Medium Pressure Filters

Donaldson DURAMAX®, well-known as the highest rated spin-on style filters available, are most often used in return-line positions. As spin-ons, they are particularly well-suited for duplex circuits. Donaldson Synteq® and cellulose media available. DURAMAX working pressures range from 350 psi up to 1000 psi; static pressures from 800 psi up to 2000 psi.

HMK03 Duramax®

HMK03 Duramax®Working Pressure: 1000 psi / 6895 kPa / 69 bar
Static Pressure: 2000 psi / 13790 kPa / 138 bar
Flow Range: 0-25 gpm / 0-95 l/min
HMK03 offers TWICE the pressure capability of competitive filters, yet is physically smaller than traditional housing/cartridge filter assemblies.
