Horizontal Flow Laminar Hood

BZ Series
The BZ Series of Horizontal Laminar Flow Hoods meet or exceed ISO 14644-1, Federal Standard 209E for ISO 5 (Class 100) air and IES Recommended Practice for Laminar Flow Clean Air Devices. All units are NRTL listed with MET Labs to comply with UL 1262.

Advanced Control for Biopharmaceutical Aseptic Processes
The full-width work area is continuously bathed with positive pressure ISO 5 (Class 100) laminar flow air that has passed through HEPA filters. These cabinets provide unidirectional, ultra-clean air to enhance sterile product processing. BZ’s are widely used in cGMP-compliant production areas. Our SpillGuard feature is utilized along the sides and back of the unit. The CurveFlex™ forearm support feature provides operator comfort.
