For efficient transfer of Butane, Propane or Anhydrous Ammonia
Tank Evacuation Vapor Compressor
The Krug compressor transfers liquid by increasing vapor pressure in teh tank being emptied, and decreasing vapor pressure on the tank being filled. A separate hose transfers the free flowing liquid.
NOTE: Check the compressor crankcase oil before each use. The compressor requires 5/8 of a pint of SAE 40 oil, 1″ on the dipstick. Low or no oil may damage the compressor.
