Carbon Filter for Filtrabox Fume Extractors

Why Add an Activated Fume Extractor Carbon Filter

Laser welding can release vapors and odors depending on material prep and coatings. While the F9 Prefilter and 99.999% HEPA filter remove particulate, gases require a dedicated Fume Extractor Carbon Filter. A packed bed of activated carbon provides a large internal surface area that traps molecules through adsorption. As a result, you reduce nuisance smells and improve operator comfort without sacrificing airflow.

How the Carbon Stage Works in Your Laser Welding System

Air passes through particulate filters first so dust does not prematurely load the carbon media. Next, the activated carbon bed targets odors and gas-phase compounds. Consequently, the system can maintain capture velocity at the hood while returning cleaner smelling air to the workspace. This three-stage design aligns with good ventilation practice for local exhaust systems serving welding tasks.

Construction and Performance Details

• Media: High-activity granular activated carbon optimized for vapor phase adsorption.
• Capacity: Deep carbon bed maximizes dwell time and holding capacity while maintaining stable pressure drop.
• Cartridge: Rigid, leak-resistant housing supports consistent sealing and easy service.
• Integration: Installs downstream of F9 and HEPA stages for best gas removal performance.

Best Practices, Maintenance, and Breakthrough

Unlike particulate filters, carbon performance declines when adsorption sites become saturated. Differential pressure does not indicate gas saturation. Replace the Fume Extractor Carbon Filter based on operating hours, odor breakthrough, and process conditions. Keep upstream F9 and HEPA stages on schedule to protect the carbon bed and extend its life. For consistent results, log changeout dates and note any process changes that increase vapor generation.

Typical Applications

• Laser welding of oiled, painted, or coated metals where odors are present.
• Jobs using solvents or cleaners near the welding station.
• Shops seeking improved comfort by reducing nuisance smells along with particulate control.
