3,000 m³/h cartridge dust collector for hand-held laser welding and metal dust

Built for hand-held fiber laser welding and fiber cutting — the fine metal powder that would clog a HEPA filter in weeks. PTFE membrane cartridges with pulse back-blow cleaning.
Fine conductive metal particles can arc inside an electrostatic cell. PTFE membrane cartridges are the industry-standard tool for welding and metal dust.
Four solenoid valves reverse-blow each cartridge automatically, knocking dust off so airflow stays high through long welding runs.
PTFE cartridges rinse clean and last 12–24 months — far cheaper than replacing disposable HEPA filters every few weeks.
Welding smoke, metal dust, and grinding particulate → FH-8 Series (PTFE). Oil smoke, VOCs, and sticky non-metal fume → 12 Series (ESP).

What can the FH-8S extract?
Hand-held fiber laser welding fume (1–3 kW), fiber laser cutting, precision cutting, grinding, and soldering.
FH-8 vs FH-8S — which do I need?
FH-8 (1,000 m³/h) suits a single welding station. FH-8S (3,000 m³/h) is the upgraded build for heavier welding and continuous operation. For multi-station shops, see FH-8-3 / FH-8-4.
Do the cartridges need replacing?
Yes, every 12–24 months, once pulse cleaning stops restoring airflow.
Is the airflow adjustable?
Yes — programmable pulse cleaning and adjustable airflow via the control panel.
What about CE and warranty?
CE certified with a 12-month warranty. Documents available on the Downloads page.
