In the subterranean and semi-enclosed structures of Kuala Lumpur and Selangor, carpark exhaust ducting is the most critical mechanical component for both daily air quality and emergency life safety. Because vehicles continuously emit Carbon Monoxide (CO) and other pollutants, the exhaust network must act as the building's "lungs," flushing out toxic fumes during normal operations and switching to high-volume Smoke Spill extraction in the event of a fire.
EKG M&E Sdn Bhd specializes in the engineering, installation, and balancing of these heavy-duty systems, ensuring compliance with MS 1780, UBBL, and BOMBA regulations.
A professionally installed exhaust network is designed to handle two very different airflow regimes using a single set of fire-rated conduits.
Goal: To remove vehicle exhaust fumes and prevent the buildup of hazardous gases.
Mechanism: The ducting is linked to Carbon Monoxide (CO) sensors. Through a Variable Frequency Drive (VFD), the system modulates fan speed based on real-time air quality.
Layout: Using 3D BIM Coordination, we position exhaust grilles at both high and low levels. This is vital because while CO has a similar density to air, other pollutants and cold smoke can pool at lower levels.
Goal: To extract 300°C–400°C smoke to maintain visibility and a tenable environment for evacuation.
FRL 120/120/120 Integrity: We utilize 1.2mm heavy-gauge galvanized steel (G.I.) encased in BOMBA-approved fire-rated boards or high-density wraps. This ensures the duct remains structurally sound for at least 2 hours under extreme heat.
Negative Pressure: The exhaust system creates a negative pressure zone that pulls smoke away from "positive pressure" escape routes like stairwells.
As a specialized M&E contractor, EKG ensures your exhaust infrastructure is optimized for efficiency:
TNB Energy Efficiency (Leakage Control):
Leaky exhaust ducts force fans to work harder to maintain airflow. By ensuring a Class C Airtight installation, we eliminate static pressure loss. This allows your fans to hit safety targets at lower frequencies (Hz), directly reducing your monthly TNB electricity bill.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized for minimal waste. Our precision-engineered systems prevent energy "bleeding" and ensure your Building Energy Index (BEI) remains within regulatory limits.
Acoustic Treatment:
High-volume exhaust can be noisy. We integrate Acoustic-Lined Ducts and silencers to ensure that mechanical "fan roar" does not disturb upper-floor occupants or violate local noise ordinances (e.g., DBKL/MBPJ).
| Feature | Standard HVAC Ductwork | EKG Carpark Exhaust Ducting |

Total 3D BIM Coordination: Carpark ceilings are the most crowded areas for services. We model the exhaust network in 3D to ensure zero "clashes" with sprinklers, plumbing, and electrical trays, preserving maximum vehicle headroom.
Turnkey BOMBA Submission: We manage the full process, from technical drawings to performing the mandatory Smoke Tests and Anemometer Airflow Traverse required for your annual Fire Certificate (FC) renewal.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional safety audits and technical proposals for shopping malls, Grade-A office towers, and luxury condominiums.
