In the high-rise landscape of Kuala Lumpur and Selangor, the staircase air supply system is the primary "oxygen line" for the building’s escape routes. These specialized systems are designed to deliver high volumes of fresh air into stairwells to create the life-saving pressure differential required to keep smoke out.
EKG M&E Sdn Bhd provides high-performance, fire-rated air supply solutions that strictly adhere to MS 1472, BOMBA standards, and the Uniform Building By-Laws (UBBL).
Distributing air throughout a vertical shaft requires a system that can handle high static pressure while remaining completely airtight and fire-resistant.
Because air supply ducts travel through multiple fire compartments to reach the stairwell, they must be protected against external fire exposure.
Integrity & Insulation: We encase the galvanized steel (G.I.) ducts in BOMBA-approved fire-rated boards or high-density wraps. This ensures that even if a fire occurs on a lower floor, the air delivered to the upper floors remains cool and smoke-free.
Stability: Reinforced hanger systems and seismic-rated supports ensure the duct does not buckle or collapse under the intense thermal stress of a fire.
Multi-Point Injection: In high-rise buildings, air is not just dumped at one point. We install supply outlets at regular intervals (typically every 3 floors) to ensure a uniform pressure of 50 Pa throughout the entire height of the stairwell.
Opposed Blade Dampers (OBD): Every discharge point is fitted with adjustable dampers to balance the airflow, preventing "over-pressurization" near the fan and "under-pressurization" at the furthest points.
As a BOMBA-Compliant M&E Specialist, EKG ensures your air supply infrastructure supports long-term building performance:
TNB Energy Efficiency (Airtight Construction):
Poorly sealed ducts waste air into ceiling voids, forcing the fan to run harder. By ensuring a Class C Airtight installation, we allow your Variable Frequency Drive (VFD) to maintain safety standards at lower frequencies (Hz). This directly reduces your monthly TNB electricity bill during mandatory weekly testing.
EECA 2024 & Building Compliance:
Under the Energy Efficiency and Conservation Act (EECA) 2024, mechanical air transport must be optimized for minimal leakage. Our precision-sealed fire ducts protect your Building Energy Index (BEI).
Tenability & Occupant Safety:
By maintaining the correct air velocity (typically 1.0 m/s across open doors), the supply system ensures that the stairwell remains a "breathable sanctuary," providing the critical window of time needed for safe evacuation.
| Feature | Standard Ventilation | EKG Fire-Rated Air Supply |
| Pressure Rating | Low Static | High Static (Positive Pressure) |
| Airtightness Class | Class A / B | Class C / D (High Performance) |
| Fire Protection | None | Mandatory (FRL 120/120/120) |
| BOMBA Required | No | Mandatory for High-Rise FC |
| Joint Sealing | Standard Mastic | Certified Intumescent Sealant |
Total 3D BIM Coordination: Stairwell shafts are often tight and shared with wet risers and electrical conduits. We utilize 3D modeling to route air supply ducts with zero "clashes," ensuring optimal placement for uniform air distribution.
Turnkey BOMBA Submission: We provide all technical documentation and conduct the mandatory Pressure Differential Test and Anemometer Airflow Traverse required for your Fire Certificate (FC).
Strategic Regional Support: Based in Kuala Lumpur, we provide professional air supply audits and installations for Grade-A office towers, luxury condominiums, and hospitals across Malaysia.
