VIVOSUN 8" Inline Fan Carbon Filter, Silver — 772 CFM, RC 412 Charcoal 38mm Bed

VIVOSUN's 8-inch carbon filter pairs a dense RC 412 Australian charcoal bed with a detachable pre-filter to deliver heavy-duty odor and gaseous compound removal for inline fan ventilation systems.

If you need a reliable way to control smells and airborne chemicals in a confined grow space, workshop, kitchen, or basement, this 8" carbon filter is built for high airflow and long service life. The unit uses premium activated charcoal rated 1200+ IAV and a 38mm thick adsorption layer housed in a galvanized steel canister. Designed to mate with 8-inch inline duct fans, the filter balances strong filtration capacity (up to 772 CFM) with features that make installation and maintenance straightforward.

How does this filter remove odors and airborne chemicals?

The core of the system is a thick bed of Australian RC 412 virgin charcoal with very high microporosity for adsorption of odorous molecules and volatile compounds. Air drawn through the filter contacts the charcoal surface, where contaminants are trapped through physical adsorption rather than masking.

• 38mm thick activated charcoal bed for enhanced contact time
• RC 412 Australian virgin charcoal rated 1200+ IAV for strong adsorption
• Dual-sided galvanized steel mesh increases open area for efficient flow

Will it handle high airflow without restricting my fan?

This filter is engineered to support robust airflow: the round-hole galvanized mesh and extended canister design increase the open area and minimize pressure drop at higher CFM. That makes it suitable for inline fans sized to 772 CFM or lower while preserving filtration efficiency.

• Max airflow rating: 772 CFM with minimized restriction
• Lengthened canister maximizes the effective filtration surface
• Reversible flange aids in optimizing flow direction and service life

How easy is maintenance and installation in a grow tent setup?

The filter includes a detachable pre-filter cloth that captures about 99% of larger particles, keeping the activated charcoal cleaner for longer. Assembly is tool-friendly: the reversible heavy-duty flange and included mounting belts let you install the filter as intake or exhaust, and you can flip the canister orientation to extend usable life.

• Detachable pre-filter blocks 99% of particles to protect the charcoal
• Reversible iron flange and base for flexible mounting positions
• Includes a pair of belts for quick tent attachment

What environments and applications is this filter best suited for?

While optimized for indoor horticulture, the filter works wherever concentrated odors or gaseous compounds need mitigation. It fits 8-inch inline fan systems in grow tents, hydroponic rooms, kitchens, basements, and small workshops, delivering consistent odor control without bulky ductwork changes.

• Ideal for grow tents and hydroponic rooms needing tight odor control
• Suitable for kitchens, basements, and small workshops with chemical smells
• Compatible with standard 8-inch inline duct fans for intake or exhaust

Who is this for: This VIVOSUN 8" carbon filter is aimed at growers, hobbyists, and homeowners who require robust odor and gas filtration in confined spaces. Choose this model if you need a high-capacity charcoal cartridge with easy mounting, a protective pre-filter to extend service life, and compatibility with 8-inch inline fans. It’s a practical option when you want reliable adsorption performance without frequent replacement or complicated installation.
