We apologize for the late response.
Because it took time to look up a suitable blower fan to recommend.
The new version of our OPERA-06 spray booth is compatible with most products with a 150mm (6 inch) exhaust pipe FAN.
FANs of this spec can be easily compared and purchased at a wide variety of price ranges at shopping malls such as amazon.com.
In addition to the products in the URL attached above, you can use any number of higher performance products or cheaper products if you wish.
If you have any question, please feel free contact to us.
Thank you :)
