Filter Cloth Micron Rating:

This data was determined using the "bubble point" test method. One micron equals 0.00003937" or 0.001mm.

Filter Cloth Flow Rate Data:

This data was based on a test sample one square inch in area.

Oil - MIL-H-5606-B @ 80�F (viscosity 90 SSU) at 1 psid.

Fuel - MIL-F-7024-A, Type II @ 78�F (viscosity 35 SSU) at 1 psid.

Air - Tested @ 75�F at 1 psid.
