That one is loud, cheap, and won't last long.

Dang I keep forgetting about this. Sounds like for on the go CFing you would want a closed top along with maintaining a constant vacuume level to suck out water vapor as it is expelled from the CF.
Would that work?

Vac the barrel probably wouldn't work very well since the vapor could condense on the metal walls before getting vacuumed out. A cross fitting in the line right below the CF with a fan blowing air across would be better. Fans are cheaper and simpler. And then your vacuum pump oil doesn't keep getting contaminated by water.
If so; is there a way to measure vacuum with some sort of switch thus giving you the ability to keep the amount of vacuum constant?

If it helps at all maybe have the CF mounted inside a small tank with a bit of vacuum on it to suck out the water vapor while the dry oil drains on back into the tank from which it came.?

I prefer the way I have mine setup, I can use the same rig open top for dewatering and while at home, and then put on the lid closed top for running down the road, then open it when I am stopped somewhere to get the dewatering done (its usually dewatered much faster than the particle removal.)

Have you used your mobile genset powered CF rig much Sun?

I'm betting you likely use your stationary unit more, but I just wanted to see how well your mobile rig has performed for you over time.

Would you trust it for your sole source of CF cleaned WVO?


I don't mean to batter you with seemingly stupid questions, but since I live in a condo, my options are currently a little limited.

If I build a mobile CF rig and buy a genset to run it, I want to know that I can rely on it 100%. If that's unreasonably optomistic, then I'm better off finding a location for a stationary CF unit.

No I haven't used it much mobile, but its the exact same rig I use at home, so yes I trust it for all my VO and have been using it for ~2 years now.
