I have a Robinair model 15310 vacuum pump that I use for stabilizing. I'm tired of filling up my shop with exhaust from the exhaust fitting. I've seen some filters that seemed like they might work but when I asked the tech's if it will work on my pump all they can tell me is the proper adapter to use, maybe. One even suggested attaching a garden hose to the exhaust fitting and directing the exhaust outside the shop. Great in good weather but come on, I live in Montana, that would exclude from October to early May. Does anyone have a system they use or who can direct me to a company that can fill this need? I'm more than frustrated and hoping someone here will have the answer. Thanks in advance.
