In the fire safety architecture of KL and PJ skyscrapers and shopping malls, the Smoke Spill Fan is the most critical mechanical component for life safety. Unlike standard ventilation fans, these are engineered to operate in extreme conditions to "flush" toxic gases out of the building. EKG M&E Sdn Bhd provides high-performance smoke spill solutions that meet the stringent BOMBA and Uniform Building By-Laws (UBBL) requirements.
A high-temperature smoke spill fan is designed to maintain its structural integrity and rotational speed even when the air passing through it exceeds 250°C.
Class H Insulated Motors:
We utilize motors with Class H insulation, specifically certified to run for a minimum of 2 hours at 250°C. This ensures the fan does not "seize" or burn out during the most critical window of an evacuation.
Aerodynamic Axial Design:
Most smoke spill systems utilize Axial Flow Fans because they can move massive volumes of air (high m3/s) at the high static pressures required to pull smoke through long runs of fire-rated ducting.
Fire-Rated Power Supply:
As an M&E specialist, we ensure these fans are wired with fire-resistant cables and connected to the building’s essential power circuit (Genset) via an Automatic Transfer Switch (ATS).
A smoke spill fan is only as effective as the logic that triggers it. We integrate these units into the Building Management System (BMS) and Fire Alarm Panel with specific "Emergency Mode" protocols:
VFD Fire-Mode Override:
While we use Variable Frequency Drives (VFDs) to save energy during normal "air-purging" cycles, the system features a Fire-Mode Trigger. Upon a smoke signal, the VFD bypasses all internal motor protections (which would normally trip the fan to prevent damage) to ensure it runs until the fire is suppressed or the motor fails mechanically.
Replacement (Make-Up) Air Interlock:
To prevent the building from becoming a "vacuum"—which would make exit doors impossible to open—our fans are interlocked with motorized fresh air louvers. For every cubic meter of smoke exhausted, a cubic meter of fresh air is introduced at a low level.

HVAC & Clean Air Specialist: We perform the Static Pressure Calculations required to ensure the fan is powerful enough to overcome the resistance of fire-rated dampers and ducting, guaranteeing the mandatory 10 Air Changes Per Hour (ACH).
Testing and Commissioning (T&C): We don't just "install and leave." We conduct Smoke Visualization Tests to prove to building owners and authorities that the extraction path is functional and effective.
Klang Valley Strategic Support: Based in Kuala Lumpur, we provide professional maintenance, vibration analysis, and annual BOMBA-readiness audits for smoke spill systems across the Klang Valley.
