GMF iprotect® Medium Pressure Filters Max. 600 I/min - 70 bar A compact, cost effective medium pressure filter Designed with the iprotect® patented filtration technology The Parker GMF iprotect® is designed to provide high quality filtration of hydraulic systems, providing new possibilities to reduce the cost of ownership by improving the productivity and profitability. A new patented design of the filter element ensures the quality of filtration is secured. With less space available for filters, Parker has taken on board the requirements to provide more compact solutions. A unique feature is the filter element remains inside the filter bowl when changing the filter element. This can save over 500 mm of space envelope in comparison with traditional medium pressure filters.

Pressure Drop Curves With 1.7 bar bypass the recommended initial pressure drop is max 0.5 bar. With 3.5 bar bypass the recommended initial pressure drop is max 1.0 bar. With 6.0 bar bypass the recommended initial pressure drop is max 2.0 bar If the medium used has a viscosity different from 30 cSt, pressure drop over the filter can be estimated as follows: The total Ap = housing Aph + (element Ape x working viscosity/30).
