So far the only upgrade I have completed is adding an inline exhaust fan. I have been very pleased with my Cloudline AC Infinity inline fan. I have a 60w OmTech and this 6 inch fan was the perfect fit for my machine.
Why do you want this upgrade?
It removes the smoke from your machine at a much faster rate than the stock fan in your machine. I don’t even notice a smoke smell in my garage because this fan sucks it out of the garage and out the dryer vent on the side of our garage super fast! Reduced smoke residue on my wood projects means less sanding and finishing afterwards!
If you install this fan, make sure you remove the stock fan at the same time. You will want to take it out so you don’t have a reduced air flow from it having to pass through that first.
