LabGard ES (Energy Saver) CYTO Class II, Type A2 Biosafety Cabinet

Description

The LabGard ES CYTO, model NU-581, is a console-style laminar flow biosafety cabinet designed for cytogenetic and similar applications requiring containment. It is classified as a Class II, Type A2 cabinet, providing personnel, product, and environmental protection. A key operational feature is its Energy Saver DC ECM motor system, which uses a forward-curved fan and a solid-state controller with digital airflow sensors. This system maintains a constant inflow velocity, automatically compensating for filter loading and voltage fluctuations to ensure consistent performance and energy efficiency. The cabinet maintains a minimum inflow velocity of 105 feet per minute (0.53 meters per second) through the work opening. Its airflow pattern involves HEPA-filtered downflow air that mixes with inflow air in a common plenum, with approximately 30% of the air exhausted after HEPA filtration and 70% recirculated. All contaminated ducts and plenums are maintained under negative pressure for safety. This cabinet is suitable for work with biological agents and minute quantities of non-flammable volatile chemicals or radionuclides used in microbiological studies, though such applications require proper external exhaust.
