In 2026, ISO Class 5 Cleanroom Filtration (formerly Class 100) represents the standard for ultra-sterile environments in Malaysia’s high-tech manufacturing and pharmaceutical sectors. Under the Energy Efficiency and Conservation Act (EECA) 2024, which became strictly enforceable on January 1, 2025, ISO Class 5 facilities must balance absolute particulate control with rigorous "Specific Fan Power" targets. For facilities in Kuala Lumpur and Selangor, maintaining this classification requires a terminal filtration strategy that achieves a 5-Star BEI while guaranteeing fewer than 3,520 particles ($\ge 0.5 \mu m$) per cubic meter of air.
At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide turnkey ISO Class 5 solutions. We ensure your sterile zone is hermetic, compliant with MS 1472, and optimized for a 5-Star Energy Intensity Label.
Achieving ISO Class 5 requires a "Piston-Effect" airflow, where treated air moves in a unidirectional, downward path to "flush" contaminants toward floor-level returns.
Terminal H14 HEPA/U15 ULPA Filtration: We utilize H14 HEPA (99.995% efficiency) or U15 ULPA (99.9995% efficiency) filters at the terminal ceiling point. For 2026 standards, we prioritize PTFE Membrane Media, which offers a 30%–40% lower pressure drop than traditional fiberglass, directly lowering your building's energy intensity.
Air Change Rates (ACR): ISO Class 5 typically demands between 240 to 480 air changes per hour. We utilize Variable Frequency Drives (VFDs) interlocked with real-time particle counters. By modulating the air changes based on actual occupancy and particulate load, we prevent energy waste, supporting your 5-Star BEI.
Laminar Velocity Control: To maintain a true laminar profile, we engineer the air exit velocity at 0.45 m/s ($\pm 20\%$). This prevents "Air Entrainment" (pulling contaminated air back into the clean stream), satisfying ISO 14644-1 benchmarks.
To meet NPRA, MOH, and BOMBA 2026 standards, our cleanroom integrations include specific mechanical safeguards:
In ultra-clean zones, mechanical gaskets are a liability. We utilize Gel-Seal (Knife-Edge) HEPA Modules. The filter frame is submerged into a specialized silicone gel channel, creating a self-healing, airtight barrier that eliminates "Filter Bypass"—the primary cause of cleanroom validation failure.
As of 2026, a "visual check" is insufficient for ISO accreditation. We perform mandatory ISO 14644-3 integrity testing using a Polyalphaolefin (PAO) aerosol challenge. Our modules feature integrated injection and sampling ports, allowing us to scan the filter face and seals for "pin-hole" leaks without breaching the sterile envelope.
We integrate digital Differential Pressure Sensors linked to your Building Management System (BMS). This ensures the ISO Class 5 zone remains at a constant positive pressure (typically $+15$ Pa to $+30$ Pa) relative to adjacent Class 7 or Class 8 gowning areas, preventing cross-contamination.
34 Years of Engineering Depth: Based in the Klang Valley, we understand the forensic maintenance required for Malaysia's specific psychrometric challenges. We don't just "install" filters; we engineer the sterile and aerodynamic integrity of your infrastructure.
Turnkey Life-Safety Integration: As M&E contractors, we coordinate your cleanroom filtration with BOMBA-certified Fire Dampers, gas interlocks, and smoke spill systems for a seamless safety handshake.
Digital Twin Capability: We provide full 3D as-built data and pressure-mapping logs for every terminal module, which can be integrated into your building's 3D digital twin for real-time facility management and maintenance.
Is your ISO Class 5 cleanroom a hidden energy drain or a model of 5-star engineered safety? Contact EKG M&E Sdn Bhd today for specialized cleanroom filtration solutions and secure the future of your infrastructure.
Are you looking to validate an existing cleanroom to comply with the 2025 Energy Efficiency Act, or are you specifying terminal filtration for a new high-tech manufacturing facility?
