Started tearing out tile to do stained concrete. I have two DeWalt DWV012 vacs, a big 7" grinder, DeWalt 7" dust shroud and a 7" cup wheel. My vacs can't not keep up with the grinder and DUST EXPLOSION. Better than no vac, but I wouldn't even say it's catching more than 60%. Brand new filters, fleece bags, paper bags, it doesn't matter.
I am strongly entertaining the idea of making a dust separator for a 30 gallon trash can to help with the need for changing out filters and emptying bags but I'm wondering if there is anyone that has done anything like connecting vacs in parallel (or in series) not sure of the terminology I want for this.
Would putting a simple Y on the vac side be the best option? I definitely need to maximize airflow and suction without the two vacuums fighting each other.
Any ideas or recommendations?
