Guide to Fume Hood Selection Introduction Selection of the proper type of fume hood to use in a laboratory should be based upon two interrelated considerations: 1. The hood must allow the user to perform the work in a safe, efficient manner. 2. The need to reduce air conditioning cost.

The configuration of the hood should be such that containers can be moved in and out of the hood easily. The sash opening of the hood must allow...

Guide to Fume Hood Selection Face Velocity In a laboratory fume hood, the control of contaminants is achieved by drawing air through the face (sash) opening. The face velocity is defined as the average velocity of the air in this opening and is expressed in units of feet per minute (FPM). The Occupational Safety and Health Administration (OSHA) in its Laboratory Standard does not specify a required fume hood face velocity. As a result, hood users must look to published guidelines for recommendations on proper face velocities. The most authoritative of these published guidelines is the ANSI/AIHA...

Guide to Fume Hood Selection Baffle Design Fixed baffles come with fixed slots in the rear baffle. The size of the slots are optimized to provide the best performance for general purpose use.

This adjustment should only be done by someone familiar with hood air flows...
