A Vientiane exhaust hood (often referred to as a flexible fume exhaust arm or local extractor hood) is a localized air extraction system meticulously engineered to efficiently remove harmful fumes, vapors, smoke, and airborne contaminants directly at their source of generation, ensuring a safer laboratory environment.
The term "Vientiane" is a transliteration or regional designation commonly used in China to describe these versatile and articulated exhaust arms.
A typical Vientiane exhaust hood is composed of the following essential parts:
Hood/Nozzle:
Often constructed from polypropylene (PP) or acrylic (PMMA) for superior chemical resistance.
Available in a diverse array of shapes: dome, bell, square, or slotted.
Flexible Arm:
Fabricated from PVC, aluminum alloy, or polypropylene, featuring multiple joints and adjustable sections for dynamic reach.
Outfitted with friction joints, locking handles, or spring-assisted mechanisms to ensure stability and precise positioning.
Mounting Base:
Includes options for wall-mount, ceiling-mount, or bench-mount.
Engineered to securely anchor the exhaust arm and support its movement with stability.
Exhaust Duct Connection:
The rear end seamlessly connects to an exhaust duct or a blower fan.
Duct diameters typically range from Ø75mm to Ø150mm, tailored to air volume specifications.
Localized Fume Capture: Efficiently captures contaminants right at the source, preventing their dispersal into the room.
Improved Air Quality: Significantly reduces exposure to hazardous fumes, safeguarding laboratory personnel.
Highly Adjustable: The articulated arm facilitates precise positioning, allowing coverage of 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 affixed to the wall, perfect for side workstations.
Ceiling-Mounted: Provides complete flexibility and frees up bench space.
Bench-Mounted: Directly attached to 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 |
