Topic tags/keywords: question

I built a barrel type separator works good seem to lost a lot of power seal the lid good is there too much volume or is the barrel to bake used a 55 gallon drum tight barrel without the barrel there is twice as much sucking power, use store-bought connectors for the top of the barrel done everything just spec. Use 4 inch PVC for all my runs all joints are tight waist gates on all machines just seems without the separator it works so much better can somebody tell me what my problem is. Thank you very much norm

More info & pictures are needed.

How many HP is the DC?
How long are the runs?
Did you use 90 or 45 degree bends?
How much flex hose is used?
How many tools/machines are used at one time?

Pictures are the MOST helpful, in trying to help you!!!

These things would need to be known, before qualified help can be offered.

Volume of the drum can’t be the problem. Separators introduce a lot of drag (static pressure) to a system, that’s why cyclones usually have larger motors and impellers. In any case, you might check the drum itself for leaks, but if the drum or the lid was leaking, your filters would clog fairly quickly. You didn’t mention what DC you have, but I suspect you may need a little more oomph for your system. Also, 4” pvc will only move about 400 CFM (+/-), so introducing additional drag (the separator) may have been enough to push it to the edge.

Like Fred said, separators cost you power. That doesn’t mean they aren’t worth using. You just have to decide if the trade off is worth it to you.
