Can-Filter Flange – 14 in

The Can-Filter Flange – 14 in is a spun steel fitting designed to connect a Can-Filter carbon filter to a duct run or a Can-Fan inline fan. It ships with a foam rubber seal and six hex drive self-tapping screws, forming a tight, airtight connection at the filter outlet. If you are running a 14-inch duct system in a large grow room or commercial space, this is the matching flange for that diameter.

Why Choose the Can-Filter Flange – 14 in

This flange is the purpose-built interface between Can-Filter carbon filters and the rest of a ventilation system. A few reasons growers reach for the Can-Filter brand flange rather than a generic alternative:

• Exact-fit engineering: Can-Filter flanges are sized and manufactured to match the outlet threads and shoulders of Can-Filter carbon filters. A generic spun-steel fitting may seat loosely or require extra tape and effort to seal correctly. The Can-Filter flange seats cleanly without guesswork.
• Complete hardware in the box: The flange ships with a foam rubber seal and six hex drive self-tapping screws. You do not need to source a separate gasket or hardware kit to make the connection airtight.
• Spun-steel construction: The flange body is formed from spun steel, which handles the mechanical stress of ducting tension and the weight of a can-style filter without deforming over time.
• Wide size range: Can-Filter produces this same flange design in diameters from 4 in to 20 in. If you are scaling up or running multiple duct runs of different diameters, the same brand and hardware pattern applies across the range.
• Straightforward installation: The six included screws drive directly into the filter housing with a standard hex key. No specialized tools are required beyond a hex driver and basic duct tape or clamps for the duct connection.

Best Uses for the Can-Filter Flange – 14 in

The 14-inch diameter is suited to high-volume ventilation systems where large duct runs are necessary. Typical applications include:

• Large commercial grow rooms: Rooms requiring 2,000–4,000+ CFM of exhaust airflow typically use 14-inch or larger ductwork. The flange bridges the carbon filter to the main duct trunk at this diameter.
• Connecting a Can-Filter to a Can-Fan: The flange was specifically designed for this pairing. When mounting a Can-Filter directly to a Can-Fan (fan-on-filter configuration), the flange provides the mechanical and airtight interface between the two units.
• Replacing a worn or damaged flange: Over time, foam seals compress and steel flanges can corrode in high-humidity environments. This flange is a direct replacement for any Can-Filter installation running 14-inch ductwork.
• Exhaust-side duct transitions: The flange is positioned at the airflow-out side of the filter. If your duct layout requires a transition from a 14-inch opening at the filter to a flex or rigid duct run, this fitting is the starting point for that connection.
• Multi-filter commercial installations: In facilities running several large carbon filters in parallel, having matching flanges across all units simplifies future maintenance — all fittings use the same screw pattern and seal size.

If your system uses pre-filters on the air intake side, see the Air Box 4 pre-filter for an intake filtration option designed for larger grow room setups.

Compatibility

The Can-Filter Flange – 14 in is designed for use with Can-Filter carbon filters across their full product range. It connects the filter to standard 14-inch flexible or rigid ducting and to 14-inch Can-Fan inline fans.

Before purchasing, confirm your filter’s outlet port is 14 inches. Can-Filter carbon filters are available in multiple flange sizes — the same filter body can ship with a 6-inch, 8-inch, 10-inch, or larger flange collar depending on the model. Match the flange diameter to your existing filter outlet and duct diameter.

The flange works with any 14-inch round duct, including standard HVAC flexible duct, spiral rigid duct, and Can-Fan inline fans rated for 14-inch connections. Standard hose clamps or foil tape can be used to secure the duct to the outer edge of the flange once the flange itself is screwed to the filter.

For growers pairing this with an inline fan, the Active Air HD pedestal fan provides supplemental air circulation within the grow space, working alongside the exhaust system rather than replacing it.
