Used air compressor pump. Been sitting in my garage for many years. It is a two stage, four cylinder pump. The overall height is about 28″ and the four sheave pulley is 16″ in diameter. It spins over like it should, but that is about all I know about it. I have not weighed compressor, but would guess around 200 pounds. Please contact me with any questions you may have.
