摘要：
A manually actuated backup bellows for Nuclear Biological Chemical (NBC) filtration systems, which is ready for immediate manual actuation in case of electric power failure. The backup bellows (Fig. 3) comprising: a deformable portion [22], a first closure [24] trimming a first end of the deformable portion, a second closure [26] trimming a second end of the deformable portion, at least one inlet port [28] fitted with an inlet one-way valve [30], and at least one outlet port [32] fitted with an outlet one-way valve [34]. Manual back and forth actuation of one of the first closure [24] or second closure [26] in relation to the other, expands and contracts the deformable portion [22]. According to an embodiment, the backup bellows further comprises an electric blower [36] fitted to an internal space of the backup bellows. The electric blower [36] is mounted to one of the inlet port [28] or outlet port. As a result, the backup bellows and the electric blower can be operated alternately, independently of each other.
