Ducted vs. Ductless Fume Extractors: Which is Right for Your Workplace?

Fume extractors come in two types: ducted and ductless. Ducted fume extractors use a system of ducts to remove contaminated air from the workplace and expel it outside, while ductless fume extractors use a filtration system to purify the air before recirculating it back into the workplace. Which type of fume extractor is right for your workplace? Here are some factors to consider:

Contaminant type and concentration
Ducted fume extractors are better suited for workplaces with high concentrations of hazardous substances, such as welding fumes or chemical vapors. Ductless fume extractors are better suited for workplaces with low to moderate concentrations of contaminants, such as laboratories or medical facilities.

Airflow requirements
Ducted fume extractors require a strong airflow to effectively remove contaminated air from the workplace. Ductless fume extractors require a lower airflow, as they recirculate the air back into the workplace. If your workplace requires a high airflow, a ducted fume extractor may be the better option.

Cost and maintenance
Ductless fume extractors are generally less expensive than ducted fume extractors, as they do not require ductwork. However, they require more frequent filter replacements and maintenance. Ducted fume extractors require less frequent maintenance but may require more upfront costs for ductwork installation.

By considering these factors, you can determine which type of fume extractor is best suited for your workplace.”
