Class II microbiological safety cabinets are part of the latest generation of laminar airflow systems (LAF) from Faster, where high quality materials ensure compliance with the highest safety standards. Designed and built to the performance requirements of European Standard EN-12469: 2000 and American Standard NSF / ANSI 49. 70% of the air will be returned to the safety cabinet through the HEPA / ULPA main class H14 filter. The remaining 30% are discharged via a HEPA / ULPA class H14 exhaust air filter.
