TF4 FILTER ASSEMBLY SELECTION AND SIZING GUIDELINES
Effective filter sizing requires consideration of flow rate, viscosity (operating and cold start), fluid type and degree of
filtration. When properly sized, bypass during cold start can be avoided/minimized and optimum element efficiency and
life achieved. The filter assembly differential pressure values provided for sizing differ for each media code, and assume
150 SSU (32cSt) viscosity and 0.86 fluid specific gravity. Use the following steps to identify the correct high pressure filter
assembly.
1. Calculate Dp coefficient at both operating and cold start viscosity:
Actual Operating Viscosity (SSU)
Dp Coefficient =
Actual S.G.
X
150
0.86
2. Calculate actual clean filter assembly Dp at both operating and cold start viscosity:
Actual assembly clean Dp = Flow rate x Dp Coefficient x Assembly Dp factor (from sizing table)
3. Sizing Recommendations to optimize performance and permit future flexibility:
•
•
•
•
•
To avoid or minimize bypass during cold start the actual assembly clean Dp calculation should be repeated for
start-up conditions if cold starts are frequent.
Actual assembly clean Dp should not exceed 5 psid 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 Dp 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.
High viscosity fluid (ie gear lube ISO 220) will typically display very high viscosity as the temperature drops
below 100°F. For such applications avoiding bypass during start-up might not be possible.
