Inlet size for spray booth

[andeep]

Hi there,

Need someone to help me on calculating the inlet size for my DIY spraybooth.

The booth is around 26 cubic meters and the extractor fan is 315mm with a 1165cfm.

What size inlet (with filter) will I need for proper airflow?

if the fans 315mm a 12 inch duct will do, just make a larger box on the end for the filter
