I run my own body shop in my garage. I don't have the money yet to afford to invest in a large general purpose air conditioner. I can use it to extract freon from any car. The recovery time is the same as any machine I've used while working at a large department store. It's not loud. And pull a little vacuum when all the freon is pulled out. Use this machine on a vehicle with vehicle sensors. You will need to purchase hoses and adapters to convert it to the threads used in automotive gauges. Conventional air conditioning pressure gauges have a different threaded connection. The flushing function is also to empty or clean the hoses of freon, which is important when changing from one type of refrigerant to another. This will not remove air from the recovery tank.
