The Gelman Synerflow General Purpose Fume Hoods are designed to provide a high degree of personnel and environment protection when handling hazardous chemical and fume removal in the laboratory.
Embodying advanced system-monitoring and controls technology, excellent aerodynamic designs, enhanced airflows, ergonomics and styling, Gelman Synerflow General Purpose Fume Hoods are manufactured to the most exacting standards for safety and containment in a wide range of laboratory applications.
The glassfiber reinforced plastics (GRP) used in the construction of the chamber and baffles has very low water absorption characteristics, along with excellent resistance to flame and the splash or spill of acids, weak bases and aliphatic hydrocarbons. The GRP with a flame-spread rating of 25, is asbestos-free with low smoke generation when exposed to flame.
The Gelman Synerflow General Purpose Fume Hoods maintain an average face velocity of 0.5 m/s through the work access opening.
An effective air barrier between the operator and the work chamber, maintained by an inward flow of room air into a full-width work access opening provides personnel and environment protection.
The barrier air blends with the odours and toxic chemical contaminants released within the work chamber and is totally exhausted to the outside atmosphere via the building exhaust system.
All Synerflow General Purpose Fume Hoods are fitted with a standard by-pass system which minimizes fluctuations in face velocity as the sash is raised or lowered. The by-pass is designed so that as the sash is fully raised, it is completely sealed off to provide optimum extraction through the sash opening for maximum containment. As the sash is closed, the air entering the fume hood through the sash and by-pass openings is redistributed, eliminating high velocity air streams in the near closed sash position.
