Fume Hoods Manufacturers

Fume hood or fume cupboard is a scientific equipment commonly used in chemistry laboratories designed to limit exposure to hazardous fumes. It protects users from inhaling chemicals by constantly pulling air into the hood and exhausting it out of the building. It also provides protection in the event of an explosion or fire. Two main types of unit exist, ducted and recirculating. With the ducted type, old asbestos vent pipe has been superseded on health grounds, typically with PVC or polypropylene. Air is drawn from the front of the cabinet by a fan, and expelled either outside the building, or made safe through filtration and fed back into the room. It is used when handling chemicals with significant vapor pressure or working with compounds that have an offensive odor.
