Mobile single-stage wood dust collectors direct large and small sawdust particles to the bottom bag while filtering air through a felt bag. Felt filter bags can be cleaned and reused as needed. Mobile dust collectors are wheeled to move around a shop to the point of collection.

Mobile single-stage wood dust collectors with a cartridge filter capture smaller particles than standard, bag-style dust collectors. Pleated cartridge-style filters have more surface area than felt bags to improve airflow. They're also cleaner and remove smaller particles than felt bag-style filters. Mobile wood dust collectors can be wheeled around a shop to access tools.

Portable two-stage wood dust collectors direct larger sawdust particles to a collection bag while directing air and small particles to be filtered through a felt filter bag. Filter bags are made of felt and can be cleaned and reused as needed. Portable dust collectors can be moved around a shop or taken to worksites. They're lighter and have a smaller capacity than mobile dust collectors.
