Fume hood is one such protective laboratory equipment in the laboratory systems that plays a major role in providing ventilation by eliminating exposure to volatile liquids, dusts and mists. It is a cabinet with a moveable front sash made out of safety glass that dilutes the polluted air caused in the experiments and ventilates the laboratory by filtering the same. A Fume-hood helps secure and protect the lab workers from explosive reaction and filters their inhalation.

Basic Fume Hood Design for Lab Safety Sai Systems
Fume hood is one such protective laboratory equipment in the laboratory systems that plays a major role in providing ventilation by eliminating exposure to volatile liquids, dusts and mists. It is a cabinet with a moveable front sash made out of safety glass that dilutes the polluted air caused in the experiments and ventilates the laboratory by filtering the same. A Fume-hood helps secure and protect the lab workers from explosive reaction and filters their inhalation.
Basic Information Fume hood design is a crucial aspect while considering lab safety. The two major types of fume hood designs can be differentiated by the different manners that occur while using them for venting the contaminated air. While ducted fume hoods use the buildings existing HVAC ductwork to vent air to the outside, ductless fume hoods pass the air through a charcoal filter to trap contaminants and then returns the cleaned air to the room. Whichever type of fume hood you use, make sure it is rated for the temperature, volume and chemicals of your lab systems with looking for its SEFA certification seal. The Scientific Equipment and Furniture Association (SEFA) works with laboratory owners, architects, contractors and others to advance the goal of creating a safe lab environment that ensure the safety of lab employees and the quality of your results.
Let’s now evaluate the multiple factors that help you decide whether your laboratory need ducted fume hoods or ductless fume hoods. Ducted fume hoods are great for use building’s existing ductwork which can handle a variety of chemicals. These fume hood are stationary with a fixed position in the lab. Ducted fume hoods are available in a wide range of standard sizes, for you to choose the best for your lab. Ducted fume hoods include- a wide variety of countertop options that can stand up to any range of chemicals or temperatures, sinks and electrical outlets. Existed buildings with inaccessible ductwork requires Ducted fume hoods as these fume hoods procedure few chemicals. Ductless fume hoods are self- contained, filtered laboratory enclosures that efficiently cleans fumes, particles and vapour and delivers it back into the workspace.
