Zero room air requirements. Hemco Corporation’s fume hood exhaust is equal to the auxiliary supply air, thereby zero room air is required. With the sash in the ½ open position and face velocity of 100 feet per minute, the cfm required equals the air supply. The hood exhaust air plus auxiliary air make up for room supply deficiencies. Auxiliary air fume hoods provide energy savings.

When there is a shortage of air in the lab, it is less costly to provide an auxiliary air fume hood system than to change or enlarge the whole building air handling system. With the sash in the ½ open position it only requires 50% supply air to make up for the exhaust air, making it 100% efficient with no room air required. Supply air ducting and remote blower required. Auxiliary Air fume hoods are available in 4’, 5’, and 6’ widths. All electrical components and services are UL and CSA listed. Shown with optional service fixtures, plumbing and electrical, airflow monitor, work surface and base cabinet.
