Reply to "Joules5: non bypassing oil filter"

Hi George!

The answer on the Pure Power filter question is yes/no. The filter is of modular construction allowing the user to run the bypass valve, or remove the valve and insert a block off plate, I could take photos of how this works if desired.

I agree that dirty oil is better than no oil. But the pure power filter is made of surgical grade stainless steel screen that has a filtration capability equal to or better than paper/composite filters. However, the "filtered oil" flow rate with the screen far exceeds that of coventional filters (try blowing oil through paper sometime) a bypass valve is not required.

Then why do they offer a bypass valve? I asked this question to the pure power filter engineer last month at SEMA. His reply was that the valve was instituted as a "feel good" implimentation since most people relate no bypass valves with either pressure loss or filters bursting. He further went on to explain that the flow rate is so high with the screen element that the bypass valve is not needed since filtration resistance is lower than that of the standard bypass valve PSI rating.

Yes it's true, you can have your cake (100% filtered oil) and eat it too (and improved flow rate). New technology, although pricey, is a wonderful thing.
