Do you DOP test Vacuums? yes If so, what kind of vacuums do you use? Most vacuums are PowerProducts (use Norclean head) If so, do you use special filters for the vacuum? Most have prefilters and HEPA filters that are purchased through distributors for the vacuums If so, how often do you DOP them? Once per year and/or anytime HEPA filter is replaced What is the failure rate? Relatively low but we do have failures. We have returned some units supplied by other vendors because we could not get them to pass DOP (really PAO) testing. What equipment do use to DOP test with including the smoke generator? We use a TDA-2EN I am not sure what the aerosol generator make model is. Call me if you would like next week and I will run down and get the information off of the device.
