The Industry's Premier Biological Safety Solution from Esco featuring an inherently safe double-fan system, Esco Accuflow™ microprocessor-based motor speed controller, motorized sliding sash and many others. Extremely low noise level of less than 57dBA. Certified to DIN EN 12469 by TÜV-NORD , Germany for safety and performance (FC2-4A1 and FC2-6A1).

Features

·      Unique Dynamic Chamber™ plenum with angled filter delivers superb airflow uniformity with deviation no greater than 5% to 6% of average downflow, exceeding European Standard EN 12469 by more than three times.

·      Negative pressure plenum surrounds contaminated positive pressure plenum; no fabric bags are used.

·      Dual fan design for guaranteed safety. If one fan fails, operator protection is still maintained with only one fan running.

·      Esco next-generation Sentinel™ microprocessor supervises all cabinet functions.

·      A large easy-to-read digital display and ergonomically sized touchpad controls improve user interface.

·      Fully closable, motorized sash provides an airtight seal for better safety when cabinet is inoperative overnight.

·      The front sash is motorized for convenient one-hand operation. The sash control is mounted on the front control panel.

·      Integrated sash proximity contacts sense proper sash position, serve as an interlock for the UV lamp, and activate an alarm if the sash is improperly positioned.

·      When fully lowered the sash seals automatically against a closed-cell peripheral gasket to isolate the interior and prevent escape of contaminants during decontamination.

·      Frameless, shatterproof sash is easier to clean, offers larger, unobstructed viewing area.

·      Ergonomically angled front improves reach and comfort.

·      Multi-piece work surface removal simplifies cleaning. Single piece, spillage containing work surface is available as an option.

·      Raised armrest maintains safety by preventing blockage.

·      Esco ISOCIDE™ antimicrobial surface on all painted surfaces minimizes contamination.

·      Downflow air sensor mounted in interior.

·      Accuflow™ microprocessor speed controller maintains safe cabinet airflow despite supply voltage fluctuations.

·      Integrated RFI and electrical noise filters eliminate interference with and from adjacent equipment.

·      Low noise level <58dBA (1.2 meter (4’) cabinet) is significantly quieter than conventional cabinets.

·      Dual, long-life ULPA (per IEST-RP-CC001.3) filters for supply and exhaust airflow.

·      Enhanced side-capture zones optimize containment.

·      Independent exhaust sensor mounted exterior to work area.

·      Single piece side and back wall construction.

·      Improved lighting is brighter, more uniform and reduces glare.

·      Optional UV lamp operates on programmable timer.

·      HPV-compliant and approved for safe decontamination using BIOQUELL and STERIS technologies.

·          Ambient air is pulled through the 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 path toward the common air plenum (blower plenum) at the top of the cabinet.

·          Approximately 35% of the air in the common plenum is exhausted through the ULPA filter to the room. The remaining 65% of the air is passed through the downflow ULPA filter and into the work area as a vertical laminar flow air stream bathing the work surface in clean air.

·          The uniform, non-turbulent air stream protects against cross contamination within and throughout the work area.

·          Near the work surface, the downflow air stream splits with a portion moving toward the front air grille, and 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).

·          A combination of inflow and downflow air streams forms an air barrier that prevents contaminated room air from entering the work zone, and prevents work surface emissions from escaping the work zone.

·          Air returns to the common air plenum where the 35% exhaust and 65% recirculation process is continued.
