Laboratory air extraction

Laboratory Air Extraction by EKG M&E Sdn Bhd

In the high-stakes research environments of Kuala Lumpur and Selangor, air extraction is the primary line of defense against hazardous chemical exposure. Unlike general building ventilation, Laboratory Air Extraction must be engineered as a precision "source-capture" system. It must maintain negative pressure, ensure specific face velocities at containment devices, and handle a volatile mix of corrosive, toxic, and flammable vapors without material failure.

EKG M&E Sdn Bhd specializes in engineering these high-integrity systems, ensuring your facility remains compliant with DOSH LEV (Local Exhaust Ventilation) standards, ASHRAE 110, and DOE (Department of Environment) mandates.

The Three Pillars of Lab Air Safety

A professional lab extraction system is composed of three synchronized subsystems to ensure 100% containment and neutralization.

1. Capture at the Source (Fume Hoods & Snorkels)

Efficiency starts with capturing contaminants before they enter the room’s ambient air.

• Chemical Fume Hoods: The primary containment device for high-risk mixing. We calibrate these to maintain a steady 0.5 m/s face velocity.

• Articulated Extraction Arms (Snorkels): Used for localized capture at lab benches for tasks like soldering, microscopy, or minor chemical transfers.

• Biosafety Cabinets (BSC): Integrated extraction for biological research that requires both personnel and product protection.

2. Corrosion-Proof Transport (PVC / PP / FRP)

Since laboratory fumes are often highly acidic or solvent-rich, the ducting must be chemically inert.

• uPVC & Polypropylene (PP): Our standard for most research labs. These materials are molecularly welded to ensure a hermetic seal (ATC 6 Compliant).

• FRP (Fiberglass Reinforced Plastic): Utilized for large-diameter header ducts and high-pressure systems where extreme structural strength is required.

• Non-Shedding Integrity: Unlike metal, these polymers do not flake or corrode, ensuring the air path remains cleanroom-compatible.

3. Targeted Neutralization (Scrubbers & Carbon)

Exhausting toxic fumes directly into the atmosphere is a regulatory violation.

• Wet Scrubbers: For labs using mineral acids ($HCl$, $H_2SO_4$), we integrate scrubbers that "wash" the air stream with neutralizing reagents.

• Activated Carbon Adsorption: The gold standard for removing VOCs (Volatile Organic Compounds) and pungent odors from solvents.

Energy Efficiency & Operational Excellence

As a specialized M&E contractor, EKG ensures your lab extraction system supports both safety and the EECA 2024 energy mandates:

• VAV (Variable Air Volume) Optimization:

  Lab air extraction is energy-intensive. We utilize fast-acting VAV dampers and Variable Frequency Drives (VFDs). When a fume hood sash is lowered, the system automatically ramps down the fan speed, directly reducing your monthly TNB electricity bill while maintaining safety.

• Negative Pressure Protocol:

  We engineer the system to keep the lab at a slightly lower pressure than the corridors. This ensures that if a spill occurs, air flows into the lab, preventing the spread of contaminants to other parts of the building.

• Zero-Leakage Guarantee:

  Using molecular welding techniques, we ensure the entire extraction path is leak-proof, protecting maintenance personnel working in the ceiling voids or plant rooms.
