In 2026, a Duct Mounted HEPA Box (or HEPA Filter Housing) is the primary containment vessel for high-efficiency air filtration within an ACMV system. Under the Energy Efficiency and Conservation Act (EECA) 2024 and the latest DOSH ICOP IAQ 2026 standards, these boxes are no longer simple sheet-metal enclosures; they are precision-engineered mechanical modules designed to ensure "Zero-Bypass" performance. For facilities in Kuala Lumpur and Selangor, a poorly fabricated HEPA box leads to air leakage and excessive static pressure, which spikes your building's energy consumption and degrades your 5-Star BEI.
At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to the fabrication and installation of duct-mounted HEPA boxes. We ensure your filtration stage is airtight, compliant with MS 1472, and optimized for a 5-Star Energy Intensity Label.
The duct-mounted box serves as the structural anchor for the HEPA filter. If the box flexes or leaks, the filtration efficiency of the H13/H14 media is negated.
Knife-Edge & Gel-Seal Architecture: For 2026 high-stakes environments (ISO Class 5/6), we utilize Gel-Seal boxes. The housing features a precision-machined "Knife-Edge" that sinks into a silicone gel channel on the filter frame, creating a leak-proof, self-healing interface that outperforms traditional mechanical gaskets.
Fully Welded Liquid-Tight Construction: We utilize fully TIG-welded Stainless Steel 304/316 or powder-coated heavy-gauge galvanized steel. This ensures the box remains airtight under high static pressures (up to 1,000 Pa) and prevents corrosive moisture buildup, satisfying the highest DOSH indoor air quality standards.
Lowering the BEI: Every gap in a filter box creates a pressure leak that forces your Air Handling Unit (AHU) to over-work. By eliminating "Bypass Air," our boxes allow your Variable Frequency Drives (VFDs) to operate at the lowest possible hertz. This directly improves your Building Energy Index (BEI) and avoids peak power charges.
To meet BOMBA 2026 and SIRIM benchmarks, our HEPA boxes incorporate several critical mechanical features:
Every EKG HEPA box includes integrated Upstream Injection and Sampling Ports. This allows for mandatory ISO 14644-3 filter integrity testing (DOP/PAO) to be performed without breaching the duct’s pressure seal. This provides a transparent audit trail for NPRA or Ministry of Health inspectors.
To prevent energy-wasting turbulence, our boxes are engineered with precision Expansion and Contraction Plenums. This ensures that air velocity is uniform (laminar) across the entire filter face, maximizing the filter's lifespan and reducing your annual maintenance costs.
To satisfy BOMBA safety requirements, our boxes include Fire-Rated Access Panels with high-temperature, airtight gaskets. For boxes integrated into isolation rooms or BSL labs, we provide pressure-monitored interlocks that ensure the box remains sealed during sensitive operations.
Meeting Annual IAQ Audits: For Grade-A offices and healthcare facilities in KL and Selangor, DOSH audits require proof of filtration integrity. Our boxes provide the technical evidence and physical labeling required for smooth compliance.
Lowering TNB Maximum Demand: By eliminating air bypass and optimizing internal flow dynamics, we ensure your supply fans operate at their peak efficiency point. This secures your 5-star efficiency rating and lowers monthly operational costs.
Bio-Security & IAQ Tracking: Our boxes act as a sterile anchor, preventing the growth of tropical mold in the "dead zones" of your ductwork. This maintains a sterile environment, critical for both food safety and high-tech manufacturing.
34 Years of Engineering Depth: Based in KL, we are mechanical contractors who understand the forensics of terminal pressure. We don't just "install" boxes; we engineer the sterile and aerodynamic integrity of your life-safety infrastructure.
Turnkey Safety & Quality: All HEPA boxes are fabricated and installed to MS 1472 standards, utilizing SIRIM-certified and BOMBA-approved components.
Digital Twin Ready: We provide full 3D as-built data and pressure-drop logs for every unit, which can be integrated into your building's 3D digital twin for real-time facility management.
Is your air filtration path a hidden source of energy waste, or is it a model of 5-star engineered safety? Contact EKG M&E Sdn Bhd today for specialized duct-mounted HEPA boxes and secure the future of your infrastructure.
