Why can’t I adjust the smoke machine’s output pressure and wouldn’t a smoke machine that generates a higher smoke pressure detect leaks better?
The Big-3 U.S. automakers specified that the design of this technology was to prohibit the user from adjusting the output pressure of the machine (other than for calibration purposes). That requirement was one of many requirements in order to get “OEM EVAP-approved” status on a smoke machine. Not a chance has been taken for the Smoke Wizard operator to make even an honest mistake and over-pressure the volatile EVAP system of a vehicle. Additionally, trying to detect a leak with smoke pressure higher than this machine is set for is actually more difficult. The lower the smoke pressure, the more visible the smoke becomes. To obtain best results when using your Smoke Wizard simply fill the system being tested with smoke; seal system and allow the system to achieve full test pressure; observe flow at the flow meter; inspect system for leaks and adjust smoke flow, if desired. This technique will assure you optimal smoke visibility while providing fast and accurate leak detection!
