Dear Joseph
We use a Ballston 75-60 and it has been in use 8 years attached to a very
oily and wet house air. Some of the purified air goes to our FTIR. It has
been great; no problems. This model has two filters in line and the first
gets the oil and water and gunk and the second is almost always very clean,
maybe a dry powder collected and that is all. My only concern early on was
that our house air is 80-110 psi and this model works best at above 100 psi.
However, it has done its job very well. We change filters about once a
quarter.
Good luck.
