Thermac’s new Digital Flow Meter provides the user with a clear display of the actual real-time  airflow performance of each Negative Pressure Unit – gives greater accuracy when ensuring the correct negative pressure is maintained within an enclosure.

The Meter highlights variations in airflow when, for example, filters are loaded, ducting is fitted or when roving heads are used for localised extraction.
