Airstream® Class III Biosafety Cabinet

Esco Airstream® Class III biohazard safety cabinets offer the highest level of product, operator and environmental protection from infectious/biohazardous aerosols and are suitable for microbiological work with agents assigned to biological safety levels 1, 2, 3, or 4. Designed for an absolute level of containment, they are frequently used for work involving the deadliest biohazards, bacteria, viruses and microorganisms. Manufactured to meet and exceed the latest Class III biohazard safety cabinet requirements of the EN 12469:2000.

Product Highlights

• Exhaust air is double-filtered through high-quality ULPA filters (per IEST-RP-CC-001.3) with a rated efficiency of >99.999% for 0.1 to 0.3 micron particles, better than HEPA filters.
  


• Exclusive dual exhaust filters provide >100,000 times better protection than single-stage designs.



• Microprocessor-based Esco Sentinel™ Silver control system provides visual / audible alarms for airflow.



• Magnehelic pressure gauge* is mounted in the rear of the work zone for at-a-glance monitoring of operating pressure.



• Arm-length Neoprene™ gloves are chemical and flame resistant.



• An integrated pass-through with interlocking doors permits materials transfer without risk of environmental contamination.



• An angled cabinet front ensures an ergonomic working posture.



• Cabinet operates at negative pressure relative to the laboratory in order to prevent migration of pathogenic materials out of the work area.

Airflow Profile

Air taken in from above the cabinet passes through a pre-filter and an ULPA filter. Moving into the main chamber of the cabinet in a vertical air stream, it provides product protection from airborne particulate matter and cross contamination. This vertical flow air stream is also known as the downflow. Close to the work surface, the downflow air stream “splits” with a portion entering grilles towards the front or back of the cabinet, providing a uniform downflow over the entire working area of the chamber. Esco’s unique airflow design ensures that air within the cabinet is replaced consistently, eliminating excessive air turbulence and the accumulation of particulate contamination in “dead air corners”.

• Air is moved within the cabinet below the work table, where is passes through two ULPA filters; one mounted below the work table, and the other above the main chamber. This provides a fail-safe mechanism in case any one of the ULPA filters fails to maintain containment.
• Esco's unique blower system maintains negative pressure within the main work chamber under all circumstances. Unlike the competition, our Class III biohazard safety cabinets do not utilize supply blowers, which, when improperly balanced, may result in the working area being positively pressurized.
• All exhaust air is ULPA-filtered and exhausted directly back to the laboratory without re-circulation. Optionally, an exhaust collar can be fitted to allow air to be ducted via a dedicated ducting system to the external environment. Air velocity through an open glove port will be a minimum of 0.7m/s (140fpm) when a single port is open.
