Description

• To avoid or minimize bypass during cold start the actual assembly clean ΔP calculation
should be repeated for start-up conditions if cold starts are frequent.
• Actual assembly clean ΔP should not exceed 10% of bypass ∆P
gauge/indicator set point at normal operating viscosity.
• If suitable assembly size is approaching the upper limit of the recommended flow rate at the desired degree of filtration consider increasing the assembly to the next larger size if a finer degree of filtration might be preferred in the future. This practice allows the future flexibility to enhance fluid cleanliness without compromising clean ΔP or filter element life.
• Once a suitable filter assembly size is determined consider increasing the assembly to the next larger size to optimize filter element life and avoid bypass during cold start.
• When using water glycol or other specified synthetics we recommend
increasing the filter assembly by 1~2 sizes.
