Weller vs Donaldson BOFA Fume Extraction: Which Is Right for Your Bench?
You've decided you need fume extraction — now which brand and system? A practical comparison of the two ranges we stock, by the job you're actually doing. From the Grove Sales technical team.
In this guide
1.First — both keep you COSHH-compliant
Solder fume (from rosin/colophony flux) is a respiratory sensitiser and a known cause of occupational asthma. Under COSHH you must control it at source — in practice that means LEV (Local Exhaust Ventilation): capturing fume at the tip or bench and filtering it (a HEPA filter for particulate plus a gas/carbon filter for the vapours). Both ranges do this properly. One to diarise: LEV needs a thorough examination and test roughly every 14 months. New to this? Start with our Do I Need Fume Extraction? guide.
2.Weller — integrated solder-fume extraction
Best when you run Weller soldering benches and want extraction that integrates with your irons.
- Tip extraction — add-on kits that clip to WXP irons (and the mobile Zero Smog 20T) to capture fume right at the tip.
- Bench / volume — Zero Smog 4V/6V (plus Guard and TL) for one-to-several workstations, with HEPA + gas filtration.
- A full range of extraction arms & nozzles and replacement filters.
Premium, tidy and purpose-built for solder fume.
3.Donaldson BOFA — scales beyond the bench (and beyond solder)
Best when you need more operators, enclosed/cabinet extraction, or you are extracting laser, 3D-printing or mechanical dust as well as solder fume.
- Volume — V200 (1 arm), V250 (2 arms), V600, V1000 iQ, Oracle iQ. Add operators as you grow; the iQ units add intelligent airflow monitoring and filter-status alerts.
- Fume cabinets — the FumeCAB range for enclosed work (conformal coating, potting, adhesives).
- Specialist — laser & dust, 3D printing, mechanical and dental.
Broader and more flexible — and often the more affordable entry for single/dual-arm volume extraction.
4.Side by side — which for which job
| Your situation | Weller | Donaldson BOFA |
|---|---|---|
| One Weller soldering bench | Tip-extraction add-on (clips to your iron) | V200 single-arm (affordable standalone) |
| A few soldering benches | Zero Smog 4V/6V volume unit | V250 dual-arm / V600 |
| Multi-operator line | Zero Smog 6V (premium) | V600 / V1000 iQ / Oracle iQ (scales + monitoring) |
| Enclosed / cabinet (coating, potting, adhesives) | — | FumeCAB range |
| Laser, 3D printing, mechanical dust | — | FumeKART / AD / 3D PrintPRO |
| Integrates with Weller irons | Yes (tip extraction) | Standalone arms/nozzles |
| Intelligent monitoring (airflow/filter) | Higher models | iQ range |
| Entry price for volume extraction | Premium | Lower (V-series) |
5.So which should you choose?
- Choose Weller if your world is soldering and Weller irons, and you want extraction that integrates at the tip or bench. Premium and purpose-built for solder fume.
- Choose Donaldson BOFA if you are scaling (more operators, cabinets), want the most affordable single/dual-arm volume units, need iQ monitoring, or you are also extracting laser, 3D-printing or mechanical dust. The broader, more flexible range.

6.FAQs
Do I legally need fume extraction for soldering?
If there is a risk of exposure to solder fume, COSHH requires you to control it at source — in practice, that means LEV extraction.
How often must it be tested?
An LEV system needs a thorough examination and test at least every ~14 months.
What filters do I need?
A HEPA filter for particulate plus a gas/carbon filter for the rosin and organic vapours; replace them per usage or the unit's indicator.
Can one unit cover several benches?
Yes — a volume unit with multiple arms, sized so the airflow matches the number of capture points.
What about laser or 3D-printing fume?
That needs different filtration — BOFA's specialist units (FumeKART, 3D PrintPRO) are built for it.
