Hello from Scotland,
I'm a newbie to lasers and have just received my Chinese Voiern 9060 80W laser (my retirement present to myself after 30 years in the Fire and Rescue Service).
My initial idea was to purchase a small desk top size Chinese laser to use in cutting out model aircraft parts (wing ribs, bulkheads etc.) but after watching Russ's laser tutorials i realised the many other uses a laser provides, so opted for a size that i could 'future proof' and use for other things.
I have encountered a problem with the 'bouncy castle' type fan provided with the laser in that it leaks around the outlet flange. I have temporarily stemmed the leak using epoxy resin and silicon sealant but wonder if anyone can recommend a more robust and powerful extractor fan as i don't want to inadvertently poison myself. I have fitted a Carbon Monoxide and smoke detector in my workshop as a precaution.
Kind Regards,
Kenny.

Welcome Kenny- don't know what bouncy castles use for inflation [my Kids predated those]- is it a tall squirrel cage blower with 4" inlet and outlet? These are generally adequate - sounds like the exhaust may be restricted? Gene

Not sure what fan comes with your larger one but I have done a fair few mods to my smaller Vollerun as far as 'fixing' the Airflow across the bed and sealing the cutting area and fan.
Take us a picture or two as there is nothing on Aliexpress or their website that shows the fan or duct for yours.
Assuming yours is built in a similar fashion to mine block the speed holes to improve where the fan is drawing air across the bed Cloth tape would work too

Next job was to get the Laser drawing from front to back into the fan. This is a bit rambly but it starts here with an inlet duct across the full width of the bed at the front of the Laser viewtopic.php?f=111&t=3901&p=21898#p21898
The actual fan on mine will be a lot smaller than yours (I hope) but I used some silicone R/C fuel tube as part of my fix and made an 3D printed adapter between the Laser body and fan.
