An aspirator includes an aspirator body having at least one flapper door designed to allow intake of a gas from an environment of the aspirator. The aspirator also includes an aspirator barrel having an end tip, a compressible spring, and a fabric positioned about the compressible spring, and designed to extend in response to receiving the gas and to transfer the gas from the aspirator body to the inflatable flotation device. The aspirator also includes a gas valve designed to receive a fluid from a compressed fluid source. The aspirator also includes a nozzle positioned within the aspirator body, coupled to the gas valve, and designed to receive the fluid via the gas valve and to direct at least a portion of the fluid towards the aspirator barrel such that the at least one flapper door allows the gas to flow from the environment into the aspirator barrel.
