Tek Air HVAC Flow Meter
Tek-Air has provided laboratory airflow control systems since our incorporation in 1983. The experience gained through the completion of hundreds of installations, for a wide variety of customers, is reflected in our design philosophy. Our design for each project is intended to embody the following key elements of this philosophy.
Be it airflow, space pressure, or face velocity; if a parameter is important enough to be controlled, it should be measured directly. Most competitors of fume hood controls measure sash open area only and then position a calibrated mechanical volume regulator (springs, bearings, and levers) to achieve volumetric flow control.
