A fluid pressure intensifier for producing compressed gas from a low pressure gas source, for an inflatable member of an apparatus for deicing an ice accreting surface comprises: i) an inlet for a low pressure supply of the fluid; ii) a pair of piston chambers, one piston chamber being substantially larger than the other together with small and large piston surfaces associated therewith; iii) conduit means for subjecting the smaller piston chamber to the supply of low pressure fluid; iv) a shuttle poppet; v) an indexer for the shuttle poppet; vi) exhaust conduit means for communicating gaseous fluid from the large piston chamber to a point external to the intensifier, at least a portion of said exhaust conduit means being carried by the shuttle poppet, and a second portion being carried otherwise upon the intensifier, the exhaust conduit portions being alignable by movement of the shuttle poppet; vii) a second source of low pressure fluid configured to be alignable with the portion of the exhaust conduit carried by the shuttle poppet upon movement of the shuttle poppet to a predetermined position; viii) an outlet; ix) a conduit means in fluid transmitting relationship between the outlet and the small piston chamber; and x) a biasing means for biasing the shuttle poppet to and from the predetermined position.
