The MSDS sheet as seen in this link
http://media.photobucket.com/user/Euclid_bucket/media/22017lg.jpg.html?filters[term]=santa&filters[primary]=images&filters[featured_media]=1341&sort=1&o=85 also states used engine oil vapours to be flamable. I had long waited to build a similar device that you made but my vacuum pump is only rated for general purpose air not flamable vapours I don't see any way to dismiss the dangers unless the pump is up to snuff.

... so, in reverse, putting the OIL in a vacuum will separate the LIQUID into a VAPOR...

Then just add a length of tubing to allow the exhaust from the vacuum with the flammable vapor laden air a distance from the non explosion proof motor and electrical connections. He may have it i will replay the video to see how it exhausts.

Freeze his video at about 0.04 there is tubing from the exhaust side of the vacuum pump. If someone wants to be a little safer and a foot or so. That should allow the vapors to drop below the lower explosive levels even for heavily gas diluted motor oil. It also appears to be outside, if doing it in side of a garage let the exhaust tubing discharge under the closed door to the outside atmosphere.

If 570- 70 = 500F is the motor oil's boiling point in the tank under 25" HG, that means the oil remain as a liquid and not change to vapor. An explosion requires a flammable substance + oxygen in a confined space. Even if there is a flammable substance in the tank, there is no oxygen since it is under vacuum and the oxygen has been evacuated, an explosion cannot occur inside the tank. Outside the tank, there is oxygen, but there is no confined space. Even if there is a flammable substance (which there isn't), an explosion cannot occur. It will simply burn (like a torch), if somehow it got ignited. You are worrying about nothing.

if you are considered about oil vapor in this tank exploding then how come your engine does not explode from it if the vent tube gets a bit clogged - the blow by contains a fair amount of oil vapor.

Where in the tank would be the ignition source ?? Oil flow sure wont provide it !!

Leave him alone guys. There is no harm in warnings on the Internet.

All you have to do is just ask yourself every time you go to change your oil would it be ok it put an open flame on the intake of the vacuum tank. If you answered no then why take the chance with a pump that is not rated for the application. The point of ignition during a drawdown would be at the DC motors contacts then travel to greater concentrations and naturally be sucked into that tank.
Bang that's my take from experience.

Leave him alone? Are we allowed to ask him questions?
