In the high-demand F&B corridors of 2026 Kuala Lumpur, an Upblast Roof Exhaust Fan is the industry standard for safe, grease-laden air extraction. Unlike standard fans that blow air downward—destroying roof membranes with flammable oils—upblast fans discharge exhaust vertically into the atmosphere. Under the Energy Efficiency and Conservation Act (EECA) 2024, which reached full enforcement on January 1, 2025, these high-capacity units are critical for maintaining a building's Energy Intensity Label. A fouled or imbalanced upblast fan is a major "Energy Leak" and a significant fire hazard under BOMBA and NFPA 96 regulations.
As a core specialization in our Exhaust Fan & AHU Overhaul suite, EKG M&E provides the precision balancing and grease-management restoration required to keep your kitchen compliant and your roof protected.
Upblast fans utilize centrifugal properties to move air while managing liquid effluent:
The "Roof-Protection" Geometry: By throwing air upward, these fans prevent grease from accumulating on your building's roof. In KL’s 35°C+ heat, rooftop grease becomes a "Fire Starter" and causes structural decay in the roofing membrane.
The "Cool-Motor" Vane: High-quality upblast fans feature a dedicated cooling vane that pulls fresh outside air over the motor, even while the main impeller is pulling 100°C+ air from the kitchen. This prevents the "Thermal Tripping" common during peak lunch rushes.
The Cube Law ($P \propto n^3$): Grease buildup on fan blades increases rotating mass. To maintain the same airflow ($L/s$), the motor must draw exponentially more power. A professional clean can reduce your fan’s energy consumption by up to 20%.
We treat every upblast service as a forensic fire-safety and mechanical event, adhering to NFPA 96, BOMBA, and MS1525:2024 standards:
Hinge Kit & Hold-Open Restoration: To comply with NFPA 96, we install and service heavy-duty Hinge Kits. This allows the fan to be tilted back safely for deep cleaning of the duct and blades without damaging electrical wiring or risking technician safety.
Grease Containment & Drain Audit: We verify the integrity of the localized grease drain and collection box. This ensures that "Grease-Mist" is captured and does not leak onto the roof, a major cause of failed fire inspections in 2026.
Non-Overloading Backward Inclined Wheel Deep Clean: We perform a Non-Sparking chemical degreasing of the impeller. This restores the "Backward Inclined" aerodynamic profile, ensuring the motor operates at its peak efficiency point on the fan curve.
3-Axis Laser Alignment & Tensioning: For belt-driven models, we use Laser Aligners and Sonic Tension Meters. This eliminates the "Squealing" and mechanical drag that increases your TNB Maximum Demand (MD) charges.
A certified EKG upblast service is a high-impact project for your building's financial and safety health:
Registered Energy Manager (REM) Validation: We provide the "Static Pressure and Power Audit" required for your building's mandatory 2026 energy audits.
BOMBA & DOE Compliance: Our services ensure your extraction system meets both fire safety and environmental guidelines, preventing the "Grease-Soot" pollution that leads to municipal fines.
VFD-Energy Integration: We can integrate your fan with a Variable Frequency Drive (VFD), allowing you to ramp down extraction during prep times, potentially saving up to 40% on monthly electricity bills.
