Most fluid-power users understand that particulate contamination in hydraulic oil can markedly degrade the performance and life of mobile and industrial machinery. Perhaps less recognized is that water contamination in the oil can similarly lead to component failure. Water, whether dissolved in the oil, present in an emulsion or as free water, … [Read more...] about Portable dryer keeps water out of hydraulic oil

DES-CASE reimagines the oil sight glass
Des-Case Corporation, a global manufacturer of specialty filtration products has launched an entirely redesigned oil sight glass (OSG) that pushes the boundaries of what oil sight glasses can do. A clear cylinder that installs in the drain port of the oil reservoir of pumps, gearboxes, bearing housings and other pieces of equipment, the sight … [Read more...] about DES-CASE reimagines the oil sight glass
When should you use a filter cart?
Filter carts are mobile kidney loop systems that contain a motor, a pump and a filter to form an independent unit. Filter carts can generally be used in two different ways: as enhancement to existing hydraulic system filters, and as fluid preparation for use in hydraulic systems after an event (e.g. replacing fluid, repairs, maintenance, etc.). Dan … [Read more...] about When should you use a filter cart?
Better performance density for filters from ARGO-HYTOS
The primary objective for developing ARGO-HYTOS’ EXAPOR MAX 2 filter element was greater machine availability, longer service intervals, lower-cost spare parts, and lower operating costs for machine operators in the area of mobile and industrial hydraulics. To improve the performance density of the filters, ARGO-HYTOS engineers took a closer … [Read more...] about Better performance density for filters from ARGO-HYTOS
How are hydraulic filters constructed?
Hydraulic filters are an example of a product that began as a very simple solution but progressed over the years to be quite complex. Jeremy Crookshanks Product Manager, Hydraulic & Lube Filtration for Schroeder Industries said that while they still perform the same basic task of protecting sensitive hydraulic components from contaminates, due … [Read more...] about How are hydraulic filters constructed?
How does a coalescing filter work?
Large contaminants in a pneumatic system are readily captured by general-purpose filters or tend to settle out of a compressed-air stream. Air dryers can effectively remove water from compressed air. But aerosols—extremely small (≥ 0.1 micron) solid particles and liquid droplets of oil and water suspended in the air—remain in the flow stream and … [Read more...] about How does a coalescing filter work?
What are kidney loop systems?
Hydraulic systems are generally equipped with system filters. The system filters are either placed on the pressure side (e.g. downstream of pumps, before system components) or on the return side (e.g. before fluid is reaching the reservoir). Dan Zoller, Group Product Manager Filter Systems, Schroeder Industries, said that in a case where only … [Read more...] about What are kidney loop systems?
New line of desiccant dryers
Walker Filtration, based in Washington, Tyne & Wear, U.K. and with U.S. headquarters in Erie, Pa., has expanded its line of Pro Dry compressed-air desiccant dryers. Based on customer feedback and the latest controls technology, the new desiccant dryers cut service time in half, significantly increase energy efficiency, reduce noise and are … [Read more...] about New line of desiccant dryers
When should you flush a new or rebuilt hydraulic system?
What causes contamination? Particulate contaminants circulating in fluid power systems cause surface degradation through general mechanical wear (abrasion, erosion, and surface fatigue). Dan Zoller, Group Product Manager Filter Systems, Schroeder Industries, explained that this wear causes increasing numbers of particles to be formed, the result … [Read more...] about When should you flush a new or rebuilt hydraulic system?
