Class II Biological Safety Cabinets Streamline Class II Biological Safety Cabinet Model SC2-4A_. Introduction Esco SC2 Class II Biological Safety Cabinets provide optimum performance which is continuously monitored and controlled by our user-friendly Sentinel™ Delta control system, allowing you, the user, a safe and reliable working environment. The angled front and glass side windows provide an ergonomic work environment for the user. the filter surface area to extend filter life and eliminate possible filter media damage by thin and sharp aluminum separators used in conventional HEPA filter construction. • The filter assembly is constructed in accordance with EN 1822 requirements. • The supply filter provides ISO Class 4 (per ISO 14644.1) clean air to the work surface in a gentle vertical laminar flow for product protection. • The supply HEPA filter and exhaust HEPA filter create a fully integrated performance envelope for product, operator and environmental protection. • The exhaust filter traps biohazard particles acquired from the work surface before air is exhausted to the room, offering personal and environmental protection. • Inflow of room air enters the front air grille to establish operator protection; room air does not enter the work zone, preventing product contamination. • The exhaust filter media is protected from mechanical damage by an integrated metal screen guard, which is absent from conventional HEPA filters. • The raised armrest prevents the operator from blocking the inflow grilles. User-Friendly Control System • The inflow velocity, downflow velocity, air flow path and intake geometry are precision tuned and tested to create an optimum air curtain at the front aperture. This curtain maintains operator and product protection even in the unlikely event of a severe inflow or downflow imbalance that would compromise protection in a conventional cabinet. • Safe - 1.2 m (4') model tested and certified to EN12469 at the Health Protection Agency, Porton Down, UK. Integrated Filtration System Independent supply and exhaust HEPA filters provide typical efficiency of >99.99% at 0.3 microns. Streamline filters meet the IESTRP-CC001.3 recommended practice for HEPA performance (USA), and EN 1822 for H13 performance (EU). • HEPA filters (per IEST-RP-CC001.3), are tested to a typical efficiency of >99.99% at 0.3 micron particles. • Modern separator-less mini-pleat filter construction maximizes The user-friendly Esco Sentinel Delta™ microprocessor-based control system, fitted in the SC2 cabinet, supervises the operation of all cabinet functions. The controls are configurable to meet user requirements. Enhanced features promote cabinet usability. • Accurate true airflow velocity sensing technology measures all critical cabinet airflow parameters allowing superior monitoring. The airflow sensor is temperature compensated to increase accuracy. • Solid state variable speed controllers offer superior control over conventional “step” controllers. • A bright, easy-to-read, LCD display provides continuous monitoring of cabinet airflow. • An additional UV-interlock ensures that the optional UV lamp is deactivated when the sash is not fully closed. • Audible and visual alarms ensure product, operator and environmental protection by alerting the user in the event of low airflow or unsafe sash positions.

Cabinet Filtration System ULPA/HEPA-filtered air Unfiltered / potentially contaminated air Dynamic air barrier, inflow and forward- directed downflow air converge Ambient air is pulled through the remainder moving to the rear air grille. A small portion of the ULPA filtered downflow enters the intake perforations at the side capture zones at a higher velocity (small blue arrows). perforations located towards the work zone front to prevent contamination of the work surface and work product. The inflow does not mix with the clean air within the cabinet work zone. Inflow air travels through a return...
