A Vientiane exhaust hood (often referred to as a flexible fume exhaust arm or local extractor hood) is a localized air extraction system designed to remove harmful fumes, vapors, smoke, and airborne contaminants directly at the source of generation in laboratory environments.
The name "Vientiane" may be a transliteration or regional term often used in China to refer to these flexible or articulated exhaust arms.
A typical Vientiane exhaust hood includes the following parts:
Hood/Nozzle:
Often made of polypropylene (PP) or acrylic (PMMA) for chemical resistance.
Available in various shapes: dome, bell, square, or slotted.
Flexible Arm:
Made of PVC, aluminum alloy, or polypropylene, with multiple joints and adjustable sections.
Equipped with friction joints, locking handles, or spring-assisted mechanisms for stability and positioning.
Mounting Base:
Options include wall-mount, ceiling-mount, or bench-mount.
Designed to anchor the exhaust arm securely and support movement.
Exhaust Duct Connection:
The rear end connects to an exhaust duct or blower fan.
Duct diameters usually range from Ø75mm to Ø150mm, depending on air volume requirements.
Localized Fume Capture: Captures contaminants right at the source before they disperse into the room.
Improved Air Quality: Minimizes exposure to hazardous fumes for lab personnel.
Highly Adjustable: The articulated arm allows for precise positioning, 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: Arm fixed to the wall, ideal for side workstations.
Ceiling-Mounted: Offers full flexibility and clears bench space.
Bench-Mounted: Directly fixed onto lab tables for close-range extraction.
| 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 |
