Extractor fan intake funnel 4' diverse funnel size

Ensure the extractor takes air from the front, focuses the extraction where you want it to be and does not curl the air over its body.

Fit by friction!

Built-in guard to protect the fan

For 4' vents (this is a female connector so you may not be able to connect a  4' ventilation hose without stretching it to its limit)

Initially designed for the HZ100 Silent Fan Extractor Duct Hydroponic Inline Exhaust Industrial Vent. However, any duct with an outer diameter of 95.8mm ±1mm will fit well.

There are several dimensions for you to choose from, they vary in size of the rectangular opening. Find one that suits your space and printer.

You may also slice the funnel horizontally to the depth that you need! The print in the picture is sliced from the original file.
