How to Choose the Right Fume Extraction Arm
Picking the perfect lab fume extraction arm does not have to be complicated. When you have a clear plan, the process is straightforward. Making the right choice from the start ensures your equipment performs safely and meets the demands of your specific tasks. We have put together a simple five step checklist to guide you.
5-Step Checklist for Selecting Your Fume Arm
- Identify Your Contaminants: First, list every chemical, vapor, or dust particle you need to capture. This is the most important step. Always consult your Safety Data Sheets (SDS) to understand the hazards and check for material compatibility.
- Determine Reach and Mounting: Measure your workspace. You need to know the length and articulation required to cover all work areas without being an obstacle. This is also when you will decide if a bench, ceiling, or wall mounted model makes the most sense for your lab’s layout.
- Verify Material Compatibility: Refer to your contaminant list from Step 1. This list dictates the arm material you need. For general solvents, an aluminum Original Exhaust Snorkel is a solid choice. For strong acids, you will need a polypropylene Chemical Resistant Exhaust Snorkel. For delicate electronics, an ESD Exhaust Snorkel is necessary to prevent static discharge.
- Confirm Airflow Requirements: Ensure the arm’s diameter and your building’s ventilation system can generate the necessary capture velocity. This is the air speed at the source needed to pull contaminants into the arm. Check your system’s CFM (cubic feet per minute) capacity to confirm it is adequate.
- Review Hood and Accessory Options: The final step is choosing a hood style that fits your application. Different jobs call for different capture patterns, with options like dome, flat, or slotted hoods. Also consider extras like dampers for airflow control or integrated lighting.
