Allegro filters and pre-filters are offered in six different combinations and allow maximum flexibility for varying work applications (including HEPA for Hexavalent Chromium control and 95% for carbon steel weld fumes). All filters are made in the USA.
Use this filter as an alternative to the standard pleated pre-filter (9450-PF) and is used for general dust and dirt capture as well as for reducing or eliminating odors from the welding process. Replacing this filter as indicated by the extractors filter status light will help ensure maximum life of the main and HEPA filter.
