What is Lab Fume Hoods?

The primary purpose of fume hoods in laboratories is to exhaust chemical fumes, vapors, gases, dust, mist, and aerosols.

To prevent contaminants from escaping the hood, it maintains a relatively negative pressure inside while drawing air through the hood opening at a constant rate. A suitable hood face velocity is crucial to achieving safe and effective fume hood operation. Excessive face velocities can reduce containment and create turbulence, but insufficient velocities can make hoods less effective. The important parts of a fume hood include baffles, hood body, sash, airfoil, face, exhaust plenum, and work surface.
