A Class II BSC is a ventilated enclosure designed to provide protection for personnel, the environment, and the product. It achieves this through a combination of inward airflow, HEPA-filtered downflow, and HEPA-filtered exhaust.
Class II Cabinets are typically used for work with biosafety level 1, 2, and 3 agents. They are not suitable for BSL-4 pathogens.
Certification should be carried out at least annually, or after any relocation, filter replacement, or major maintenance. Certification ensures that airflow and HEPA filters meet performance standards. AES Environmental is able to provide NATA certification to all models of Biological Safety Cabinet in Australia.
Regular maintenance of a Biosafety Cabinet is critical to ensure safety and sterility of products. AES provides a comprehensive range of maintenance services including:
• Mechanical Inspection: This includes the motor/ blower unit, vibration mountings, switch functions, gaskets, pre-filters and HEPA filters.
• Check for System Integrity: Challenge for filter leakage to AS 1807:2021 Cl 4.4 and AS 1807.7
• Integrity of work zone: Test for induced air leakage in the work zone.
• Prevent cross contamination in the work area: check and adjust air velocity and uniformity of airflows.
• Establish HEPA filter life and performance: measure static pressure of filters and electronic motor current.
• Check environment factors: measure light output, sound level and germicidal ultraviolet lamp efficiency.
• Repair and adjust to specification: when necessary and whenever possible, on-site repairs are included in our services.
