HIGH PRESSURE FILTERS

APPLICATION HIGH PRESSURE FILTERS For Manifold Block Side Mounting Series DF...QE Pressures to 4 psi Flows to 18 gpm HYDAC DF...QE High Pressure Filters are designed to be side mounted directly onto the manifold block remaining vertically positioned to save space and reduce leak points and mounting hardware. These filters can be installed on the high-pressure side of the pump to protect control valves and actuators from contamination. PRODUCT FEATURES The DF...QE Filters have a filter head of ductile iron and a screw-in bowl of cold-formed steel. The filter housings are designed to withstand pressure surges as well as high static pressure loads. The screw-in bowl allows the filter element to be easily removed for replacement or cleaning. A visual (pop-up), electrical, electrical/visual (lamp), or electronic differential type clogging indicator can be installed. DF...QE filters are available with or without a bypass valve so either high or low collapse pressure elements may be used. FILTER ELEMENTS DF...QE Filters are available with disposable Betamicron Low Collapse (BN3HC) elements having psid collapse pressure and Betamicron High Collapse (BH3HC) elements having 3 psid collapse pressure with absolute ratings of 3,, 1, and 2 micron. DF...QE Filters are also available with cleanable elements. Metal Fiber (V) stainless steel fiber elements have a 3 psid collapse pressure and nominal ratings of 3,, 1, and 2 micron. Wire screen (W/HC) elements have a psid collapse pressure and nominal ratings of, 74, and 149 micron. For non-bypass applications, Betamicron (BH3HC) or metal fiber (V) elements must be installed. If a bypass valve is used, Betamicron (BH3HC) or wire screen (W/HC) elements can be installed. All filter media is supported to achieve flow fatigue resistance. Proper support of the filter media also provides high Beta Ratio values (particle removal efficiency) even at high differential pressures. The efficiency of many competitive elements drastically DF...QE FILTERS deteriorates as the element clogs and differential pressure increases. High quality epoxy adhesive is used to bond the end caps to the media and to bond the seam of the media.

Other Products from HYDAC s Filtration Line Filtration Solutions For Mobile Equipment Although there is great diversity in mobile equipment designs, the common demand in the industry for improved performance has resulted in systems growing in complexity and cost. Precision hydraulic components variable displacement pumps and motors, load control valves, and proportional controls are increasingly applied to enhance machine power, speed and versatility. Higher operating pressures in excess of, psi are increasing in usage in order to generate higher force and torque from a smaller and lighter package. As fluid power systems are built to function more precisely at higher pressures, protection against wear and malfunction becomes vital. HYDAC s range of filtration products are designed to provide the necessary level of protection to maintain the efficiency, useful life and safety of high performance fluid power systems. Request catalog # 29743 BETAFIT Filter Elements HYDAC manufactures high quality filter elements that are dimensionally similar to other manufacturer's elements and will fit interchangeably into their filter housings. This catalog lists the interchange elements and the models which they replace and is organized by manufacturer. Even When your hydraulic or lube oil system doesn t have a HYDAC filter assembly, it doesn t mean that you cannot benefit from our Betamicron Element technology. The high beta ratios and leading dirt holding capacities of these elements extend service life and provide a greater price to maintenance cost ratio than elements from other manufacturers. Request catalog # 273 Condensed Filter Catalog This condensed catalog serves as a quick reference guide for selecting HYDAC filters. The models are divided into high, medium, and low pressure groups. Charts then describe each filter in the group. Each model description includes mounting method, maximum operating pressure, maximum flow rates, number of sizes and connection size range, flow path, clogging indicator type, and a brief description of features and benefits. General information about clogging indicators, element types, breathers, and filler breathers is also included. Request catalog # 28118 Filtration Technology HYDAC Filter Technology is the result of many years of research, development and performance evaluation both in test stands and actual applications. HYDAC s Filter Division produces a complete range of filters. This range includes in-line, in-tank, inside-tank, direct mount, and manifold mount, modular stacking filters. Also available are duplex models for systems requiring continuous operation. This catalog provides a general overview and photos of HYDAC filter families with information on pressure and flow ratings, and mounting types. It serves as a handy reference to select the appropriate series of filter(s) for the application in need of filtration. More detailed literature that includes specific technical data and dimensioned drawings is available for all models.
