AC Infinity Refillable Carbon Filter Kit, with charcoal refill, 100 mm

Product detailed description

Replace only the carbon, not the whole filter

AC-RCF4 is a refillable carbon filter for duct ventilation with a diameter of 100 mm (4"). Its patented design allows the filter to be refilled repeatedly with new activated carbon instead of replacing the whole filter with a new one. It is intended for compact 100 mm ventilation systems - smaller grow tents and mini setups.

Package contents: body, refill, funnel and scoop

The package contains an empty refillable filter body and also 1+ replacement activated carbon refill - together you get a capacity equivalent to roughly two standard 4" filters. The package also includes a funnel and a scoop for easy filling without mess.

How the filter opens and is filled

The aluminium flange can be detached without tools (twist-off) and is also reversible. New carbon is poured in using the included funnel and scoop, and the rubber seal then keeps the joint airtight.

RC412 carbon inside the mesh

The RC412 activated carbon comes from Australia (virgin material), quality 1200+ IAV, 38 mm thick layer. The carbon is retained by a double-layer galvanised steel mesh with a sandblasted gunmetal finish, resistant to corrosion.
