Room Pressure Controllers from Triatek

TRIATEK VAV Controller - VAV 1000L

The TRIATEK VAV-1000L quickly and accurately controls airflow in laboratory zones that require pre-determined offsets between supply and exhaust air using proven TRIATEK control technology that can meet most airflow control requirements.

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. For more information, visit
