Topair’s Educational Fume Hood has transparent sides and a transparent back for 360° visibility, serving educational sessions. Topair’s Polypropylene Fume Cupboards are made of high-quality non-corrosive polypropylene with excellent chemical resistance. Polypropylene increases the product’s tensile strength and improves its thermal characteristics. The Polypropylene Fume Cupboards protect laboratory staff from noxious fumes released by acids, dangerous gas and organic solutions – materials and acids which regular steel hoods may not withstand. Harmful and unpleasant chemical fumes are removed from the controlled environment to facilitate a safe and pleasant work environment. The Fume Cupboard channels chemical vapors out of the building using an external fan installed on the roof or on an external wall. The cupboards are designed for work with heavy chemicals, and have been independently tested to meet the requirements of EN-14175, ASHRAE 110-1995 standards.
