Ductless fume hoods, also known as filtered fume hoods or recirculating fume hoods. It draws away contamination generated on the work surface, including chemical fume, toxic vapors, gases, solvent, acid vapors, dust or pharmaceutical powder, etc. These harmful substances can be taken up by continuous airflow to the filtration system and be adsorbed there, recycling clean air back into the room. So no room air needs to exhaust, and no ductwork needs to construct. Energy saving and cost-effective. It usually comes with a standing or benchtop type. Customization is available.
