Equivalent to the compressor on an air brake system. Performs the same function as the ejector on a steam locomotive. Exhausters are usually designed to run at two speeds - slow speed to maintain the vacuum against small leaks and losses along the brake pipe and high speed to get brakes released after they have been applied.
