A Vientiane exhaust hood (often referred to as a flexible fume exhaust arm or local extractor hood) is a highly efficient localized air extraction system meticulously designed to adeptly remove harmful fumes, vapors, smoke, and airborne contaminants right at their source of generation in sophisticated laboratory environments.
The term "Vientiane" might be a transliteration or a regional term prevalently used in China to describe these versatile flexible or articulated exhaust arms.
A typical Vientiane exhaust hood encompasses the following meticulously crafted parts:
Hood/Nozzle:
Often constructed from polypropylene (PP) or acrylic (PMMA) to ensure superior chemical resistance.
Available in an array of shapes: dome, bell, square, or slotted, to cater to diverse needs.
Flexible Arm:
Crafted from PVC, aluminum alloy, or polypropylene, featuring multiple joints and adjustable sections for enhanced operational flexibility.
Equipped with friction joints, locking handles, or spring-assisted mechanisms to ensure stability and precision positioning.
Mounting Base:
Options include wall-mount, ceiling-mount, or bench-mount.
Engineered to anchor the exhaust arm with utmost security while supporting seamless movement.
Exhaust Duct Connection:
The rear end is designed to impeccably connect to an exhaust duct or blower fan, ensuring efficient ventilation.
Duct diameters typically range from Ø75mm to Ø150mm, tailored to meet specific air volume requirements.
Localized Fume Capture: Expertly captures contaminants right at the source, preventing them from dispersing into the room.
Improved Air Quality: Significantly minimizes exposure to hazardous fumes, safeguarding the health of lab personnel.
Highly Adjustable: The articulated arm offers exceptional precision in positioning, efficiently covering multiple work areas with a singular 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 firmly affixed to the wall, making it ideal for side workstations.
Ceiling-Mounted: Provides comprehensive flexibility while clearing bench space.
Bench-Mounted: Securely mounted onto lab tables for close-proximity 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 |
