If so, how much air does it consume?** A: Yes should be connected to an air compressor. The pressure range is specified in the manual that I don't remember the exact number, but my small compressor worked just fine. **Q: This being a german tool, is the quick coupler a na version or european?** A: I gobbled one together to allow it to work, but no longer have the vehicle. If anyone needs the wand with a connector that allows yo to get from Swedish to USA standard fittings, I can help. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Perfect for a/c cleaning *by O***V on July 21, 2022* Highly recommend getting this one for a/c cleaning ### ⭐ Don't waist your time *by A***O on January 26, 2026* Sent product back because it is almost impossible to get the disinfectant solution to use with this gun after several attempts.
