In the high-density built environment of Kuala Lumpur and Selangor, fire safety is a balance of two forces: the removal of toxic air and the injection of fresh air. Pressurized Smoke Extraction is a sophisticated dual-action strategy. It involves mechanically extracting smoke from the fire floor (Smoke Spill) while simultaneously injecting fresh air into escape routes (Staircase Pressurization) to prevent smoke ingress.
EKG M&E Sdn Bhd specializes in the design, installation, and integration of these systems to ensure a "smoke-free" tenable environment in strict accordance with MS 1780, MS 1472, and BOMBA regulations.
Pressurized smoke extraction works by creating a calculated pressure imbalance that favors the escape routes and restricts the fire zone.
The Goal: To suck out heat and toxic gases from the fire compartment (lobbies, corridors, or basements) to keep the smoke layer above head height.
Engineering: We utilize 1.2mm heavy-gauge G.I. ducting with a 2-hour fire rating (FRL 120/120/120). These ducts are liquid-tight and smoke-tight, ensuring that hot gases are safely transported to the discharge point without leaking into other floors.
The Goal: To inject fresh air into the escape stairwell to create a 50 Pa (Pascal) pressure shield.
Engineering: This pressure physically "pushes back" smoke. When a fire door is opened by an evacuee, the air velocity (typically 1.0 m/s) acts as a "wash" that prevents smoke from entering the sanctuary of the stairwell.
As a BOMBA-Compliant M&E Specialist, EKG ensures your pressurized systems are as efficient as they are safe:
TNB Energy Efficiency (VFD Optimization):
These systems are often powered by heavy-duty motors. By ensuring the ductwork is Class C Airtight, we eliminate static pressure loss. This allows your Variable Frequency Drive (VFD) to maintain target pressures at lower motor frequencies (Hz) during mandatory weekly tests, 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 energy-optimized. Our precision-engineered systems prevent "over-blowing," which can waste energy and make fire doors difficult to open (exceeding the 110 N force limit).
BOMBA Inspection Readiness:
A common failure point in KL high-rises is the seal at wall penetrations. We utilize BOMBA-approved intumescent fire stopping at all junctions, ensuring a hermetic seal that prevents smoke from bypassing the extraction or pressurization zones.

Total 3D BIM Coordination: We utilize 3D modeling to route heavy fire-rated extraction and pressurization ducts through crowded ceiling voids, ensuring zero "clashes" with sprinklers or structural beams.
Turnkey BOMBA Submission: We assist in the preparation of technical drawings and conduct mandatory Smoke Tests, Pressure Differential Tests, and Anemometer Airflow Verification for your Fire Certificate (FC) application.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional audits and technical proposals for shopping malls, data centers, and Grade-A office towers across Malaysia.
