| Esco Launches New Microprocessor-Controlled Laminar Flow Cabinets |
| 2013-12-15 |
Esco launched the new range of Airstream Horizontal and Vertical Laminar Flow Cabinets (AHC-_D_, AVC-_D_ models) with the Sentinel Delta(TM) Microprocessor Control, Airflow Monitoring System.
Laminar flow cabinets must operate within a specific airflow envelope in order to provide optimum product and cross contamination protection. Low airflow can lead to ingress of external contamination into the work zone, or compromise cross contamination protection. Excessive airflow may cause similar undesirable effects. Contamination can result in experimental failures, leading to rework and loss of productivity.
For decades, conventional cabinets have used pressure gauges to monitor the pressure drop across the HEPA/ULPA filter, as a means of monitoring operating status. Filter pressure drop does not correlate with airflow, since pressure drop increases as filters load.
With the development of reliable, temperature-compensated, cost-effective air velocity sensors, Esco has made airflow monitoring standard on its range of Airstream Horizontal and Vertical Laminar Flow Cabinets. Unlike commercial solutions on the market, Esco proprietary sensors have been developed in-house and specifically optimized for airflow velocities typical on laminar flow cabinets.
Airstream Cabinets feature German made ebm-papst permanently lubricated, centrifugal motor/fans with external rotor designs. Esco ULPA filters operate at a typical efficiency of >99.999% at 0.1 to 0.3 micron sizes, providing superior product protection over conventional HEPA filters. Esco cabinets provide ISO Class 3 air cleanliness within the work zone as per ISO 14644.1, significantly cleaner than the usual Class 5 classification on clean benches offered by the competition.
External surfaces are powder coated with Esco Isocide to eliminate 99.9% of surface bacteria within 24 hours of exposure. Soft touch controls for blower, light, outlet and UV are easy to clean. An angled front, curved work surface front edge, and glass sides promote ergonomics. The spill-retaining work top design with a recessed central area contains accidental liquid spills.
Airstream Laminar Flow Cabinets are available in 0.6, 0.9, 1.2, 1.5, 1.8m widths, in both horizontal airflow and vertical airflow configurations. For more information, download the brochure at: http://www.escoglobal.com/biotech/PDF/AHC&AVC_A4_Standard.pdf.
