Performance Curve Notes • All flow measurements were made with 32cSt [150 SSU] hydraulic oil at 100°F (37.7°C), fluid specific gravity of 0.9. • The performance curves displayed are for the filter, head or housing assembly. • Filter performance curves will either list media numbers or beta ratings (see circled areas on chart above). These labels correspond with the filter choice tables. Pressure Drop (AP) Correction Formulae To properly calculate pressure loss for viscosity and/or specific gravity, use the filter and housing formulae below to determine the clean filter assembly pressure drop....

Hydraulic Filter Housing Selection Guide Locate the Donaldson model closest to the intersection of the maximum operating pressure and maximum flow rate. If there is not a model at the exact intersection, select the nearest series to the right or above the intersection to ensure a filter that is adequate to handle the maximum operating pressure and flow rate has been selected. Pressure families are color coded in the selection chart for low, medium and high model series. Filter housing styles are identified by their shape. Filter Housing Style Code Medium Pressure High Pressure In-tank Housing...

Selecting the Proper Hydraulic Filter Sensitive hydraulic circuits are vulnerable to a variety of contaminants that result in inefficiency, downtime and excessive repair costs.
