For Sale: Puradyn bypass filter

[Delfin]

I ordered a filter for my Puradyn bypass filter and received the filter, plus a complete filter body with mounting brackets which I don't need. So, best offer over $100.00 plus shipping buys it. Retail is over $900. This is a PFT 40 that is good for engines with up to 25 gallons capacity. Oil is filtered at a rate of 6 gallons/hr to 1 micron, effectively eliminating all friction wear. You can triple your oil change interval with a filter change at the recommended interval if you wish.

Puradyn has changed their model numbers, but the system has remained functionally the same.

Does this accept the newer filter elements? The PFT looks like a legacy unit, but if it uses current elements I might be interested.
What else would be needed to complete the installation?

Based on the measurements for the 'new' filters, they are exactly the same as the old. I believe they discontinued this model as the functionality was exactly the same as their now remaining model. Plus, this one has a large lid that screws on, requiring a long ratchet to open, where their remaining model has four wing nuts holding the lid on. I use a torque wrench to open mine. In any case, the concept is simple. They push oil at a slow rate from the pressure side of the oil channels through a one micron media and return it to the sump via gravity. There was no reason to change filter design, so it looks like they just changed stock numbers.

The extras you need are a ball valve to shut off the return oil to the filter for isolation and a robust flexible oil line to tap into the pressure side of the oil channels. A valve at the tap point is included. On my CAT 3306 there were a couple of such tap points, so installation required having a bracket made so I could mount the unit on the CAT, and having the 1/4" pressure line made at a local hydraulics shop. This is a new unit, so all the brackets, nuts and bolts, etc. are included.

I had the exact same Puradyn Filtration system on my 3306 Cats and both of my generators. Can say enough good things about this system!
