Fume Extraction Ducts

In the chemical and manufacturing corridors of Selangor and Kuala Lumpur, the safe removal of hazardous vapors is a critical safety and regulatory requirement. EKG M&E Sdn Bhd provides high-performance Fume Extraction Ducts, specifically engineered to capture and transport volatile organic compounds (VOCs), acid mists, and toxic gases. Our systems are designed to exceed 2026 DOSH (JKKP) safety standards, ensuring that harmful substances are neutralized at the source before they reach the operator's breathing zone.

Engineering Selection by Chemical Load

We specify ducting materials and aerodynamic profiles based on the chemical "aggressiveness," temperature, and concentration of the fumes being extracted.

1. Laboratory and Pharmaceutical Fume Hoods (High-Purity Extraction) Environments dealing with various reagents require a system that is both versatile and inert.

• Polypropylene (PP) and PVC Ducting: These materials are inherently resistant to a broad spectrum of acids and solvents. We utilize specialized solvent-welding or thermal-fusion joints to ensure a monolithic, leak-proof path that prevents chemical odors from escaping into the lab environment.

• Low-Noise Centrifugal Fans: To maintain a focused research environment, we integrate precision-balanced fans that provide the necessary suction with minimal acoustic disturbance.

2. Electronics and Semiconductor Soldering (Micro-Extraction) The removal of lead fumes and flux vapors requires a system that is high-velocity yet physically unobtrusive.

• Articulated Extraction Snorkels: We install flexible, multi-jointed arms that allow operators to position the suction hood exactly where the soldering occurs. These are integrated into a rigid manifold system to maintain consistent capture velocity across multiple stations.

• ESD-Safe Construction: All components are grounded to prevent Electrostatic Discharge (ESD), protecting sensitive electronic components from static damage during the extraction process.

3. Heavy Industrial Chemical Baths (Large-Scale Containment) Processes such as electroplating or chemical etching release massive volumes of corrosive mist that can destroy standard M&E infrastructure.

• FRP (Fiberglass Reinforced Plastic) Headers: For large-diameter primary headers, we utilize FRP. It combines the chemical resistance of plastic with the structural strength of steel, allowing for long, self-supporting spans across factory floors.

• Vinyl Ester Resin Liners: We specify high-performance resin liners that withstand aggressive "wet-acid" condensation, ensuring a 20+ year lifecycle in the most demanding environments.

Critical Installation and Integration

As an industrial M&E specialist, EKG ensures the fume extraction circuit is a precision-integrated safety component:

"Capture Velocity" Calibration: A fume extraction system is only effective if the air moves fast enough to pull vapors away from the operator. We utilize thermal anemometers to verify the Face Velocity at every hood and snorkel, ensuring compliance with ACGIH (American Conference of Governmental Industrial Hygienists) recommendations.

Demand-Controlled Ventilation (DCV): To reduce TNB electricity costs, we integrate Smart Damper Actuators and Variable Frequency Drives (VFDs). The system automatically detects when an extraction point is active and ramps up the main fan, providing suction only where it is needed and preventing the waste of conditioned factory air.

Scrubber and Treatment Coordination: To meet Department of Environment (DOE) discharge standards, fume-laden air must often be treated. We engineer the transitions and duct routing for Wet Scrubbers or Carbon Adsorption Units, ensuring the air-stream is properly conditioned for maximum neutralizing efficiency.
