DFHP (H2O2) PASS BOX
A non-conventional breakthrough in the field of FHP systems. This equipment implements the latest dry fog technology provided by high-tech nozzles in conventional FHP systems. The proven advantage of this system provides:
- Total cycle time reduced to 2 hours (7-9 hours with older methods).
- Cost-effective.
- Fully integrated and automatic process.
- Easy validation.
- Produces 7.5-micron fog, which does not wet the surface and avoids corrosion.
- Dry fog covers inaccessible areas, reaches through crack crevices.
- Biodegradable Sterilant used achieves 6 log reductions of bacterial spores in just 1 hour contact time.
- Concentration of H2O2 reduced to 2%, as compared to 32% in traditional FHP systems.
In addition, the downward flow of HEPA-filtered air provides protection by minimizing the chance of cross-contamination along the work surface of the FHP Pass Box.
