Prevents Fine Dusts from Clogging Your Vacuum's Filter!

The only thing more aggravating and time consuming than removing fine dusts like concrete, is unclogging the filter you cleaned it with. The dust gets everywhere and sticks to everything (including your lungs!). The CDD Pre-Separator protects your vacuum filter from even the toughest dusts, including: concrete, silica, metal debris, soda blasting, and more!

With the CDD Pre-Separator connected to your dust extractor, you'll save countless time and money on replacement parts and downtime for maintenance as you virtually eliminate filter clogging and suction loss! Our patented cyclone also helps contractors and construction crews become compliant to the new OSHA Silica Dust Safety Standard, especially when used with tools such as handheld grinders that specifically requires a cyclone separator.
