In 2026, ULPA (Ultra-Low Penetration Air) filter servicing in Malaysia is governed by a strict intersection of ISO 14644-2:2015 (Monitoring) and the Energy Efficiency and Conservation Act (EECA) 2024, which came into full effect on January 1, 2025.
At EKG M&E, we utilize 34 years of engineering depth to provide Condition-Based Servicing that ensures 99.9999% purity while meeting Malaysia's new 2026 green energy benchmarks.
Under the 2026 regulatory framework, the frequency of your ULPA service is determined by your Cleanroom Class and your Risk Assessment Plan:
ISO Class 1 to 5 (Critical): Requires a full integrity and performance audit every 6 months.
ISO Class 6 and Above: Requires service every 12 months.
EECA Compliance Audit: Large energy consumers must now include their cleanroom HVAC performance in their Annual Energy Efficiency Report to the Energy Commission.
A professional ULPA service by EKG M&E involves four critical engineering steps:
Unlike HEPA, we do not use standard photometers for U16/U17 filters. We use High-Sensitivity Laser Particle Counters to detect individual 0.1-micron particles.
The Scan: We perform a 100% "overlapping stroke" scan of the media and the Gel-Seal interface.
Leak Limit: Any localized penetration exceeding 0.001% (for U15) or 0.0001% (for U17) triggers an immediate service remediation.
Under the EECA 2026, "Over-ventilation" is now a compliance penalty.
Velocity Dial-In: We use the Variable Frequency Drive (VFD) to lock the airflow at precisely 0.45 meters per second (the global laminar standard).
The Cube Law Advantage: If your fans are running at 100% but only need 80% speed to maintain Class 10 purity, we recalibrate the VFD. Following the Cube Law, this 20% speed reduction cuts your electricity bill by nearly 50%.
ULPA filters are prone to "media shedding" if the system vibrates.
Resonance Check: We perform Fast Fourier Transform (FFT) analysis on the filter housing.
Harmonic Skipping: If the AHU fan motor creates a harmonic vibration at a certain RPM, we program the VFD to "skip" that frequency, preventing microscopic cracks in the U17 media.
We calibrate the Differential Pressure (Delta P) transmitters. In 2026, these sensors must be accurate within +/- 1 Pascal to feed reliable data into your building’s automated Energy Management System (EnMS).
With the RM150 million Energy Transition Fund introduced in the 2026 Malaysian Budget, many facilities are moving toward Smart Cooling.
Predictive Replacement: We don't replace ULPA filters on a calendar basis. We replace them when the Energy Penalty of the clogged filter (high pressure drop) exceeds the cost of a new filter.
The Tipping Point: For most U15 systems, this occurs when the pressure drop reaches 500 to 600 Pascal.
34 Years of Engineering Depth: We are Malaysia’s specialists in high-stakes semiconductor and pharmaceutical MEP.
Audit-Ready Documentation: We provide the ISO 14644 Compliance Certificates and VFD-Energy ROI data required for DOSH and Energy Commission audits.
Advanced Tooling: We use only NATA/SAMM-calibrated instrumentation for all particle and velocity measurements.
