In the high-humidity environment of Kuala Lumpur and Selangor, a Louvered Fresh Air Intake is the critical "entry point" for your building’s ventilation system. Its primary M&E function is to allow the necessary volume of outside air ($CMH$) into the building while physically blocking rain, debris, and pests.
EKG M&E Sdn Bhd specializes in engineering and installing intake systems that maintain Indoor Air Quality (IAQ) without compromising the building's envelope or increasing the cooling load on your Chiller or AHU.
The most significant challenge for air intakes in the Klang Valley is "Water Entrainment"—where heavy tropical rain is sucked into the ductwork by high-velocity fans.
We utilize "Drainable" or "Triple-Bank" louver designs.
The Physics: These louvers feature internal vertical gutters. As wind-driven rain hits the blades, the water is channeled into a side frame and drained away before it can enter the airstream.
If the air moves too fast through the intake, it will pull in moisture and noise.
The Solution: We calculate the "Face Velocity" (typically kept below 2.5 m/s) to ensure a smooth, quiet intake. We then program your Variable Frequency Drive (VSD/VFD) to compensate for the Static Pressure drop caused by the louver blades and insect screens.
As an HVAC and Clean Air Specialist, we treat the intake louver as the first stage of a total building ecosystem.
Positive Pressure Shield:
We calibrate your intake volume to be slightly higher than your exhaust volume. This creates a Positive Pressure environment, which physically prevents "unfiltered" street dust and humid KL air from leaking in through gaps in doors or windows.
Filtration Interlock:
Fresh air intakes are often paired with a PAHU (Primary Air Handling Unit). We install G4 or F7 pre-filters behind the louvers to capture urban pollutants and PM2.5 before the air is distributed to your staff or guests.
| Feature | Standard Architectural Louver | EKG M&E Industrial Intake |
| Water Rejection | Basic (Leaks in heavy rain). | High (Storm-Resistant/Drainable). |
| Pest Protection | Plastic mesh (Breaks easily). | SS304 Bird & Insect Screening. |
| Airflow Efficiency | Low (High Resistance). | Aerodynamic (Low Static Pressure). |
| Material | Thin Aluminum. | Heavy-Duty Galvanized / Powder Coated. |
Airflow Balancing and Commissioning: We perform a professional Duct Traverse and Static Pressure Audit post-installation to verify your building is receiving the correct Air Change Rate (ACR) as per DOSH (JKKP) guidelines.
Total System Integration: We ensure your intakes are located safely away from Kitchen Ecology Unit discharges and cooling tower plumes to prevent "Cross-Contamination."
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide turnkey design and scheduled "Clean Air" maintenance for shopping malls, hotels, and industrial warehouses.
