DOSH ICOP IAQ 2026 AHU Audits: Particulate Matter (PM2.5 / PM10) IAQ Validation

In the highly dense commercial centers of Kuala Lumpur and Selangor, atmospheric pollution is an ongoing threat to the indoor environment. Ambient vehicle emissions, industrial exhaust, and seasonal haze continuously press against your building’s envelope.

When your primary Air Handling Units (AHUs) draw in outdoor air, they don't just pull in oxygen—they pull in microscopic pollutants categorized as Particulate Matter (PM2.5 and PM10).

• PM10 (Coarse Particulates): Microscopic dust, pollen, and mold fragments ($\le 10 \ \mu\text{m}$). These get trapped in the upper respiratory tract.

• PM2.5 (Fine Particulates): Combustion particles, organic compounds, and metals ($\le 2.5 \ \mu\text{m}$). These are small enough to penetrate deep into the lungs and enter the bloodstream, triggering severe long-term health risks.

Under the strict mandates of the DOSH ICOP IAQ 2026, failing to validate and maintain indoor PM2.5 levels below $35 \ \mu\text{g/m}^3$ is a direct occupational safety violation.

As a specialized mechanical installation contractor—focusing strictly on precision site execution, not fabrication—EKG (Malaysia) SDN BHD provides forensic Particulate Matter IAQ Validation Services paired with the precise mechanical upgrades required to seal your borders against airborne dust.

The Particulate Diagnostic Protocol

To secure your legal compliance and protect your tenants, we replace visual inspections of filters with strict aerodynamic and laser-counting telemetry.

1. Continuous Laser Particle Counting

We map the physical dust load. Our technicians deploy calibrated, high-accuracy laser particle counters across your occupied office floors and directly inside the supply air plenums. Over an extended operational logging cycle, we measure the exact mass concentration of particles in micrograms per cubic meter ($\mu\text{g/m}^3$). This data reveals exactly when and where particulate spikes occur during peak working hours.

2. Filter Integrity & Bypass Auditing

Filters are useless if air can sneak around them. We conduct physical inspections of your primary pre-filters and secondary bag filter tracks. We hunt for crushed frames, structural sagging, and degraded perimeter gaskets. If raw, unfiltered outdoor air is bypassing the filter media through gaps in the framing assembly, your indoor particulate counts will inevitably fail DOSH standards.

3. Differential Pressure ($\Delta P$) Calibration

We check the breathing resistance. Using digital manometers, we measure the precise pressure drop across your filter banks.

• Low $\Delta P$ can flag a torn filter or severe air bypass.

• High $\Delta P$ indicates heavily choked, saturated media that is choking your airflow and forcing your fan motors to overwork.

The EKG Execution Standard

When our validation logs flag non-compliant particulate levels, we don't just hand you a data report. EKG delivers the high-spec mechanical execution required to restore absolute air containment.

Upgrading the Filtration Barrier (EECA 2024 Alignment)

We physically service, realign, and rebuild damaged filter holding frames to eliminate air bypass entirely. We ensure your system is fitted with high-integrity, low-resistance media precisely matched to your AHU's design static pressure.

By eliminating dirt accumulation on your cooling coils and upgrading to aerodynamically optimized filters, we drastically reduce internal static pressure loops. This allows your VFD-driven fan motors to push clean air at lower frequencies, reducing your Specific Fan Power (SFP) and trimming your monthly TNB utility bill in full compliance with the Energy Efficiency and Conservation Act 2024.

Eliminating "The Sponge Effect" (DOSH IAQ 2026)

Particulate accumulation is heavily aggravated by internal moisture. When microscopic dust particles slip past old filters, they land on the internal casing surfaces. If your AHU relies on old internal fiberglass insulation, this dust gets trapped inside the damp fibers like a giant sponge, creating a nutrient-rich soil that accelerates toxic mold and fungal blooms.

The EKG Standard: We execute complete extraction. Our teams strip out degraded fiberglass linings down to bare metal and install smooth, Fiber-Free Closed-Cell Insulation. This establishes a permanent, hydrophobic internal skin. Particulates cannot embed into the material, and water rolls straight into the drain tracks, making biological cultivation impossible and securing your compliance under the strict 500 $\text{CFU/m}^3$ DOSH fungal limit.

The Hardwired BOMBA Override

Your filtration and ventilation upgrades must never compromise building safety. During our mechanical interventions, we manually verify the physical safety interlocks connected directly to the local Fire Alarm Monitoring System. We guarantee that if an emergency trigger occurs, all automated IAQ software loops and VFD speed parameters are instantly bypassed to force the system into immediate smoke-spill ventilation or complete containment shutdown.
