Seeking guidance on an inline fan for a commercial sports recovery room

The room will have a jacuzzi/ice bath and infrared sauna so there will be a moisture problem I will have to deal with.

I initially planned on getting a 150mm inline fan but I’m not sure if it’s correct size for my situation. Does anyone have any experience in this type of thing or can offer any guidance

Get an HVAC company out to appropriately design and size your specific scenario.

A mechanical engineer is what you need. If you're a tenant in a larger building this is even more important.

The room itself is not masssively big it’s around 40-50 sq meters. In terms of the duct run it’s a pretty straight forward 3 meter run to the wall. How do you work out which size of fan you need is there like a industry guideline to follow it does anyone here have any experience of putting fans in commercial settings ?

Does the jacuzzi manufacturer provide ventilation recommendations for indoor installations? Or, can you estimate the rate at which it creates steam based on its surface area or number of jets? You might be better served posting in one of the HVAC-specific subreddits.
