• True vertical laminar airflow with a large filter covering the entire work zone within the cabinet for better protection against cross contamination, as compared to conventional dead-air boxes.
• High-quality polyester pre-filter and main HEPA filter with a typical efficiency of 99.9998% at 0.3 microns provide the best product protection in the world; typical ULPA filter life span is more than 3 years depending on operating conditions and total number of hours in usage.
• Esco Sentinel™ Microprocessor Control provides users flexibility and full configurability according to the requirements of the user.
• Admin PIN can be set on the control to restrict unauthorized access to menu parameters.
• UV decontamination cycle is fully programmable using the Microprocessor keypad; a timer will turn off the UV lamp after the set period of time.
• Unique pre-filter change alarm and UV lamp replacement alarm make the cabinet the safest and the most user-friendly PCR cabinet on the market.

Airflow

• During operation, room air is drawn through the top of the cabinet via a pre-filter, with 85% arrestance, trapping larger particles and increasing the life of the main filter.
• The air is then forced evenly through the main HEPA filter resulting in a unidirectional stream of clean air that is projected vertically over the internal work zone. All airborne contaminants are flushed and diluted, resulting in a particulate-free work environment.
• The purified air then leaves the main work chamber across the open front of the cabinet.
• The average airflow velocity of 0.30 m/s (60 fpm) in PCR-3A and PCR-4A models ensures that cleanliness is maintained in the work zone with 35-38 air changes per minute.
