In the industrial and laboratory sectors of Kuala Lumpur and Selangor, managing hazardous vapors is a critical safety and regulatory requirement. Unlike standard ventilation, Chemical Fume Extraction must be engineered to capture, transport, and neutralize toxic, corrosive, or flammable gases before they can enter the breathing zone of personnel.
EKG M&E Sdn Bhd specializes in "Source-Capture" engineering, ensuring your facility remains compliant with DOSH (Department of Occupational Safety and Health) and DOE (Department of Environment) standards.
A high-performance extraction system operates as a closed loop to ensure zero environmental or workplace leakage.
The most efficient way to manage fumes is to capture them at the point of origin.
Laboratory Fume Hoods: Enclosed workspaces with constant inward airflow to prevent chemical vapors from escaping.
Snorkel / Articulated Arms: Flexible extraction points used for localized chemical mixing or soldering, allowing for precision capture without obstructing the workflow.
Face Velocity Calibration: We ensure capture velocities meet the 0.5 m/s industry standard, preventing "vapor escape" caused by cross-drafts in the facility.
Because chemical fumes are often acidic or alkaline, the ducting must be chemically inert.
Non-Metallic Materials: We utilize PVC, Polypropylene (PP), or FRP ducting. These materials do not rust or pit, ensuring a 25-year service life even when transporting concentrated hydrochloric or sulfuric acid vapors.
Hermetic Sealing: Using solvent welding or thermal extrusion, we ensure the system is Airtightness Class 6 (ATC 6) compliant to prevent leaks into the ceiling void.
Exhausting untreated fumes into the atmosphere is a violation of the Environmental Quality Act.
Wet Scrubbers: Fumes pass through a "packing media" sprayed with a neutralizing liquid (reagent), scrubbing the chemicals out of the air stream.
Activated Carbon Modules: Used for organic solvents and VOCs (Volatile Organic Compounds), where specialized carbon pellets adsorb chemical molecules.
As a specialized M&E contractor, EKG ensures your extraction system supports both safety and the EECA 2024 energy mandates:
TNB Energy Efficiency (VFD Optimization):
Fume extraction requirements fluctuate based on production load. We pair our extraction fans with Variable Frequency Drives (VFDs), allowing the system to ramp down when hoods are not in use, directly reducing your monthly TNB electricity bill.
DOSH & DOE Ready:
We provide all necessary technical documentation, including airflow traverse reports and static pressure calculations, required for your annual Local Exhaust Ventilation (LEV) testing and DOE written notifications.
Zero-Condensation Drainage:
In Malaysia’s humidity, chemical vapors can condense inside the duct. Our systems are installed with specialized PVC/FRP Drain Points and pitched runs to ensure corrosive liquids are safely channeled to your wastewater treatment plant.

Total 3D BIM Coordination: We model extraction paths in 3D to ensure perfect integration with chemical storage, production lines, and structural supports for a "clash-free" installation.
Turnkey Validation: We provide full Testing & Commissioning (T&C), including smoke testing and anemometer validation, to prove the effectiveness of the capture zones.
Strategic Regional Support: Based in Kuala Lumpur, we provide professional audits for semiconductor plants, electroplating facilities, pharmaceutical labs, and chemical manufacturing centers across Malaysia.
