Our Welding Fume Extraction Systems Range
The full range of welding fume extraction systems from Ador Welding — supplied with batch certificates, OEM authorisation documentation, and rate-contract pricing for bulk and recurring requirements.
On-Torch MIG-Gun Extractor
Integrated extraction at the torch tip — captures fume at the source. For semi-automatic MIG/MAG welding. Typical airflow 90-150 m³/h per gun. Used in production cells where individual welder protection matters.
Mobile Single-Arm Extractor
Portable cart-mounted unit with 2-3 m articulated arm and fan + HEPA filter. Used for short-term jobs, training, or where multiple stations rotate. Typical airflow 800-1500 m³/h. HEPA filtered exhaust returns to room — no ductwork to outside required.
Mobile Double-Arm Extractor
Two articulated arms on a single mobile unit — for two-welder bays. Higher fan capacity (1500-2500 m³/h). Cost per workstation lower than two single units.
Wall-Mounted Extraction Arms
Permanent wall-mount or column-mount articulated arms feeding into a central duct system. Used in fixed welding cells where the torch position is consistent.
Centralised Multi-Station System
Plant-wide ducted system serving 10-50+ welding stations from a single rooftop fan and pulse-jet bag-filter or cartridge-filter dust collector. Required for large fabrication shops and shipyards. Engineered case-by-case after a site survey.
Cartridge-Filter Dust Collector
Self-cleaning pulse-jet cartridge collectors — 99.9% efficiency on welding fume particles down to 0.3 µm. For systems serving 15-100+ stations. Cartridge change every 12-24 months at typical duty.
Filter Cartridges & Spare Bags (consumables)
Stock of replacement HEPA cartridges, polyester bags, and pre-filters for the major systems we install. Same-day dispatch within Telangana / AP.

Frequently Asked Questions
Why do welding shops need fume extraction?
Welding fume contains particles of manganese, chromium, nickel, iron oxides, and gases (carbon monoxide, ozone, nitrogen oxides) that cause acute and chronic worker health problems. ACGIH (American Conference of Governmental Industrial Hygienists) sets TLV-TWA limits (manganese 0.02 mg/m³, hexavalent chromium 0.0002 mg/m³, nickel 1.5 mg/m³). Indian regulations under IS 11829 and the Factories Act require fume extraction in welding workshops. Beyond compliance, extraction reduces sick-leave, improves productivity, and is increasingly required by export-oriented customer audits.
On-torch vs mobile vs centralised — which do I need?
On-torch is best for production cells with continuous welding at fixed positions — captures fume right at the source, lowest energy use per gun, but only works for MIG/MAG (not stick or TIG). Mobile extractors (single-arm or double-arm with HEPA) are best for occasional welding, training facilities, and shops where stations move around — no installation cost, but higher per-station energy. Centralised systems are required for shops with 10+ continuous welding stations — highest CapEx but lowest per-station operating cost. We do a site survey to recommend the right combination.
What airflow do I need per welding station?
Rule of thumb: 800-1500 m³/h per single welding station for capture-at-source extraction (mobile arm or wall-mounted arm). On-torch extractors need only 90-150 m³/h per gun because the capture is much closer to the source. Centralised systems are sized at 600-1000 m³/h per station with appropriate ducting design. Below 600 m³/h capture velocity drops below 0.5 m/s and fume escapes the hood. We do site engineering before quoting.
Do I need HEPA filtration or can I just exhaust outside?
Two options. (1) Discharge to atmosphere — requires roof exhaust, 10 m clearance from nearest air-intake, and may need pollution-control board clearance under the Air Act 1981. (2) HEPA-filtered recirculation — captures particulate, returns clean air to the workshop, no atmospheric discharge required. Recirculation is preferred for most modern factories because it conserves heated/cooled workshop air (large energy saving in summer). HEPA cartridges need replacement every 12-24 months at typical duty.
How much does a welding fume extraction system cost?
Mobile single-arm units start around ₹1.2-2 lakh per unit. Mobile double-arm units around ₹2-3.5 lakh. On-torch extractors ₹40k-60k per gun. Centralised systems are engineered to project — typical 20-station central system with cartridge collector is ₹15-25 lakh installed. We do free site survey and quote — typically takes 7-10 days for a site visit + design.
Do you provide installation, commissioning and air-quality verification?
Yes. For mobile units: same-day installation and operator handover. For centralised systems: full project — site survey, system design, fabrication, installation, commissioning, airflow verification, and post-installation air-quality measurement at welder breathing-zone level (sampling + lab analysis to confirm ACGIH TLV compliance). We provide the air-quality report for your safety records.
What ongoing maintenance is required?
On-torch: nozzle clearing weekly, pre-filter check monthly. Mobile units: pre-filter change every 200-400 working hours, HEPA every 12-24 months. Centralised systems: pulse-jet cartridge cleaning is automatic; manual cartridge replacement every 18-24 months at typical duty. Annual airflow verification recommended. We supply consumable cartridges and bags from stock — same-day dispatch within Telangana / AP for our installed customer base.
