When dealing with vast amounts of dust, using a pre-separator will capture 90% of the material before it even reaches your dust extractor, preventing premature clogging. Thus, a pre-separator contributes to higher airflow, faster pick-up and extended motor life. You can have confidence in the level of filtration since the pre-separators are equipped with some of the same primary filters used in our dust extractors. Pullman Ermator Pre-Separators Designed to MAXIMIZE Efficiency, Minimize Cost Each Pullman Ermator Pre-Separator works between the floor grinder (or shot blaster, scarifier, saw, milling machine, etc) and the vacuum to catch up to 90% of the dust and debris. Makes You MONEY! * Vacuum Filters stay clean, reducing the need to clean or replace. * Enables you to keep the grinder running all the time, instead of stopping to empty the vacuum and clean the filters (simply turn off the vacuum for a few seconds, let the dust drop into the pre-separator bag, then turn the vacuum back on and get back to work!) * Saves time spent cleaning filters * Saves money spent replacing filters * Keeps your grinder working full time Exact color or shade of unit is not guaranteed. Use Optional lift out plastic bag liners to left out dry dirt.
