Vacuuming MDF

Post by mristau » Wed Aug 05, 2015 4:28 pm

Have problem with MDF dust clogging my vacuum bag/filter, overworking, overheating and shutting down when leveling my table. Is this a common problem with MDF? If so, what's a fix?

There's some other things on that page which you may find of interest.

Vacuuming MDF

Post by Jimf » Wed Aug 05, 2015 5:46 pm

I like the dust deputy. I have two of them. One for my CNC and the other is in my woodshop. I've emptied the buckets many times and still havent cleaned the filter or emptied the vac. I cut plenty of mdf too. I did make a Thein before I bought the 2nd dust deputy. I don't think works as good.

I also put a paper filter bag in the shopvac. That way no dust gets trapped in the filter. The paper bags were fairly cheap at Home Depot.

Winston Moy made his own dust separator using an S3:

Probably not useful for MDF but for plastic like glass filled polyester and printed circuit boards and similar materials that generate hazardous dust, I built a water filtration system.

Two Homer buckets and a Bucket Head shop from Home Depot vac, a bunch of PVC pipe and several hours of milling. Voila, no dust at all in the shop vac.

I bought a Dust Deputy a while back. I love it. Works great and keeps the MDF dust out of the filter.

A Dust Deputy may work great for large particles but, for me at least, it didn't even begin to catch the very fine dust from a PCB burr.
