CSE Series

CSE Series: Powder Containment & Powder Weighing Hoods
Germfree’s CSE Series of Compounding Safety Enclosures provide maximum user protection. These Powder Containment & Powder Weighing Hoods protect the operator while weighing and transferring non-sterile powders and compounds. Germfree CSE units provide a main work area with 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. The CSE draws air below the sash opening and up through the filter, washing particulate laden air away from the user.

Germfree’s Powder Safety 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. The CSE is a reliable, low maintenance and cost-effective solution for safely working with powders.

Inward air velocity is measured across the sash of the opening and is set to 50-70 fpm for personnel protection. This velocity range is chosen to minimize air turbulence in the work area. 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. 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, providing environmental protection.
