SigilVentus 4" x 16" Carbon Filter – 350 CFM Inline Odor Scrubber for Hydroponic Grow Tents

Reliable Mid-Sized Filter for Tight Indoor Spaces
Designed for growers who need stronger odor protection without increasing fan size, SigilVentus VENTUS-0416S handles up to 350 CFM. Its extended body improves filtration time, making it ideal for mid-sized tents and stealthy grow cabinets.

Enhanced RC-48 Charcoal Filtration
With 3.8kg of machine-packed RC-48 carbon in a 45mm thick bed, it captures VOCs, terpenes, and strong plant odors with ease. The increased surface area ensures a longer filter life and consistent airflow.

Built Tough for Grow Environments
The housing is made of anti-corrosion cold rolled steel with a wide perforated shell. It resists rust, wear, and high humidity. A Velcro pre-filter is included to trap larger particles.

For Tents, Dry Rooms & Micro-Grows
Perfect for 3x3 to 4x4 grow tents, drying setups, poultry hutches, or indoor garden closets. Matches best with 4” EC inline fans.
