The Centrifugal Upblast Exhaust Fan is the industry standard for commercial kitchens, specifically engineered to discharge grease-laden air vertically away from the building's roof surface. EKG M & E Sdn Bhd specializes in the sizing, installation, and balancing of these high-performance units, ensuring that your extraction system meets both BOMBA fire safety requirements and DOE environmental guidelines.
Vertical Discharge Design
Unlike horizontal fans that blow grease onto the roof membrane (creating a fire hazard and causing structural decay), upblast fans throw exhaust high into the air. This protects your roof and reduces the buildup of flammable oils on the building's exterior.
Belt-Drive Motor Protection
We prioritize belt-driven models where the motor is isolated from the hot, grease-saturated airstream. This significantly extends the motor's lifespan and allows for easy speed adjustments by simply changing the pulley sizes.
Forced-Air Motor Cooling
Our fans feature a dedicated cooling vane that pulls fresh outside air over the motor, even while the main impeller is pulling $200^\circ\text$ air from the kitchen below. This prevents "thermal tripping" during peak cooking hours.
Standard Grease Drain & Hinge Kits
To comply with NFPA 96, we install every fan with a localized grease drain and a heavy-duty hinge kit. This allows the fan to be tilted back safely for deep cleaning of the duct and the fan blades without disconnecting the electrical wiring.
Non-Overloading Backward Inclined Wheels
The centrifugal impellers are designed to be "non-overloading," meaning the motor won't burn out even if the static pressure in the ductwork changes due to dirty filters or closed dampers.
Vibration Isolation & Curb Mounting
We mount fans on insulated roof curbs with spring or rubber isolators. This is critical in KL and PJ high-rises to ensure that mechanical "humming" does not disturb tenants on the floors directly below the roof.
Weatherproof Aluminum Construction
The housings are constructed from heavy-gauge, spun aluminum. This provides superior corrosion resistance against the tropical rain and high humidity common in the Klang Valley.
Precision Airflow Balancing
As an M&E firm, we don't just "install a fan." We use digital manometers to measure the Static Pressure ($P_s$) of your entire duct run, ensuring the fan is operating on its optimal "Fan Curve" for maximum efficiency.
Strategic Support in KL & PJ
We provide rapid response for fan failures in the busy commercial hubs of Kuala Lumpur and Petaling Jaya, offering on-site belt replacements, bearing overhauls, and motor rewinding.
Energy-Saving VFD Integration
We can integrate your upblast fan with a Variable Frequency Drive (VFD), allowing your kitchen staff to reduce extraction power during prep times, potentially saving up to 40% on monthly electricity bills.
