Duct Airtightness Test

Duct Airtightness Test by EKG M&E Sdn Bhd

In 2026, a Duct Airtightness Test is a critical engineering verification used to quantify the amount of air escaping from an HVAC system. Under the Energy Efficiency and Conservation Act (EECA) 2024, this test is the primary method for identifying "Energy Leaks" that inflate your Building Energy Index (BEI). For facilities in Kuala Lumpur and Selangor, airtightness is now a legal benchmark for securing a 5-Star Energy Intensity Label.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical expertise to conduct these tests, ensuring your "Injection Path" is hermetically sealed to optimize both air quality and power consumption.

1. The Engineering Objective

The goal of the test is to prove that the ductwork meets the DW143 Standard for its specific pressure class. Air leaking through joints, seams, or loose access panels creates two major problems:

• Fan Power Waste: Even a 10% leak can force your Variable Frequency Drives (VFDs) to work up to 30% harder to maintain the required static pressure.

• Infiltration Risks (DOSH 2026): Leaky ducts can pull contaminated air from ceiling voids into the conditioned air stream, making it impossible to stay below the legal bacterial ceiling of 500 cfu/m³.

2. The Airtightness Testing Protocol

We utilize a medical-grade, multi-stage process to verify the integrity of your air distribution network:

• Preparation & Isolation: We isolate a specific section of the ductwork using temporary high-pressure bladders. This ensures the test focus remains strictly on the duct joints and seams.

• Pressurization & Measurement: Using a calibrated tester (like a PANDA system), we pressurize the duct to its design operating pressure. The machine then measures the "Make-up Air" required to hold that pressure, which represents the Leakage Rate ($l/s/m^2$).

• Visual Leak Identification: If a system fails to meet its class (Class A, B, or C), we deploy Non-Toxic Smoke Generators. The escaping smoke visually pinpoints the exact failure points, allowing for surgical remediation.

• Verification & Certification: Once sealed, a final test is performed to generate the digital audit-trail required by your Registered Energy Manager (REM).

3. Compliance & Audit Documentation
