Filtering with a Negative Pressure Setup

I hate for my first post to be in the steroid section but I was wondering if anyone has anyexperience filtering homebrew with a negative preassure set-up (pumps). Whats needed? I have plenty of experience with the standard syringe and whatman filters, but am going to be compounding a bit more test-e than I would like to sit around and push through that way.

Any Help is appreciated…Links to how to use the equipment would be amazing.
