Prefilter- screens denim, etc?
November 7, 2010 - 1:22pm
I've got a centrifuge system close to setup and I realized theres something I've given almost no thought to: how do I prefilter. I'm thinking like a rinseable window screen material to pour through before it goes to my settling/heating tank. Thoughts?
What do you guys use to get the fishtales, etc out?

Let me jump in on this. I thought I was getting pretty clean oil. Well I am not. I need to prefilter. I used a regular pant leg from a pair of dockers and the flow is terrible. Will jean legs flow better? I am trying to get the big floater items out.
thanks

I have been told that the denim will flow FAR better than the docker type material. I have, however, not moved to denim to try it.

I have a 2" pipe coming out of a storage tote. I use a large clamp to attache two tube socks, one inside the other, to the end of the pipe. After about 40 gallons the flow is almost nothing, so I put another pair of socks on, so I know it is getting alot of junk out of the oil. After doing that, all of the oil will go through my DieselCraft OC20 centrifuge.

seems like the frybrid method of clamping a bed sheet on a drum is the best way to go im new to this so im just speculating based on my own logic. maybe some of the experts can weigh in on this method...

Since I am swimming in oil, I simply pour the cubies through several sections of nylon screen material into a large holding tank (leaving the bottom "gunk" in the cubies for the fire pit.)
I heat and gravity feed the unflitered oil right into my centi and will allow it to re-circulate back into the same holding tank (tote.)
The oil will get very clean.
When I start employing this new filtration method in the spring, I will most likely sell all of my hanging filter bags, GE whole house filter system(s), hundreds of filters I have in inventory, some nice agriculture and other poly tanks, 55-gallon drums, various lids and stuff.
I am located in lower New York (near the city.)

I am pre-filtering through a bed sheet unheated and only about 6 to 7 gallons make it through before it is clogged up and stops passing any more. The surface area of the fabric doing the filtering is probably around 2ft square. Currently I am only collecting about 8 gallons a week so it doesn't affect me much, but when I ramp up the collection it will probably slow me down a little.

Just an update - I found some washable screens. EZ-Strainer. Check on amazon.com and type in "EZ-Strainer 55 gallon"
I use a 600, then a 400 in line on top of a barrel and pour 8-9 cubies into the barrel (basically, full)
I did get a 300 and a 200 as well, but they clog way too quickly for my prefiltering needs, so I suggest the 600 & 400 only.
