Biological Safety Cabinet, Class 2, Type A2

Biological Safety Cabinet, Class II, Type A2, is used to protect personnel safety, product safety and external environment. It is a kind of air purification equipment providing dustless and sterile working environment, and the contaminated air in working area is exhausted via special filter channel under control, avoiding the harm to person and environment. It is 70% recirculation and 30% air exhaust.


  • It is designed to performance requirements of the NSF/ANSI49, EN 12469, and YY0569.
  • Main body is made of steel with white oven-baked epoxy-polyester.
  • Negative-pressure surrounds dual side walls to prevent the possibility of contamination from leaks to the exterior environment.
  • Stainless steel, grade 304 single-piece work tray has no welded joints to collect contaminants or rust. It developed further to ensure easier cleaning with normal cleaning solvents.
  • Single piece stainless steel back wall and side wall has no welded joints to collect contaminants or rust, easy to clean.
  • Side air grilles length along the height of the cabinet.
  • Front glass window, is made of hardened/ laminated safety glass, and provides protection from explosion and UV with more comfortable viewing.
  • Supply and exhaust ULPA filtration technology by Swedish Camfil Farr provide 99.999% typical efficiency for particle size of 0.1 to 0.2 microns.
  • German made ebm-papst motors automatically compensates for normal power line variation, air disruption and filter loading.
  • UV lamp for sterilization with interlocking safety switch function is designed for your safety.
  • LCD is mounted at eye level for at-a-glance viewing of airflow, operating parameters, and alarm messages.  The intuitive interface delivers a constant read-out of working area temperature, air velocity/volume, filter life span, total running time.
  • There is alarm systems, lights, sounds, and error messages for safety.
  • HFsafe-LC series has 4 sizes as follows:
