EVAP Smoke Tester without Air Compressor UK
Answer first: An EVAP smoke tester without air compressor UK mobile techs want is a 12V unit with its own pump and adjustable low pressure—not a bay-only smoke gun on shop air.
Driveway EVAP jobs fail when you cannot bring an air line. Built-in compressors change that workflow.
