Hydraulic and Lubrication Filters

Introduction

Eaton currently offers a selection of more than 4,000 different Internormen filter elements, including corresponding filter housings. Eaton’s Internormen product line includes a wide range of filters that have been the industry standard for many years. They provide customers with a different kind of filtration—from tank-mounted return line filters, to in-line or flange mounted high pressure filters, to manifold side mounted or manifold bottom mounted pressure filters, to air breathers and suction strainers.



Low Pressure Filters

Eaton’s low pressure filters are suitable for a working pressure up to 1450 PSI (100 bar). Pressure filters are used to protect downstream components from contamination levels beyond the recommended cleanliness target. In systems using accumulators, pressure filters must be sized according to the large effective flow rates present during parts of the duty cycle.

High Pressure Filters

Eaton’s high pressure filters are suitable for a working pressure higher than 1450 PSI (100 bar). Pressure filters are used to protect downstream components from contamination levels beyond the recommended cleanliness target. In systems using accumulators, pressure filters must be sized according to the large effective flow rates present during parts of the duty cycle.

Return Line Filters

Eaton offers return line filters in various designs and for different application possibilities. The housings can be mounted in-line or directly within the reservoir itself (sometimes referred to as an in-tank filter). Ideal for use in mobile applications.

Return line filters may also be equipped with additional breather filters. Secondary ports may also be incorporated to add make-up fluid and ensure that the fluid is transferred through a filter before entering the system.

Suction Filters

Eaton suction filters protect hydraulic pumps and control systems from solid contaminants. They should be used as immersion suction filters on pump inlet lines. These units have various application possibilities: as in-tank filters mounted directly to the reservoir, in the intake lines of hydraulic pumps to afford a degree of protection from contaminants to the pump and other components in the hydraulic system.


Features:

The practical design of the Eaton suction filters makes service easy. When releasing the filter lid a plate valve closes the suction-inlet of the filter and prevents the return flow of dirt oil to the reservoir, respectively when mounted horizontally the flow out of the reservoir is prevented.

After servicing change the element the filter is ready for operation.

According to operating conditions, different accessories (clogging indicators, counter flange, etc.) are available for the filter.

Stainless Steel Pressure Filters

Eaton Internormen high-quality stainless steel filters are ideally suited for filtration of highly contaminated liquids, fuels, lubrication oils, solvents, machine tool cooling lubricants, chemical process cleaning fluids, and for filtration of cooling water and seawater.


Features:

The strength and durability of Internormen stainless steel filters is unsurpassed. Their resistance to corrosion makes them suitable for water and emulsions in off-shore technology, the chemical and food industries, water treatment plants in the power industry, and in cases of extreme outdoor and environmental conditions.

Duplex Pressure Filters

Eaton Internormen duplex pressure filters are known for their high intrinsic stability and excellent filtration capability. These filters operate continuously, when the first filter needs replacement or maintenance, an integrated rotary slide valve switches flow to the opposite side without interruption to flow. This enables a system to work continuously without interruption or shutdown.


Features:

Eaton's duplex filters can be mounted into suction, pressure or return lines and are designed for continuous filtration without system shutdown. Replacing the filter element is easy. Simply open the shut-off valve for pressure equalization then switch the filter to the opposite side. The DA and DNA series are certified and build according to ASME standards.

Spin-On Filters

Spin-on filters typically consist of a head mounted directly in-line with the return piping and a canister containing an element which screws onto a threaded post.


Features:

The In-line filter series WPL spin-on-filters are suitable for an operating pressure up to 145 psi (10 bar) and are chosen for mounting into pressure lines and return lines. The spin-on-filters directly screw to hydrostatic drives. These series allow an easy maintenance with short operating interruption. After use, replace the complete spin-on-filter. A pressure switch and pressure gauge are available for the WPL-filter.

Off-Line Filters

Eaton's Internormen Off-Line Filters are partial flow filters for fine filtration of hydraulic and lubrication circuits meant as a supplement to the main filter. Off-line filtration improves the cleanliness and quality of operating fluids and prolongs its durability, thereby preventing early wear and tear of system components.


Features:


Eaton's Internormen NF-series off-line filters offer a large filtration area in a compact size allowing for high dirt-retaining capacity even with a small filter fineness. The easily accessible filter element can be changed quickly and without tools.

Breather Filters

The Eaton Internormen tank breather filters "breathe" air in and out as the oil level rises and falls. The filters prevent the penetration of contamination form the ambient air in the hydraulic fluid. This circulating air contains articles and moisture that can cause corrosion, increase equipment wear, and reduce fluid performance. In typical systems, the internal hydraulic fluid is warmer than the external environment. This difference in temperatures causes water vapor to form. Breathers protect your hydraulic system by filtering out damaging moisture and particles.


Features:


Desiccant air breathers prevent water and other contaminants from entering fluid reservoirs where differential pressures can occur through thermal expansion and contraction of the fluid, or during filling or emptying procedures. Breathers utilize the entire filter area and have the ability to extract water vapor out of the air as soon as it enters the unit. Accompanying solid particles are removed by a 3 um absolute glass filter, allowing only clean, dry air to enter the system.
