Are these Axial or Centrifugal Liverpool fans and which one would be best for my outside netty. Does it need to be wired in SWA or bellwire?? Does it need a fused spur, RCD and Earth Rod??? And what about the cast iron cistern and brass chain. Do they need to be bonded??

Please help this poorly retired plumber to vent the stink from his netty.
