I thought I'll get myself a christmas present and here it is. I love the military items on ebay, this is NOS item the eletric motor will be here next week just need to do a bit of work on it and she ready to fill scuba tanks, Which will be use for air impingement starting my turbine engine projects. As i live in the grey head nanny state of Australia i ask some local scuba diving shops if i can get a scuba tank refill they all said i have to be a certified diver to get a scuba tank refilled. So i say F#$%& em all this is why i decided to get one of these compressors.

Hi Chris, Your right there mate when i got a compressed air bottle for testing the JFS it cost me $100 for a bottle plus rent and maintenance fees WTF! this is from industrial gas supplies who think they are GOD. The compressor looks well built, i was told these were made back in the 60s. There are some on ebay at the moment 251402129756 161186023267 230736060137 LOL i don't know what the burst pressure for a scuba tank is?

Hi all, I finally got this compressor up and runing not happy with it as it took 40 mins to get 1,000 PSI air pressure in the tank. I did notice a leak where the condensation drain valve is so will get that fix and also check the rpm as this compressor should take ~25 mins to fill a scuba tank. youtu.be/VhqJY1ZXHJo?list=UUhmWRMa7r3wD3OV7m0I_eOQ

Hi John, I decided to by pass the chemical dryer chamber and this has made a big impovement, it took ~14 mins to fill the last 1,000 PSI air pressure in the tank so very happy now :-))))) The filter in the chamber was halfway through its life as you can see in the photos when that strip goes to a tan clour it's finish and will take longer to fill a scuba tank and i don't think i need to dry the air as i wont be breahing the air. secound vid youtu.be/SSefoD_NJ-k
