In 2026, Rooftop Upblast Fan Grease Scraping is a critical mechanical maintenance task that directly impacts the life-safety and energy performance of your infrastructure. Under the Energy Efficiency and Conservation Act (EECA) 2024 and BOMBA regulations, the upblast fan is the "engine" of your extraction system. For assets in Kuala Lumpur and Selangor, a grease-laden fan impeller is a primary cause of "Energy Bleed" due to mechanical imbalance and a significant fire risk to the roof membrane.
At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide specialized fan restoration. We ensure your fan is returned to its original aerodynamic balance, supporting a 5-Star Energy Intensity Label and a 5-Star BEI.
A rooftop upblast fan is a high-speed precision instrument. Grease buildup on the impeller blades disrupts the physics of airflow.
Eradicating "Parasitic Drag": Uneven grease deposits on the fan blades act as "Parasitic Weight," forcing the motor to consume more electricity to maintain the required RPM. By scraping these blades to Bare-Metal, we allow your Variable Frequency Drives (VFDs) to operate at lower frequencies, directly lowering your Building Energy Index (BEI).
Vibration and Bearing Protection: Asymmetric grease accumulation causes mechanical vibration. This vibration leads to premature failure of bearings, seals, and motors. Professional scraping extends the life of these critical assets and prevents "Energy Bleed" from an over-worked motor.
Rooftop Membrane Protection: Grease that isn't removed from the fan housing can leak onto the rooftop. Because grease is acidic, it can cause structural decay of the roof membrane, leading to costly leaks and structural repairs.
Our process is designed to protect the mechanical integrity of the motor while achieving a residue-free finish:
We utilize specialized non-sparking scrapers to remove "Carbonized Cake"—the hard, baked-on grease that accumulates on the impeller blades and the internal housing. We ensure that every blade is "Clean-to-Metal," restoring the factory-designed airflow curve.
Following the scraping, we apply industrial-grade, Food-Safe Alkaline Degreasers and high-pressure steam (80°C - 90°C). This chemical wash removes the remaining molecular grease film, ensuring the surface is 100% free of flammable residue.
Every upblast fan must have a dedicated grease drain and collection container. We clear these drain lines to ensure liquid grease is correctly channeled, preventing it from pooling in the fan base or leaking onto the roof, satisfying DOSH 2026 bio-security standards.
| Performance Metric | Standard "Wipe-Down" | EKG Professional Scraping |
| Blade Cleanliness | Partial / Surface | 100% Bare-Metal Restoration |
| Mechanical Balance | Often Ignored | Verified Aerodynamic Stability |
| Vibration Levels | High (Energy Waste) | Minimal (Optimized for 2026) |
| Verification | None | Digital Photo/Maintenance Logs |
| EECA 2024 Status | Regulatory Risk | Audit-Ready for 5-Star BEI |
Annual Fire Certificate (FC) Security: BOMBA inspectors specifically check the "Base of the Fan" for grease leaks. We provide the certified service logs and timestamped digital photos that prove your fan is a safe, maintained asset under MS 1472.
Lowering TNB Maximum Demand: By restoring the fan's efficiency, we reduce the total amperage required for operation. This flattens your energy profile and avoids the peak power charges that penalize inefficient infrastructure in Malaysia.
Bio-Security & IAQ (DOSH 2026): Grease at the discharge point is a major source of odors that can be sucked back into the building’s fresh-air intakes. Our process ensures your facility stays below the legal 500 cfu/m³ bacterial ceiling.
34 Years of Engineering Depth: Based in KL, we are mechanical contractors who understand the forensics of HVAC systems. We don't just "clean"; we ensure your mechanical assets perform at peak safety.
Turnkey Safety Documentation: You receive a complete digital dossier, including "Before and After" photos, motor amperage readings, and a certified technician's sign-off.
Digital Twin Ready: We can integrate your fan maintenance history into your building's 3D digital twin, providing your facility managers with real-time visibility of your safety and energy compliance.
