The UltiMaker Recirculation Module Left is an OEM spare part for the UltiMaker F Series (Factor 4) industrial 3D printer. It is the left-side unit of the active air recirculation and filtration system integrated into the Factor 4, which captures volatile organic compounds (VOCs) and ultrafine particles generated during high-temperature printing of engineering-grade materials.

The Factor 4 active filtration system is a key feature for safe operation in professional environments, particularly when printing materials such as ABS, ASA, PA-CF or other compounds that emit VOCs at processing temperatures. The recirculation modules draw air from within the build chamber, pass it through filtration media, and return cleaned air to the enclosure. Replacing a worn left module with a genuine UltiMaker part restores full filtration capacity on that side and maintains a safe, compliant working environment.

Key features

• OEM left-side recirculation module designed for the active air filtration system of the UltiMaker Factor 4.
• Captures VOCs and ultrafine particles emitted during high-temperature printing of engineering-grade filaments.
• Recirculates filtered air within the build chamber to maintain both air quality and chamber temperature stability.
• Direct OEM replacement ensures correct fit and airflow characteristics to match the right-side module.
• The matching Right Recirculation Module (article 210000006011) is available separately to complete or restore the full filtration system.
