The Munktel HEPA-filter is used in our bio-clean operating room. The filter pannel sized 2.6m×3.6m is composed with twenty HEPA-filters.
In order to improve hoirzontal laminar flow, three return grills are furnished on the opposite wall and two sliding walls are set in bilateral sides.
The HEPA-filter works in three different steps as following manner. In the low step two HEPA-filters are work, in the medium step nine filters, and in the high step twenty filters. In the high step working condition, ventilation of the room is increased to 240 times per hour and the class 100 of bio-clean air is accomplished within only five minutes.
