We used to use HF air tools for final assembly of projects before painting. They were NEVER oiled and had short life spans but this was the planned procedure to keep any oil or other contaminants out of the painting area. Now use all battery powered tools. The HF pneumatic paint can shaker must be at least five years old and still plugging away. Some HF do the job and some are trash can fodder but don't have a list of each. Caveat Emptor.
