Title: AN NBC FILTRATION SYSTEM WITH BACKUP BELLOWS AND ACTUATION LEVER
Abstract:
A Nuclear Biological Chemical (NBC) filtration system, provided with a manually operated backup bellows and an actuation lever for operation thereof. In an embodiment, the NBC filtration system [10] (Fig.8), comprises: an NBC filter unit [12], a backup bellows [14], an electric blower, and an actuation lever [16]. Manual propulsion of the actuation lever [16] expands and contracts the backup bellows [14]. A grip-able portion [28] of the actuation lever [16] is accessible at a height lower than the installation height of the NBC filtration system. The NBC filtration system may further comprise a transmitting mechanism [80]. Manual propulsion of the actuation lever [16] drives the transmitting mechanism [80] to expand and contract the backup bellows [14]. The transmitting mechanism [80] may utilize the structure of a scissors mechanism.
