60 dB(A) or lower measured at a distance of 1 meter outside the cleanroom perimeter.

III. Core System Configuration

The facility utilizes high-durability architectural partitioning and advanced air handling systems engineered for 24/7 continuous operation:

• Structural Enclosure: The internal partition walls are engineered using advanced cleanroom wall panel systems with rockwool and glass magnesium cores, providing excellent structural rigidity and fire protection. The overhead grid utilizes a heavy-duty cleanroom ceiling panel alignment, ensuring maximum airtightness and structural stability across the entire 500 square meters footprint.
• Air Handling & FFU Loop: Driven by a high-performance Fan Filter Unit (FFU) circulation loop mounted on the ceiling grid. The units are equipped with UL-certified fans and terminal HEPA filters (efficiency rating of MERV 17 or higher) operating continuously to ensure reliable contamination control.
• Air Distribution Network: Air supply ducts are fabricated from premium stainless steel, completely covered with rubber-plastic insulation and protective aluminum foil cladding to prevent condensation dripping. The return air loop incorporates side-wall lower return grilles equipped with volume control dampers (OBD).
• Logistics & Personnel Airlocks: Personnel entry is protected by a stainless steel double-person double-blow air shower. Material transfer points feature a heavy-duty stainless steel cargo air shower with double-sided PVC rapid roll-up doors, and a static electronic interlock pass box outfitted with UV germicidal lamps.

IV. Construction Highlights & Advantages

• Automated Production Line Integration: The cargo air shower units are engineered with dedicated I/O interfaces that link directly with automated material conveyor belts, allowing automated roll-up doors to interlock seamlessly with factory material flows.
• Airtight Mechanical Seal: All swing doors are equipped with automatic drop-down bottom seals and double-layer 5mm tempered glass vision panels flush-mounted to the wall surfaces, completely eliminating air leakage and dust-collecting dead angles.
• Zero-Thermal Perturbation: By sourcing pre-conditioned air from the main plant building and routing it through medium-efficiency pre-filtration before terminal HEPA delivery, the design avoids disturbing plant-wide climate control while fulfilling strict positive pressure parameters.
• Continuous Operational Integrity: Designed as a fully integrated, zero-maintenance structural loop that supports uninterrupted round-the-clock operations, ensuring maximum uptime for conductive slurry production lines.
