Allegro Industries 9450-AM Specialty Aluminum Mesh Oil Pre-Filter for Portable Fume Extractor

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.

This pre-filter is used as an alternative to the standard pleated pre-filter (9450-PF) and is used to capture oil mist present in some weld applications. Cleaning this filter after each use will help ensure maximum life of the main or HEPA filter.
