Its a filter head and pleated cartridge filter that removes down to 6 micron...
It will pass up to 114 liters a minute- so has a far faster flow rate than the cotton wound bypass filters!.
As a result Donaldson don't recommend running it off say a T joint from your oil pressure sender switch and passing the oil back thru a Banjoe bolt in the top of the oil filler cap for e.g. - because it will possibly drop oil flow & pressure to your engine components from the oil pump, too low!
You can however buy electronic continuous flow 'supplemental' oil pumps, where you pump the oil from the sump thru the bypass filter separate to the engines main oil pump reticulated system in order to scrub it clean.
The Donaldson recommendations are:-
It is another option when you think about it.a P561134 head assembly with a P564967 6um@b1000 hydraulic filter. This will handle a flow rate of up to 114lpm, however I suggest a low volume pump of under 2 – 5 lpm would be sufficient for your application.
We do not recommend drawing oil from the main supply line as this can reduce the oil flow to the engine.
But it's also more cost for a 12 Volt continuous rated oil transfer pump plumbed into the system.
At least it does avoid the need to hive off say 10% of the OEM oil pressure and volume... to work the bypass filter to scrub the oil clean...
A separate and electric operated supplemental oil pump, would also be capable of operating a mechanical centrifugal oil "spinner" filter system as well!.
Maybe there's a market to leave the OEM oil system alone (i.er.no adapter plate over the OEM oil filter mount) and instead pump the oil out direct from the sump and thru a bypass sub micron filter and thru a spinner centrifugal filter and back to the sump then under gravity!.
In an ideal world - an electronic oil pump could be wired to your key on circuit and pre pressurize all journals bearings and cylinders etc BEFORE you engage the starter motor - (a pre - oiler) as well coz most wear occurs at start up while the high viscosity cold oil is still sitting in the sump and hasn't yet got to the working parts until after the engines started.
You'd think in today's modern technology age that manufacturers would pay more attention to the lubrication side of their engine products. There are so many different after market add ons, why aren't they standard fitment items?.
Dunno how to link in a emailed PDF file into this forum post.... with the Donaldson Filter head and filters.. parts details...
The filter head retails around $39.00 & the pleated cartridge filter cannister around $28.00
Part numbers T561134 & T564967 respectively.
You'd need braided oil pressure hoses and some kind of 12V continuous rated oil transfer pump as well I guess.
