I have made what I think is the simplest cleanest and cheapest vacuum filter system. I have run 75 gallons of syrup through it so far this year without a fault. The syrup is clear. Very clear. It will filter 5 gallons in 2 minutes. This is a video of the design, build and operation of it. The biggest improvement over the CDL design is the tear away filters. Just like dirt bike goggles. Enjoy.
