What Is The Importance Of Fume Hood Face Velocity?

The speed at which air is drawn into a fume hood is of great importance for the safe and effective operation of a fume hood. A speed that is too high or too low can compromise the performance of the fume hood, leaving those near the hood in danger. So why does this airspeed matter? What is so significant about the face velocity measurement of a fume hood? What is a Fume Hood Face? If we are going ...

Exhaled air dispersion distances during noninvasive ventilation via different Respironics face masks

Abstract Background: As part of our influenza pandemic preparedness, we studied the exhaled air dispersion distances and directions through two different face masks (Respironics; Murrysville, ...

Dual Range Air Flow Calibrators

If you require visual accuracy over a large flow range, or wish to calibrate a number of air flow units consisting of more than one flow range, select HI-Q’s Dual Range AFC. The Dual Range unit consists of two pressure differential gauges installed in a single cabinet, that precisely measures both the low and high rate of air through a single venturi.
