What is the difference between OF, and BIO filters for boilers?

Does OF mean for oil, and BIO mean for boilers that run on red diesel? Thank you.

I don't dabble with bio mass or oil but your question doesn't make a lot of sence.. Care to elaborate?

I'm not too sure what you mean here, but in an attempt to clean up emissions from oil boilers, a percentage of bio fuel is added to the blend. Typically this was in the region of 5% but can be as high as 10%.
Unfortunately this had the effect of destroying the seals in pressure pumps, and a new sealing compound had to be made before the pumps could be reliable again.
An excess of bio fuel has also the effect of making the kerosene harder to ignite......Danfoss apparently redesigned their igniter units to help with this.

Sorry I should of been more clear. I am looking at oil filters for oil boiler. What I see is there is two types of oil boiler filter the same size. For example you have a OF493 filter and a BIO-493 filter they fit in to the same filter bowl. So does OF mean for boilers that run on kerosine and BIO mean to run on red diesel?

@Ben ten ten No the BIO means that it can be used on Biofuel as well as kerosene and fuel oil whereas the OF will not cope with Biofuel just kerosene and fuel oil.
