The TM-SV include a G4 dust filter, an activated carbon odor filter, and a filter for NBC (Nuclear, Biological, and Chemical Contamination Protection). To prevent contamination of these filters when there is no danger, the damper can be placed in the reverse position, allowing air to pass only through the G4 Dust Filter. TM-SV model is equipped with a manual drive lever for use in case of a power outage. This lever allows for ventilation to be provided even in small shelters.
