Bench top fume hood

Bench top or table top fume hood is a system used to filter and/or exhaust gases, vapour or chemical fumes. Work bench is extensively used in various laboratories like chemical, microbiological, analytical and educational laboratories. It is resistant to large number of aggressive chemicals. The fume hood can be either ductless or ducted type.

Ducted fumed hoods are used to store and experiment the hazardous fumes, chemicals and vapour. Application such as high volumes of organic solvents and heavy powder uses bench top type. They provide transparent walls for optimum visibility and polypropylene spill tray for strong chemicals.

Ductless fume hood helps to dissipate and remove low concentration fumes from work area. They have built in blower where vapours, fumes are collected through perforations and cleaned, contaminant free air is released into the laboratory space.

These fume hoods are box-like type with vertical or horizontal sash window. The negative pressure will be maintained which prevent the ability of contaminates from going out.
