Filter is not inside-out!

Hydraulic systems & components
DirtCatcher elements from Schroeder Industries, a leader in filtration and fluid conditioning products, are outside-in flow elements featuring a patent-pending outer shell that prevents contaminants from falling back into a system during element changes. The outside-in flow design provides better pleat and seam stability than inside-out design because it causes dirt loading to occur in compression rather than in tension. Fluid flowing from outside-in has the effect of opening the pleats, thus avoiding undesirable pleat bunching and impeded flow that often occurs in inside-out flow elements.
Figure 1. Outside-in construction: flow opens the pleats
Available in Excellement synthetic media, the DirtCatcher delivers all of the advantages of Schroeder’s original outside-in flow elements (low pressure drop, excellent dirt retention, and high efficiency) while completely containing the contaminants within the element’s outer shell. This being the case, the run-off fluid from a discarded element is actually clean and can be captured and recycled if desired.

DirtCatcher elements possess a unique physical size, allowing OEMs to retain 100% of their after-market business. The outer wrap can also be privately labelled.
The new elements are available in single or double length K-size elements and are totally interchangeable with Schroeder KZ and KKZ elements. The elements can be purchased separately or incorporated into Schroeder’s RT, KFT, KF3, KF8, and KT filter assemblies.

Hydraulic systems & components
Those working with hydraulic or pneumatic systems know that keeping your machinery running at peak performance balances productivity and cost. As systems age, they often become less efficient, requiring more energy and more frequent repairs. The good news is that you don’t always need to invest in an entirely new machine to solve these problems.
