In the research and diagnostic hubs of Kuala Lumpur and Selangor, commercial laboratories handle a diverse array of hazardous substances—from volatile solvents and corrosive acids to infectious biological agents. A Safety Exhaust System is not merely a ventilation duct; it is a life-safety critical infrastructure designed to capture, contain, and neutralize airborne contaminants before they reach the breathing zone of lab personnel or the surrounding environment.
EKG M&E Sdn Bhd specializes in the engineering and certification of laboratory ventilation, ensuring your facility complies with JKKP (DOSH) USECHH Regulations, ASHRAE 110, and EN 14175 standards.
As an HVAC and Clean Air Specialist, we focus on the "Capture Velocity" at the face of the containment device to ensure no chemical "escape" occurs.
Constant Air Volume (CAV): Best for labs with consistent chemical loads. The exhaust remains at a fixed rate, providing high reliability but higher energy costs.
Variable Air Volume (VAV): The gold standard for modern KL labs. By integrating Variable Frequency Drives (VFDs), the system modulates the exhaust volume based on the sash height of the fume hood. This reduces energy consumption by up to 50% during idle periods.
High-Efficiency Particulate Air (HEPA) Integration: For microbiology and clinical labs, we integrate certified HEPA filtration banks to capture 99.97% of pathogens ($0.3$ microns) before the air enters the main exhaust manifold.
Standard materials fail quickly in a laboratory environment. We utilize high-performance materials to ensure system longevity:
Corrosion-Resistant Ductwork: We install PPS (Flame-Retardant Polypropylene) or FRP (Fiber Reinforced Plastic) ducting. These materials are impervious to the acidic and solvent vapors common in chemical synthesis and pathology labs.
Effluent Treatment (Scrubbers & Carbon): To meet Department of Environment (DOE) Clean Air standards, we integrate Vertical Packed Bed Scrubbers for acid vapors or Activated Carbon Adsorption for organic solvents.
Stack Discharge Velocity: We design high-plume exhaust fans that "jet" the filtered air high above the building's roofline to prevent "re-entrainment" into the building’s fresh air intakes.
A commercial lab exhaust system must be "intelligent" to handle fluctuating demands:
| Control Feature | Benefit | EKG M&E Implementation |
| Sash Position Sensing | Safety & Energy Savings. | VFD ramps motor speed based on sash height. |
| Static Pressure Control | System Stability. | Maintains constant negative pressure in the duct. |
| Redundancy (N+1) | Uninterrupted Safety. | Automatic switch-over to standby fan on failure. |
| BMS Integration | Real-time Monitoring. | Modbus/BacNet alerts for low-flow alarms. |
In Malaysia, Local Exhaust Ventilation (LEV) systems must be inspected annually by a JKKP-registered Competent Person. Our service includes:
Face Velocity Testing: Ensuring fume hoods maintain the required 0.5 m/s (100 fpm) airflow.
Smoke Visualization: Physically proving that the airflow is laminar and that no "dead zones" or turbulence exist that could trap gases.
Vibration Analysis: We perform vibration checks on high-speed exhaust fans to prevent structural noise and premature bearing failure in rooftop assemblies.
Turnkey Engineering: We manage the entire loop—from the fume hood on the bench to the chemical scrubber on the roof.
Regulatory Compliance: Based in Kuala Lumpur, we ensure your lab is ready for JKKP (DOSH) audits and DOE environmental inspections.
Specialized Maintenance: We offer 24/7 support for critical labs, including HEPA filter integrity testing (DOP) and chemical pump servicing for scrubbers.
