Basement air extraction

Basement Air Extraction by EKG M&E Sdn Bhd

In the deep basement levels of Kuala Lumpur and Selangor, air extraction is not just a comfort feature—it is a critical life-safety requirement. Because basements lack natural openings, they are prone to the accumulation of toxic vehicle emissions and, in the event of a fire, superheated smoke. Basement Air Extraction involves a high-powered mechanical network designed to flush out pollutants daily and perform Smoke Spill extraction during emergencies.

EKG M&E Sdn Bhd specializes in the engineering of these dual-purpose systems, ensuring your facility adheres to MS 1780, BOMBA regulations, and the Uniform Building By-Laws (UBBL).

The Dual-Mode Extraction Strategy

Our systems are engineered to switch modes seamlessly based on environmental triggers, ensuring safety while optimizing energy use.

1. Environmental Mode (CO & NOx Extraction)

During normal operations, the primary goal is to maintain air quality by removing Carbon Monoxide (CO).

• Sensor-Driven Logic: We integrate the extraction fans with CO sensors throughout the carpark. When levels reach a specific threshold (typically 25-50 ppm), the system activates or increases speed to clear the air.

• Stagnant Zone Prevention: Using 3D BIM Coordination, we calculate the "throw" of the supply air to ensure smoke and fumes are pushed toward the extraction grilles, eliminating "dead zones" where toxic gases can pool.

2. Emergency Mode (Smoke Spill)

In the event of a fire, the extraction system transitions to its maximum capacity to save lives.

• Negative Pressure Creation: The system creates a negative pressure zone to pull smoke away from escape routes like stairwells and elevator lobbies.

• FRL 120/120/120 Integrity: All extraction ductwork is constructed from 1.2mm heavy-gauge G.I. and encased in BOMBA-approved fire-rated boards or wraps. This ensures the system continues to extract 300°C–400°C smoke for at least 2 hours.

Critical Operational & Energy Benefits

As an M&E specialist focused on high-performance buildings, EKG ensures your extraction infrastructure is efficient:

• TNB Energy Efficiency (VFD Modulation):

  Running large extraction fans at 100% capacity 24/7 is a massive energy drain. We utilize Variable Frequency Drives (VFDs) that modulate fan speed based on real-time air quality. This significantly reduces your monthly TNB electricity bill.

• EECA 2024 Compliance:

  Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be energy-optimized. Our systems utilize high-efficiency motors and Class C Airtight ducting to prevent energy "leakage" through the joints.

• Corrosion Resistance:

  Basements are naturally damp environments. We utilize high-quality galvanized steel and specialized coatings to prevent rust, ensuring the structural integrity of your extraction network for decades.
