Kitchen Duct Degreasing: Exhaust Fan Grease Removal by EKG M&E Sdn Bhd

In 2026, Exhaust Fan Grease Removal is a critical mechanical maintenance task that directly impacts both building safety and energy overheads. Under the Energy Efficiency and Conservation Act (EECA) 2024 and BOMBA regulations, the rooftop or plant-room exhaust fan is the "engine" of your fire-safety system. For assets in Kuala Lumpur and Selangor, a grease-laden fan is a dual threat: it is a high-intensity fuel source for fires and a primary cause of "Energy Bleed" due to mechanical imbalance.

At EKG M&E Sdn Bhd, we apply 34 years of mechanical engineering expertise to provide specialized fan degreasing. We restore your fan to its original aerodynamic balance, supporting a 5-Star Energy Intensity Label and a 5-Star BEI.

1. The Engineering Logic: Restoring Aerodynamic Balance

A kitchen exhaust fan (typically a centrifugal or axial type) is a high-speed precision instrument. Grease buildup on the impeller blades disrupts the physics of airflow.

• Massive "Energy Drag": Uneven grease deposits on the fan blades act as "Parasitic Weight," forcing the motor to consume more electricity to maintain the same RPM. By removing this grease, 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 removal extends the life of these critical assets to 15+ years.

• Fire Safety at the Discharge: The fan housing is often the last point before air is discharged. If grease ignites here, the fire can spread to the rooftop membrane or adjacent cooling towers. Restoring the fan to Bare-Metal breaks this fuel chain.

2. Specialized Fan Degreasing Protocol

Our process is designed to protect the mechanical integrity of the motor while achieving a residue-free finish:

A. Impeller and Housing Restoration

We utilize food-safe, high-alkaline degreasers and high-pressure steam (80°C - 90°C) to strip grease from the impeller blades. We ensure that every blade is "Clean-to-Metal," restoring the factory-designed airflow curve.

B. Grease Drainage and Trap Remediation

Every exhaust fan should have a dedicated grease drain and collection container. We clear the drain lines and remediate the Grease Traps at the fan base to prevent liquid grease from leaking onto the rooftop, which can cause structural decay of the roof membrane.

C. Belt and Pulley Inspection

During the degreasing process, we inspect the fan belts and pulleys. Grease-slicked belts slip, losing up to 10% of their mechanical efficiency. We clean the pulleys and verify belt tension to ensure 100% power transmission from the motor to the fan.

4. Why Fan Degreasing is Essential for 2026

• 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 commercial infrastructure.

• Annual Fire Certificate (FC) Security: BOMBA inspectors specifically check the "Base of the Fan" for grease leaks. We provide the certified service logs and photos that prove your fan is a safe, maintained asset under MS 1472.

• Bio-Security & Odor Control (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.
