Bag Filter Filtration System

This is my most recent filtration system. It should cost around $75 with shipping. For my first system I used a water filter. It worked okay but clogged a lot. That system can be seen here.

The parts were ordered from the following companies

Home Depot
The 5/8" ID tubing
Standard 5 gallon pail. No lid needed. (Two, one with a lid, if you don't want to buy the screw top bucket listed above.)
5-6 inch stainless steal clamp.
You will also need a hole saw (picture below) for putting in the tank fittings.
Hose clamsp for the barb fittings
TFE (Teflon paste) for high temp applications. A pluming supply store also may have some. I also read some where to use Permatex #80631. I used something from home depot that had PTFE in it. I used this in some fitting in my car conversion so I used it on the fitting in this filtration system and it seemed to work.

First drill the holes for the tank fittings. Mount the tank fittings in the top and the bottom so the o-ring is on the inside of the bucket. I cut the top off the one on the bottom of the bucket so less oil would remain in the bucket. Assemble the fittings and the filter bag adapter. Use some thread sealer. Install hose barbs in each tank fitting. The straight one goes on top and the elbow goes on the bottom. Cut hole in the standard 5 gallon pail. Connect hoses and clamps and you are ready to go.

I run it at about 5 PSI. Do not screw the lid on while running these buckets are not meant to hold pressure. Just leave the lid loose.

I'm going to try some new filter bags so. I'm trying ones that are heat welded at the bottom instead of sewn since I run with pressure and the holes from sewing may create leak paths. I'll update the site once I get some experience with them.
