Wilco Original carbon filters

Choose your Wilco Original carbon filter by capacity and flange size. Our range has five models, from 500 to 2500 m³/h, with connections from 125 to 250 mm. Also check your extractor fan, mounting space and duct run. We can help you put together a suitable combination.

Which Wilco Original suits your extraction setup?

Start with the airflow your installation needs, then check the flange size. Wilco Original offers five combinations. The 200 mm connection is available with both 1500 and 2000 m³/h, so matching diameters do not mean matching filter capacities.

Choose the filter together with your duct fan and complete duct run. Stated filter capacity is not a measured airflow in your grow tent. Duct length, bends and the filter itself add resistance.

Allow space for the filter body, connection and mounting hardware. The photograph shows the filter family and is not a scale comparison of the five models. Check the selected model before ordering.

Plan the duct run around your connections

Record the diameters of your filter, fan and ducting. The smallest Original has a 125 mm flange; the 1000 m³/h model uses 160 mm. Both the 1500 and 2000 m³/h models use 200 mm, while the 2500 m³/h model connects to 250 mm ducting.

Prefer a straightforward run with suitable connection sizes. A reducer changes the connection, but does not increase filter capacity. Our guide to duct diameter and length helps you plan the joints.

Check mounting and the pre-filter

Provide secure support and access for inspection and maintenance. Do not leave the filter weight hanging from the ducting. Check joints for leaks and keep the air path free from kinks and compressed sections.

A pre-filter sleeve catches dust; it does not replace the activated carbon. Check it regularly for dirt. Our guide to fitting ducting to a flange explains how to choose a clamp and seal the joint.
