In the commercial and industrial landscapes of KL and Selangor, Rooftop Exhaust Fans are the critical final point of a building’s ventilation strategy. By mounting the fan on the roof, we save valuable internal floor space and ensure that heat, odors, and contaminants are discharged directly into the atmosphere, far away from fresh air intakes. EKG M&E Sdn Bhd specializes in the selection, high-static installation, and BOMBA-compliant maintenance of rooftop power ventilators.
We select the mechanical configuration based on the type of air being moved and the building's structural requirements.
These are the industry standard for commercial kitchens and high-heat industrial processes.
Vertical Discharge: The fan blows air straight up, preventing grease and hot air from accumulating on the roof surface, which protects the roofing membrane from degradation.
Grease Management: We install units with integrated grease collection trays and "Hinge Kits" to allow for the deep cleaning required for fire safety audits.
Ideal for moving massive volumes of air at lower pressures.
High CMH/CFM: We use these to "flush" large open-plan warehouses in the Klang Valley, significantly lowering the indoor heat index.
Weather-Proofing: Our installations include Automatic Gravity Shutters or motorized louvers that seal tight during Malaysia's heavy monsoon rains to prevent water ingress.
For Grade-A offices where aesthetics and noise are concerns.
Acoustic Treatment: We utilize "Low-Sone" rated fans and vibration isolators to ensure that mechanical hum doesn't vibrate through the concrete slab into the executive suites below.
As an HVAC and Clean Air Specialist, we ensure your rooftop fan is more than just a "spinning motor":
Variable Frequency Drive (VFD) Optimization:
We program the VFD to modulate the fan speed based on real-time demand. If your Carbon Dioxide (CO2) Sensors detect low occupancy, the rooftop fan slows down to save on TNB electricity costs.
Building Pressure Management:
A powerful rooftop fan can easily turn a building "Negative." We calibrate the exhaust speed to work in perfect harmony with your Building Fresh Air Intake, preventing "Whistling Doors" and the suction of humid outdoor air into your facility.
Smoke Spill Compliance:
For high-rise towers in KL, we provide rooftop fans rated for 250°C for 2 hours, ensuring life-safety compliance for emergency smoke extraction.
| Feature | Standard Utility Fan | EKG M&E Rooftop Grade |
| Casing | Thin GI / Plastic | Heavy-Gauge Galvanized / Aluminum. |
| Drive Type | Direct Drive | Belt Drive (Adjustable) or VFD. |
| Motor Protection | Basic | Class H / IP55 (Weather-proof). |
| Vibration | High | Spring-Isolated (Silent). |
Airflow Balancing and Commissioning: We perform a professional Duct Traverse at the roof level. We provide a technical report proving the fan is hitting its design Cubic Meters per Hour (CMH) setpoint.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide on-site vibration analysis, belt replacements, and motor troubleshooting for rooftop systems across the Klang Valley.
