Oil Filter Mesh and Flow

[Baracoa]

Is it possible that a wire or plastic mesh in an oil filter affects either the flow rate or the total media available for filtration? I am thinking in particular about the PurolatorBoss that has an integrated polymer mesh. Does that not take away media space?

Thinking how the media is situated in relation to the core , I can’t see anything like this happening.

No. The concern you raise is a fallacy and a non-issue.

The polymer mesh is used to support the filter media and assist in the media maintaining its shape. Synthetic filter media does not have enough internal stiffness to maintain its shape on its own while in service. So manufacturers use a stiff backing matrix to hold the filter media in place. It prevents wavy pleats over the life of the filter.

Other manufacturers accomplish the same thing with a wire backing. Neither approach (polymer or wire) is superior to the other, rather just different approaches to solving the same problem.

You're welcome.

No effect ... see flow vs delta-p date here. Fram Ultra and Purolator Boss were included in the tested filters.

Would you all like to see ISO 4548-12 Oil Filter Lab Testing Comparison, Efficiency & Capacity, Pressure vs Flow, Bubble Point, and Burst?

You switched your temps here, but yes exactly. It's easier to heat a fluid up then to cool it down to reach a target viscosity. I also don't like to get fluids to hot. Around 40C is where I don't like to go beyond if I can help it. Nice graphs and homework on this equivalency!
