Frantz oil filters
I found these remote filters which are a bypass type.
they seem to be the old toilet paper roll filters of years ago. http://wefilterit.com/index.htm Has anyone tried them? They hook them to the oil pressure sender line and back to the oil pan, is there enough flow there to make for usefull filtering and where do you get oil pressure for the guage? I have an O290 with an oil cooler and a screen, could it be hooked inline with the oil cooler or would it be too restrictive? In a past life I worked on transport trucks and serviced an oil filter which used a canister with flinger inside which spun around by pointing it's nozzle. The dirt would stick to the outside of the canister which was cleaned by removing a paper liner. Other than being iron, a bit heavy and having a moving part to wear or break they seemed to work well. I was impressed with the layer of dirt I pulled out with the paper liner. Ray Toews 1965 Jodel F11 CF-OVJ |

My Step-dad used to use one in his 70 Maveric. Oil filters have improved in recent years- why use an old filter like that? Is you life worth more than a roll of TP? I know mine is! -- (¯`·._.· £ãrrÿ ·._.·´¯) ztoewsatincentredottnet (Ray Toews) wrote in message ...

I used to install them on engines. I would love to know where you found
them and if you can get me any??? The Frantz is a great bypass oil cleaner. Most people don't understand how a bypass oil cleaner works. Please let me know about getting more Frantz cleaners -- Have a good day and stay out of the trees!

Still have it in my junk somewhere. The oil in that truck was always clean; would darken a bit from heat, but no carbon in it. The filter has a tiny orifice feeding it so that minimal oil pressure is lost in bypassing the engine's oil system. It would NOT work as an inline full-flow oil filter because of that restriction, and because the toilet paper presents so much restriction by itself, especially as it accumulates junk. It's hard to find toilet paper that will fit it anymore. The retail types of crapwrap are loosely wound and are on larger ID rolls than formerly. They won't fit the canister and centre post properly. Service-grade rolls are necessary, and they are available only in cases of 48. Lots of filters, but at the same time you can save cash on the stuff since a roll will last many times longer in the biffy and costs only marginally more than the retail stuff. You want 500-sheet singly-ply, and it has to be good quality paper. I'd put the filter in my Jodel but I fly it so infrequently that the oil doesn't have a chance to dirty up much between changes, and the weight of the filter cuts into an already-small useful load. The filters are still manufactured, I think. Maybe a Google search might turn something up. Dan |

The submarines I was on all used synthetic oil, and had centrifugal
bypass oil purifiers. They never changed the oil. In fact, the reason you use a bypass filter is so you don't have to change the oil, and because the bypass filter also removes water. Also on the submarine, the sailors discovered that toilet paper rolls make very effective filters. If you exhale your reefer hit through the edge of the roll, it filters out all the smoke, making it undetectable. Street price for new Frantz filters looks like around $135 (on Ebay). You can buy them new from the manufacturer: http://www.wefilterit.com/ Dan Thomas wrote: "Gilan" wrote in message link.net... I used to install them on engines.

I gave up the system of allowing the oil to get dirty wear and foul
the engine then draining it in 1963. I started with the Frantz. When Motor Guard came out in 1966 I started using them. I liked the design better. I believe the Aero Frantz got FAA and PMA approval in about 1971. I have letters from a couple of users of the Aero Frantz. There are a few still in use on small military aircraft. I ran onto a crop duster outfit in Kansas that used them. They were designed to use 1 1/2 core toilet paper. When the paper companies changed to 1 5/8" Frantz came out with their own elements. Motor Guard went into the more lucrative industrial market. Motor Guard beefed up their die cast aluminum housing and put an epoxy coating on them. They are mostly used in electronics. They are used in plasma cutting, plasma etching, air filters where clean dry air is a must such as painting aircraft. Some are used for synthetic oil in vacuum pumps. The Motor Guard has the advantage of being a compressing type filter. I like them because they are very easy to service. I have been lathe turning internal parts to fit the more common 1 5/8 core tp. I take enough paper off to make the roll 4 1/4 diameter. The company I work for furnishes me with tp called Mainstreet which is just the right size. Scott 1000 sheet is very high quality but about 50 rounds too large. After 40 years you get to be an expert tp squeezer. The FAA and PMA models are gone unless you can find a used one that someone doesn't know what it is worth. The FAA and PMA model had a clamp that bolted on instead of the automotive over center clamp. Motor Guard never got into aircraft filters. It's a hassle with all the red tape. Filters that clean oil down to well below one micron have always been of interest to me. Oil doesn't wear out. It gets dirty and you can burn it up. I keep it clean and don't run it too hot. It is very hard to wear out equipment with clean lubricants. Dirty oil generates good profits. Clean oil only generates long equipment life. I was asked about installing a filter on a Spit Fire. He said the FAA approval wasn't necessary. It's a company that restores old aircraft. I think he mentioned a Rolls Royce engine. My guess is he found an old Aero Frantz. He was looking for one. I think the Frantz was his first choice. I like to use a sandwich adapter with the Motor Guard. If the engine has a spin on filter the sandwich adapter makes a nice installation. You install the adapter between the block and the full flow filter. All of the oil goes thru the full flow filter but some is diverted to the Motor Guard to be cleaned first. I can get either the Flex-A-Lite or the Perm-Cool from Jegs.com high performance parts. I prefer the Flexalite because they put a bypass valve in the GM engine adapters. The Frantz, Motor Guard and most other bypass filters have a 1/16" orifice so that the filter won't rob too much oil from the system when teeing off at the sending unit or gauge fitting and returning the clean oil to the sump. I don't know anything about aircraft engines but a VW Beetle oil pump has plenty of oil pump capacity to supply the engine the filter and still bypass oil from the oil pump to the sump. I have two v twins that work very well with the sandwich adapters. The adapters don't take oil pressure from the engine. Ralph guynoir wrote in message link.net...
