Laboratory Fume Hood

About Laboratory Fume Hood

Laboratory Chemical Fume Hood is a ventilated enclosure designed to protect laboratory personnel from inhaling hazardous chemical fumes, vapors, and dusts by safely containing and exhausting them away from the breathing zone. It is one of the most essential safety devices in chemical laboratories.

1. Work Chamber:

   • The internal workspace where chemical operations are performed.

   • Often lined with chemical-resistant materials like epoxy resin or stainless steel.

2. Sash (Front Window):

   • A vertically or horizontally sliding tempered glass panel.

   • Protects the user while allowing controlled access to the workspace.

3. Exhaust System:

   • Uses an electric blower or fan to draw air into the hood and out through a duct or filter system.

   • Ensures constant airflow to prevent fume escape.

4. Airfoil and Baffles:

   • Optimize airflow across the work surface and direct contaminants toward the exhaust.

5. Lighting:

   • Built-in, vapor-proof lighting provides clear visibility inside the hood.
