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.

 

Characteristics:

– The filters can be installed as suction filters, pressure filters or return-line filters.

– Coarse filters of the GFK series are suitable for a working pressure up to 16 bar.

– The GFK filter elements are filter baskets with steel wire mesh as filter material. The perforated center tube is layed out with steel wire mesh. The flow direction is from inside to the outside.

– In-line filters of the LF series are suitable for a working pressure up to 32 bar.

– The LF Series filter element consists of star-shaped, pleated filter material which is supported on the inside by a perforated core tube and is bonded to the end caps with a high-quality adhesive.

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.

 

Characteristics:

– ML, MNL series are designed for mounting in pressure lines. Economical, lightweight filters for low to medium pressure applications. Require minimal clearance during element change.

 

– HP filters can be in-line or flange mounted in pressure lines and are able to accommodate very high flow rates with a single housing. Various designs, port and indicator options available.

 

– HPW series are filters for flange or threaded mounting, for reversible filtration, to be used where filtration can occur in both directions.

 

– HPV, MDV are in-line pressure filters guaranteeing a permanent supply of clean oil: if the element clogs, change is forced, which means no damage is possible to downstream components.

 

– Series MNU, HNU, HPU and HPP are designed for flange or manifold mounting in pressure lines, thereby saving space and providing filtration directly at the point needed.

 

– HPF, HPX and HPY filters are meant for manifold mounting in pressure lines, providing filtration exactly where needed, thereby preventing contaminants from passing downstream during filter element changes.

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.

 

Characteristics:

– Return In-Line Filters RF series are lightweight aluminium design filters, designed for connection in return lines

– TEF series, In-tank Return Line filters are easy to change with multiple inlet ports and a removable bowl which prevents contamination from entering the reservoir

– TEFB series are In-tank Return Line filters with additional air breather

– TRS, TNRS series are tank-mounted return line filters with suction connection suitable for mobile hydraulic applications with a minimum of two independent hydraulic circuits

– TRW series are horizontal return line filters for mounting below the tank fluid level.

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.

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.

– DU Series

– DSF Series

– DNR Series

– DUV Series

– HDD Series

– DNA Series (according to ASME)

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.

 

Characteristics:

  • – Available in 4 sizes
  • – Refillable with drying agent
  • – Available with adapter and clogging indicator
  • – Replacement spin-on air filter available separately
  • – Seal and plastic plug prevent moisture entering before installation

 

Applications:

– Diesel fuel storage tanks

– Transformers with oil cooling systems

– Vacuum and welding chambers

– Agricultural equipment
