I have been using this dust containment system for over 10 years. It was an expensive addition to my tools but well worth it. No other sanding companies in there area use this. Why not?
Because it is expensive and adds time to the sanding process because of set up and working around the hoses connected to the equipment.
Well I choose to use it because I don't have tons of dust flying around your house and getting in my lungs or ending up in the final finish.
It is amazing how much cleaner the entire sanding process is using this and it shows in the final product!
