Modular Exhaust Filter and Fume Extractor

Improve the air quality around your printer with this Modular Exhaust Extraction System, designed for any 3D printer or laser cutter.

This system combines high-efficiency particulate filtration, activated carbon VOC reduction, and a 4" (100mm) ducting interface that allows you to hook anything up to it.

NOTE: This is designed to work with Modulair lock-ring components and ecosystem to make it even more adaptable and flexible.  

For H2 owners, this works great with my H2 exhaust adapter.

BOM

• 8 - M3x8 SHCS

• 1 - (Optional) EPDM insulation tape (1/8" x 1")

FEATURES

✓ Multi-Stage Filtration
Captures fine airborne particles with a HEPA filtration stage while the activated carbon stage helps reduce odors and volatile organic compounds (VOCs) generated during printing.

✓ Larger Filter Surface Area
Our oversized filter design provides lower airflow restriction than many compact filter solutions, helping maintain strong exhaust performance and more consistent chamber conditions. Unlike other Vento styled exhaust filters, this oversized design helps maintain lower chamber temperatures when printing materials like PLA and PETG, without having to remove the filter.

✓ Modular 4" Exhaust System
Modular attachment system supports standard 4" (100mm) ducting, allowing filtered air to be directed outside your workspace when desired. The duct can be routed to either side, up, or down for whatever you need! Designed specifically to work with Modulair system components for total adaptability.

✓ Serviceable Design
Filters can be replaced without reprinting the entire assembly, helping reduce long-term operating costs.

✓ Designed for Engineering Filaments
Ideal for ABS, ASA, Nylon, PC, PETG, and other materials that generate noticeable odors, fumes, or ultrafine particles during printing.

✓ Engineered for Long-Term Leak Free Designs
This system uses TPU gaskets in every place air can escape from the filtration path. TPU seals better and holds up much longer than other foam tape sealing applications.
