whats the highest cfm/water lift/gpm extraction in a portable that can be get for under $3k new or used and the cheaper the better and extraction is all that's needed but it has to be auto dump
Yes thank you, one thing i know nothing is as easy/simple as it seams therefore i am here asking million questions not just buying big numbers - thank you all for all advices/infoRemember the bowling ball trick shown on tv; lift can only account for so much water extraction. Without the off setting cfm with that much lift; extraction can stagnate. It is more efficient to have adequate lift; and off set by high cfm than vice versus.
Ever see an air show(Blue Angels or Thunder Birds); Notice the pictures where the vortex vapor is super heated prior to aircraft exceeding the sonic barrier. High air flow at the entry to the air inlet of the engines causes this.
Just as a t/m; high cfm to low/medium lift is what gives them their powerful extraction rates. In your hunt for adequate lift; shop for cfm's. I can appreciate your position; but remember, porties with 1.5 inch plumbing and hoses limit your lift and cfm; as well as length you can run the hose to a job.
I hope this was helpful.
