This is a very unique machine, it was designed and built for British Gas, it was designed to evacuate gas pipelines when working on them. It will also pressurize gas to 42 bar. It is also called a recompression unit, and can work up to 100 degrees. It has a Dorman engine which operates the vacuum pump which can vacuum and pressurize. It would be ideal in the oil and gas industry in a third world country. It is mobile, but there is a wheel bearing gone on one of the axles, it is very heavy, about 10 tonnes. We have an instruction manual for the machine. I am sure there would be many applications for this machine
