In a further controversy, the alleged gas exhauster machinery and mysterious massive ventilators that might have been used to remove the gas into the atmosphere following the gassings were removed and scrapped during renovation works in 1996 and the early 2000s.

At this point, it enters the exhauster house and passes through an " exhauster ", an air pump which maintains the hydraulic mains and, consequently, the retorts at a negative pressure ( with a zero pressure being atmospheric ).

The combination of the arc heater driver, various nozzle / throat combinations, the evacuated test cell, and exhauster makes possible high-enthalpy flows at Mach numbers from 5 to 9 . Direction and distribution of the injected air can be selected to optimize the enthalpy distribution across the flow to match specific test requirements.

They are made up of an in-line arrangement ( from left to right ) of an 8, 000 horsepower steam turbine, then two low-pressure compressors, a high-pressure exhauster, a 27MW 11kV synchronous motor that provided 36, 000 horsepower, and finally the barring gear and the exciter ( a small generator that provides a current needed to start the main motor ).
