Learn how to measure and maintain the standardized face velocity across the opening of the fume hood, and the different standards and requirements for fume hoods in india and abroad. The calculation for the cfm of a fume hood is obtained by multiplying the face opening (window of the fume hood) and the face velocity. Alue is the maximal open width x height. The minimum acceptable velocity for each hood face cell shall be 100 lfm. Per 8 ccr 5154.2(c), laboratory fume hoods shall provide a minimum average effective face velocity of 100 feet per minute. Face velocity is the velocity of the air that is sucked into the fume hood from around the user breathing zone. Face velocities too high or to low can be detrimental to. “general air flow should not be turbulent and should be relatively uniform throughout the laboratory, with no high velocity. Laboratory fume hoods should be so located within the laboratory to avoid crosscurrents at the fume hood face due to heating, cooling or.
