Dust Separator Comparison

For those with larger collectors (e.g., four inch and larger hoses/pipes), look into fertilizer supply houses for your collection cans.

I have two 30 gallon and one fifty-five gallon, blue, plastic drums. They cost me nothing.

One of the 30's has been running under the Super Dust Deputy in front of my 3 horse, 4 bag system for a few years. It shows zero sign of collapse. It has a long, vertical plexi view port, which I riveted and siliconed in place, and which allows me to monitor fill level. Handles and wheels make it easy to transport (I use it in the yard, to vacuum pine cones and leaves).

I check the seal between the lid and the can with incense. If it leaks, the vacuum will try to collapse the can, and will cause the wire cage to squish in a little, as the vacuum tries to grab the bag. In short, if you are collapsing cans, you, likely, have a leak between the can and the lid.

SIDE NOTE:

I use clear plastic bags from a big box store. I made a wire cage to hold the bags in place. Even with those in place, I can still see through the view port and bag to determine fill level.

When full, you CANNOT lift the bags out. The harder you lift, the more the bag presses (expands) against the sides of the can. However, by merely tipping the can over, the bag, along with its contents, spill out for easy removal.
