SterilSHIELD®

Pressure Balance Ensures Product Protection

The isolator main chamber pressure is positive to the room, ensuring no room contaminants can enter the work area. Additionally, the main chamber is slightly more positive than the pass-through to maintain aseptic conditions in the main chamber.

• Full ceiling, front-loading HEPA supply filter is 99.99% efficient; provides better than ISO Class 5 (Class 100) air within the pass-through and main working chambers.
• Unidirectional downward airflow purges airborne particulates from the work area.
• A stainless steel air diffuser in the main chamber and passthrough provides unidirectional airflow and protects the HEPA filter.

Plenum Design Optimizes Protection and Extends Filter Life

SterilSHIELD® employs a unique, high-performance airflow system that provides optimum protection from particulates, extends filter life, and reduces the cost of ownership.

• The filter configuration creates internal unidirectional airflow from top to bottom that sweeps particulates from the work area. The filter cross-section covers 100% of the work area.
• The unique plenum apportions and distributes air across, then through the HEPA supply filter, improving downflow uniformity, extending useful filter life, and reducing noise.
• The filter mount provides a direct seal of the filter to the plenum and simplifies filter replacement.

HEPA-Filtered Pass-Through In and Out of the Work Area

• The outer pass-through door is constructed of clear-view shatterproof acrylic plastic and opens with a left-hand swing. (SterilSHIELD 800 has doors on both ends; the left door swings left and the right door swings right.)
• A convenient lift-up sash opens to 8" to permit quick transfer of small items without opening the door.
• The outer door seals against peripheral gaskets to maintain internal positive pressure.
• The internal pass-through door lifts vertically for maximum use of space and permits easy transfer of materials in or out of the positive pressure work area.
