Fume hoods are recommended for exhaust from the hood working area of gases, vapour, toxic particles & odour to improve working environment of people who regularly handle toxic substances. Theese eqipment reduce personal exposures and odor level in the laboratory. The Fume Hoods are designed to exhaust toxic or otherwise harmful vapors etc. for protecting laboratory personnel & equipments. A motor-blower exhaust system generates negative pressure within the hood, extracting the contaminated air from the working area and expelling it outside the building atmosphere and thereby preventing the fumes spreading into the room.
