I have a 4x8 prt in my school district. I have always wanted to put a vac table on it but up to this point have not been able to make it happen.
I have mostly looked at the dual vac motor option that Brady came up with forever ago. However, recently I have gained access to a surplus Leybold WSU501 blower. http://www.pchemlabs.com/product.asp?pid=3966 for specs.
Knowing basically nothing about the actual air flow and pressure requirements of what is needed and what would be too much I have no idea if this blower would work for me or not. I just know it might have potential and I can get it for cheap.
I would appreciate any feedback that those of you who have designed systems could share with me.
P.S. The 3 Phase is not a problem.
