Some Diffusion pump Questions
Re: Some Diffusion pump Questions
You can also get an oil mist eliminator. But ones that completely get rid of the mist are expensive and bulky. There's an faq on this subject.

Re: Some Diffusion pump Questions
Virtually no one does not vent their roughing pumps into the rooms. You can get mist filters or make them. Simplest is getting a truck oil filter and putting a pipe nipple in the center thread where it screws on. Connect this to your exhaust. This works very well, better than some commercial filters I have used.
With a load lock you are not going to be pumping a large volume of air so you will not create much mist.
For basic testing you should be able to just use one pump and tee it off to the load lock and the DP. Save money. There is a very high possibility that this thing will never work and I have seen SEMs working with everything go for only a couple grand around here.
