Welding fume extraction at a glance
| Question | Short answer |
|---|---|
| Why it matters | Welding fume is fine metal oxide particles and gases; stainless and alloy welding adds chromium and nickel compounds. Capturing it at the arc protects welders and keeps the shop clean |
| What the law asks | The Factories Act asks for exhaust appliances as near as possible to the point where fume is produced, and the Occupational Safety, Health and Working Conditions Code, in force since 21 November 2025, carries workplace health duties forward |
| Most common choice | A portable unit with one or two 2–4 m arms and a self-cleaning cartridge filter, on wheels, on 230 V single-phase or 415 V three-phase |
| Typical airflow | About 1,000–1,600 m³/h for one arm and 2,500–3,000 m³/h for two arms |
| Filter to ask for | Flame-retardant, PTFE-coated cartridge with a spark arrestor at the inlet |
| How we supply | Against order, sized to your welding process and bay layout, with filters and spares on order |
Types of welding fume extractor
Portable single-arm unit
One articulated arm of 2–4 m on a mobile unit with a cartridge filter. Moves between jobs and needs no ductwork; filtered air returns to the shop. For maintenance shops, job shops and occasional welding.
Portable dual-arm unit
Two arms from one fan and filter, covering two welders or both sides of a large job. Lower cost per welder than two single units.
Self-cleaning (pulse-jet) units
Compressed-air pulses knock dust off the cartridge so the filter keeps its airflow longer. The right choice for full-shift production welding; basic units without self-cleaning suit light, intermittent work.
Wall- or column-mounted arms
Fixed arms at each welding bay, connected by duct to a central filter. For fixed bays and production cells where the job comes to the welder.
Central extraction system
One large filter unit and fan serving many arms or hoods across a shop, often combined with grinding dust capture. Engineered from a site survey of bays, duct runs and duty.
Grinding and welding benches
Downdraft or back-draft benches that pull fume and grinding dust away from the operator on small parts. See industrial dust collectors.
How to size and specify it
| Point | What to check |
|---|---|
| Process | MIG/MAG and flux-cored welding make more fume than TIG; stainless and coated steel need the best filtration |
| Airflow | About 1,000–1,600 m³/h per arm at the hood; more arms or long ducts need a larger fan |
| Arm length and hood | 2–4 m arms; keep the hood close to the arc, because capture falls away quickly with distance |
| Filter | Flame-retardant PTFE-coated cartridge, spark arrestor at the inlet, and a filter-clogging indicator or differential-pressure gauge |
| Cleaning | Pulse-jet self-cleaning for daily production; manual-clean cartridges for light duty |
| Supply and noise | 230 V single-phase units suit small shops; 415 V three-phase for larger units. Check the noise level where welders work |
| Running cost | Cartridge life depends on welding hours and process; keep spare cartridges so a change does not stop work |

Frequently Asked Questions
Is welding fume extraction required by law in India?
The Factories Act requires effective measures against the inhalation and accumulation of dust and fume, with exhaust appliances applied as near as possible to the point of origin where practicable. The Occupational Safety, Health and Working Conditions Code, 2020, in force since 21 November 2025, carries workplace health and safety duties forward, with state rules being notified. A local extractor at the arc is the most direct way to meet these duties in a welding shop.
What airflow does a welding fume extractor need?
A single arm typically needs about 1,000–1,600 m³/h at the hood, and a two-arm unit about 2,500–3,000 m³/h. Long arms, long ducts and central systems need more fan capacity. The hood must be kept close to the arc, because capture drops quickly as the hood moves away.
What filter should a welding fume extractor have?
For welding, ask for a flame-retardant cartridge, ideally PTFE-coated for fine fume and easy cleaning, with a spark arrestor at the inlet. Stainless and alloy steel welding needs high-efficiency filtration because of chromium and nickel compounds in the fume.
What is the difference between a basic and a self-cleaning extractor?
A basic unit has a cartridge that is cleaned or replaced by hand and suits intermittent welding. A self-cleaning unit uses pulses of compressed air to clean the cartridge automatically, so airflow stays steady through the shift and the cartridge lasts longer. For full-time production welding, self-cleaning is worth the extra cost.
Portable unit or central system?
Portable units suit job shops, maintenance work and changing layouts because they move with the job and need no ductwork. Fixed arms and central systems suit production shops with fixed bays, where one larger filter is cheaper to run per welder. Many shops combine both.
Do you supply replacement filter cartridges?
Yes. Replacement cartridges and spares are supplied on order for the units we supply, and we recommend keeping one spare set so a filter change does not stop welding.
