In the fire safety landscape of Kuala Lumpur and Selangor, the smoke-spill system is the building's primary defense against the leading cause of fire-related fatalities: smoke inhalation. BOMBA Certified Smoke-Spill Ducting refers to a high-temperature mechanical extraction network designed to transport superheated, toxic gases out of a fire zone to maintain a tenable environment for evacuation and rescue operations.
EKG M&E Sdn Bhd specializes in the design, installation, and certification of these systems, ensuring strict adherence to MS 1780, UBBL, and the latest 2026 BOMBA enforcement standards.
To achieve certification for a Fire Certificate (FC) application, the ducting must meet rigorous mechanical and thermal benchmarks.
Under BOMBA regulations, smoke-spill ducts must remain structural and insulated for a minimum of 2 hours.
Integrity: The duct must not collapse or breach, ensuring smoke is contained within the system and not leaked into other floors.
Insulation: The external surface of the duct must not exceed specific temperature limits to prevent the "auto-ignition" of combustible materials in adjacent rooms.
EKG Solution: We utilize 1.2mm heavy-gauge galvanized steel (G.I.) encased in BOMBA-approved fire-rated boards or high-density fire wraps.
Smoke extraction involves air temperatures reaching 300°C to 400°C. Metal expands significantly at these levels.
Fire-Rated Hangers: We install reinforced support systems that accommodate thermal movement without losing structural stability.
Intumescent Seals: Every wall or floor penetration is treated with BOMBA-certified intumescent fire stopping that expands under heat to maintain a hermetic seal between fire compartments.
As a specialized M&E contractor, EKG ensures your certified ductwork supports building performance:
TNB Energy Efficiency (Class C Airtightness):
Leaky ducts force extraction fans to work harder to maintain the required airflow. By ensuring a Class C Airtight installation, we eliminate static pressure loss. This allows your Variable Frequency Drive (VFD) to run at lower frequencies (Hz) during mandatory weekly testing, 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 green compliance levels.
High-Temperature Fan Synergy:
Our ducting is designed to work in tandem with high-temperature axial or centrifugal fans. We ensure all connections utilize certified fire-rated flexible connectors to prevent vibration transfer while maintaining a fire-tight airway.
| Feature | Standard HVAC Ducting | EKG BOMBA Certified Ducting |
| Material Gauge | 0.5mm – 0.8mm GI | 1.2mm (Minimum) GI |
| Fire Resistance | None | Mandatory 2-Hour (FRL 120/120/120) |
| Operating Temp | Ambient (24°C - 35°C) | High-Temp (300°C - 400°C) |
| Airtightness | Class A / B | Class C / D (Precision Sealed) |
| BOMBA Required | No | Mandatory for High-Rise/Basement FC |
Total 3D BIM Coordination: Smoke-spill ducts are often the largest conduits in a building. We utilize 3D modeling to route these heavy ducts through crowded ceiling voids with zero "clashes" against sprinklers or structural beams.
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 data centers across Malaysia.
