Lab fume hood ducting

Lab Fume Hood Ducting by EKG M&E Sdn Bhd

In the research and testing facilities of Kuala Lumpur and Selangor, the ducting connected to a fume hood is the most critical safety link. It must transport concentrated hazardous vapors—ranging from volatile organic solvents to aggressive mineral acids—away from the chemist's breathing zone. Standard HVAC ducting is insufficient; lab-grade systems must be chemically inert, hermetically sealed, and engineered to maintain precise Face Velocity standards.

EKG M&E Sdn Bhd specializes in the engineering and installation of high-integrity fume hood exhaust networks, ensuring full compliance with DOSH LEV (Local Exhaust Ventilation) standards and ASHRAE 110 testing protocols.

Material Specialization for Laboratory Exhaust

The chemical profile of your lab dictates the material of the ducting to ensure a 25+ year service life without structural failure.

1. uPVC & CPVC (The Industry Standard)

• uPVC: The primary choice for most laboratories handling general acids (Hydrochloric, Sulfuric) and bases. It is lightweight and uses solvent welding for a leak-proof seal.

• CPVC: Utilized for high-temperature chemical processes or where fire-retardancy is a priority, maintaining integrity up to 90°C.

2. Polypropylene (PP)

• Best For: Laboratories handling aggressive organic solvents and high thermal loads. PP offers superior impact resistance and is thermal-welded to ensure zero-leakage in high-spec research environments.

3. Composite FRP (Fiberglass Reinforced Plastic)

• Best For: Heavy-duty industrial labs or systems requiring large-diameter headers. FRP combines chemical inertness with extreme structural strength, ideal for high-pressure exhaust systems and vertical stacks.

Critical Engineering & Safety Protocols

As a specialized M&E contractor, EKG ensures your fume hood ducting supports both safety and the EECA 2024 energy mandates:

1. Face Velocity & VAV Integration

To keep the chemist safe, the ducting must maintain a constant inward airflow (typically 0.5 m/s).

• Variable Air Volume (VAV) Ready: We integrate our ducting with fast-acting VAV dampers that modulate airflow based on the hood's sash position. This ensures safety while drastically reducing the volume of conditioned air exhausted, directly lowering your facility's energy costs.

2. Airtightness Class 6 (ATC 6)

A fume hood duct often passes through populated areas or ceiling plenums.

• Zero-Leakage Guarantee: We utilize molecular welding (solvent/thermal) to create a monolithic structure. Every system is pressure-tested to ATC 6 standards to ensure that toxic vapors are contained entirely within the air path.

3. Condensation & Wash-Down Management

• Pitch and Drain: We install ducting with a specific pitch back toward the hood or a dedicated carboy to prevent corrosive "puddling."

• Perchloric Acid Scrubber Ducts: For labs using perchloric acid, we engineer the system with internal wash-down nozzles to prevent the buildup of explosive perchlorate salts.
