Hi everyone,
Guys at my work, and I, of course, are using 3M Adflo. All air blowers look same (all same part numbers 35-1099-01 in North America), until we open them to change filters. We notice they have slightly different marks on top left corners (you can see from the photos). We’ve got no idea what they mean.
Most of us bought them pre-owned and don’t have much papers with them to look for more info. It’ll be great to know why they are marked like that.
Thanks.
*** Notes: at top left corners of the blowers we found no mark, one white dot, one yellow/amber dot, two white dots, or two yellow/amber dots
