Ductless Fume Hood, as the name explains itself, such kind of fume hoods are designed without duct and fitted with variety of filters to filter out hazardous fumes and smoke in order to protect operators and surrounding environment. Depending upon the level of severity of hazardous fumes and chemicals; several types of filters are used such as carbon filter, HEPA filter, Ammonia Filter and Formaldehyde filter. The core aim of a ductless fume hood is to recirculate clean air. These fume hoods without duct can also be used in highly sensitive areas; hence, they offer energy saving, infrastructure cost reduction, and flexibility and more over environment protection.
We are ductless fume hood manufacturers in India. We make these fume hoods in both benchtop and floor standing designs. Floor standing ductless fume hood cabinets come with chemical storage cabinet at bottom. Each cabinet is supplied at factory price India with complete installation, commissioning and training; in addition, we also provide immediate after sales support throughout India with life time spare parts availability guarantee.
