I wanted to post this video on how to make a home made eductor venturi. I have done this for my fish tanks, and included one similar to the one made in this video, in my fume scrubber.

Also, I found these a long time ago, and just found the link again. I have not purchased anything from these people, but I was thinking about it at one time, for a fish tank. Fairly inexpensive.

EDITED: I am building another fume scrubber, I want a more efficient eductor, so I called, and spoke with an engineer at millerplastics about their eductors. With the correct pump, their 2 inch eductor will pull 10 cfm. Its actually a 1.25'' inlet and a 2'' outlet. If anyone would like more information you may message me.

Any comments or corrections, please feel free to post and quote.

The Library threads should not be considered to constitute a complete education. Instead, they're more like reading a single book on the subject of recovery and refining. There is so much more information on the forum, and it is impossible to include it all in these condensed threads. Members are strongly encouraged to read the rest of the forum to round out their education.
