Pharmaceutical Laminar Flow Hoods

Horizontal Unidirectional Airflow Cabinets – BZ Series

Germfree BZLaminar Flow Hoods PP
Germfree manufactures Laminar Flow Hoods for a range of biopharmaceutical applications. Our all-welded stainless steel, horizontal clean air benches provide a high degree of localized control for critical aseptic processes and the handling of sterile products. HEPA-filtered air continuously bathes the work deck removing organisms and particulates 0.3 micron in size with an efficiency of 99.99%.

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. They are widely used in cGMP-compliant production areas, USP 797 cleanrooms and 503B facilities. The HEPA filters are positioned in the rear of the work deck and are protected by a removable, perforated metal diffuser.

Compounding Operations for Pharmaceutical Clinical Drug Trials

Germfree’s BZ Series of Clean Air Cabinets provide an efficient platform for preparing non-hazardous Compounded Sterile Preparations (CSPs). Our units are constructed of all-welded stainless steel with a pharmaceutical grade finish to ensure durability and ease of cleaning. 316L stainless steel is available.

Ergonomic Design

Germfree’s Horizontal Laminar Flow Hoods provide optimal lighting with an externally mounted fluorescent light housing. The acrylic top and side panels allow for additional ambient light and maximum visibility. Our SpillGuard feature is utilized along the sides and back of the unit. The CurveFlex™ forearm support feature provides operator comfort.

All-welded stainless steel stands are available with fixed heights for either sitting or standing. Adjustable stands are also available with either manual or electric height adjustments.

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.
