A Vientiane exhaust hood (often referred to as a flexible fume exhaust arm or local extractor hood) is an advanced localized air extraction system meticulously designed to efficiently remove harmful fumes, vapors, smoke, and airborne contaminants directly at their source in laboratory environments.
The term "Vientiane" may be a transliteration or a regional term frequently used across China to describe these flexible or articulated exhaust arms.
A typical Vientiane exhaust hood is composed of essential parts, including:
Hood/Nozzle:
Skillfully crafted from polypropylene (PP) or acrylic (PMMA) for superior chemical resistance.
Available in a variety of shapes: dome, bell, square, or slotted to suit diverse needs.
Flexible Arm:
Engineered from PVC, aluminum alloy, or polypropylene, it features multiple joints and adjustable sections for optimal reach.
It comes equipped with friction joints, locking handles, or spring-assisted mechanisms ensuring stability and precise positioning.
Mounting Base:
Versatile options include wall-mount, ceiling-mount, or bench-mount.
Designed to securely anchor the exhaust arm, facilitating smooth and stable movement.
Exhaust Duct Connection:
The rear end seamlessly connects to an exhaust duct or blower fan.
Duct diameters typically range from Ø75mm to Ø150mm, tailored to air volume requirements.
Localized Fume Capture: Effectively captures contaminants right at their point of origin before they disperse into the surrounding environment.
Improved Air Quality: Significantly reduces exposure to hazardous fumes, ensuring a safer atmosphere for lab personnel.
Highly Adjustable: The articulated arm boasts precise positioning capabilities, adeptly covering multiple work areas with a single hood.
| Component | Common Materials | Features |
|---|---|---|
| Hood | PP, PMMA, PC | Chemical-resistant, transparent |
| Arm Tubing | PVC, Polypropylene, Aluminum Alloy | Rigid, durable, chemical-safe |
| Joints & Connectors | Nylon, PP, ABS | High strength, adjustable |
| Gaskets | Silicone or EPDM | Airtight sealing |
Wall-Mounted: The arm is fixed to the wall, making it ideal for side workstations, maximizing space.
Ceiling-Mounted: Provides full flexibility while clearing valuable bench space for other tasks.
Bench-Mounted: Securely fixed onto lab tables, ensuring close-range extraction for efficient operation.
| Model Size | Arm Length | Hood Diameter | Duct Size | Airflow Rate |
|---|---|---|---|---|
| Small | 1.5 m | Ø250 mm | Ø75 mm | ~120-180 m³/h |
| Medium | 2.0 m | Ø300 mm | Ø100 mm | ~200-300 m³/h |
| Large | 2.5 m+ | Ø350 mm | Ø125-150 mm | ~300-500 m³/h |
