The product is sold as a complete set, and the blower model is fixed. It is recommended that you can replace it yourself.

We recommend this one for you: https://www.vevor.com/inflatable-paint-booth-c_10313/vevor-inflatable-paint-booth-23-x-13-1-x-9-ft-inflatable-spray-booth-with-750w-480w-powerful-blowers-and-air-filter-system-portable-car-paint-booth-for-small-truck-large-motorcycle-midsize-suv-p_010696680503

This product does not have any additional interfaces and cannot be fitted with an exhaust fan. You could consider using an exhaust fan by unplugging the fan duct from the zipper.

I did not find any information about replacement parts in the product description or customer reviews.

According to the product description, it is equipped with primary and activated carbon filters that block dust, dirt, remove odors and harmful gases. However, customers did not find the filters very effective in removing strong paint fumes.
