Balance Enclosures

Germfree’s CSE Series of Compounding Safety Enclosures and Powder Containment & Powder Weighing Hoods protect the operator while weighing and transferring non-sterile powders and compounds. The Balance Enclosure consists of a main work area with one (CSES) or two (CSED) large hinged windows for the easy ingress and egress of large equipment. Pre-filters are located above the work area and swing down for easy replacement. The pre-filters aid in extending the life of the HEPA filter by removing large particles.

Performance Data
Inward air velocity is measured across the sash of the opening and is set to 50-70 fpm for personal protection. This velocity range is chosen to minimize turbulence in the air. The airflow pattern passes directly through the unit with a constant wash of air across the workdeck. The inward face velocity meets all requirements for a Class I Biological Safety Cabinet as defined in the CDC-NIH BMBL 5th Edition. The exhaust air is vented into the room after HEPA filtration, providing environmental protection.

All exhausted air is HEPA filtered removing particulates at an efficiency of 99.99% for 0.3 micron particle size and is vented into the room.

The CSE powder containment/powder weighing hoods draw air in over the sash opening, then up through the filters, providing a wash of particulate laden air away from the user. All CSE Powder Balance Enclosures are constructed from high quality stainless steel and acrylic. The stainless steel surfaces inside the hood are impervious to most chemicals and are easily cleaned. All CSE models provide a safe, dependable and lower cost environment for your facility.
