Need More Suction on the extraction

Evening all

I have finished my cnc build and have been up and running/learning for the last few months. My biggest problems is the extraction will extract dust but not small chips. Its a Draper tin design 3.05 m3 min or 50 litres sec. I'm limited to space. appreciate any ideas or recommendations / upgrades.

Thanks Adam

This any use ?

Is the fan motor 1 ph or 3 ph

Thanks Eddy ill have a look.

Hi John. only single phase.

Thanks Both

I asked because I have used an inverter in the past to increase the flow, even a small increase in frequency works wonders.
