The Triatek VAV-1000L quickly and accurately controls airflow in laboratory zones that require pre-determined offsets between supply and exhaust air. Applications include temperature control, room exhaust air control, and room supply air control.
Exhaust CFM from fume hoods and general exhaust from a laboratory zone are summed by the VAV-1000L to calculate total exhaust CFM, which is subtracted from the supply airflow CFM to calculate net airflow for the zone.
Where net negative pressure for containment purposes is required, the VAV-1000L modulates supply airflow to be less than the total exhaust airflow.
The VAV-1000L constantly monitors conditions and adjusts the airflow by modulating the air valve or damper in order to maintain the desired negative pressure. Zone temperature can also be controlled using a temperature transmitter.
