How do I know if my fume hood and extraction system is working effectively?

An effective industrial fume hood should consistently capture fumes, dust and mist at the source, keeping them out of the operator’s breathing zone and the surrounding workspace. Signs of poor performance include visible haze or smoke in the air, residue buildup on nearby surfaces, or uneven airflow around the hood opening.

Performance depends on both the hood design and the dust collector’s airflow and filtration efficiency. If airflow has decreased, filters may be clogged, ductwork may be leaking, or the hood may not be properly sized or positioned for the process. Routine inspection, airflow testing and maintenance are essential to ensure safe, compliant and energy-efficient operation.
