A quick note on these Chinese evap testers. They put out way to much pressure for evap testing. The maximum pressure for the evap system is .5 psi or around 13.0 in. H20. The Ancel is putting out way over .5 psi. Anything over 7 psi can damage pressure sensors and or blow off hoses. 14 psi is OK for intake and exhaust testing but way to high for evap.
Hello Mike. Thanks for your comment. I've used my Ancel S300 smoke machine for vacuum, crankcase and even internal coolant leaks and I've been very happy with it. I would prefer to follow manufacturer recommendations and use an inert gas for evaporative testing and that can't be done with most inexpensive smoke machines that use an internal compressor.
