I am in the process of building a sand blasting cabinet, but have been having issues with the abrasives getting sucked into the extraction fan.
The fan is too powerful for my cabinet, so I got a VFD to slow down the extraction rate so that only the dust gets sucked in, but I'm still having a hard time finding the correct solution to cover up the 135 mm inlet so that abrasives that ricochet off the cabinet walls and doors don't get sucked in.
I can't place a filter as those will get clogged pretty much instantly and the idea is to extract the dust to outside my shop.
I asked ChatGPT and it told me to place a perforated steel plate in front of the exhaust port to prevent abrasives from getting sucked in, but as can be seen in the second picture, there is still a gap where the abrasives can fly right into the port without first hitting the plate and falling down.
Should I seal around the perimeter of disc?
Not sure what industrial cabinets use to solve this issue so I thought I'd hear your opinions on the matter.
