Where and Why Use
®
Donaldson’s famous Duramax filters are the highest rated medium
pressure filters available in a spin-on configuration. Duramax are
reliable, sturdy, long-lived and easy to install. Most often used as return-
line filters, they are designed for working pressures up to 1000 psi and
static pressures up to 2000 psi.
