DURAGAF™ Extended Life Filter Bags Can Improve Your Filtration Process and Save You Money

Why DURAGAF Filter Bags Last Longer

DURAGAF filter bags have a unique design that delivers equal filtration performance with lifetimes 2 to 5 times longer than ordinary felt media bags. This means reduced operating costs due to less bag consumption, reduced downtime, and lower storage and disposal costs. The two charts at the right clearly illustrate the longer service life you can expect using DURAGAF filter bags in your application.

DURAGAF filter bags are available in two extended life materials, polypropylene or polyester. These two materials utilize a fiber blend with a finer fiber diameter and a higher weight than ordinary media. The result is a dramatically higher dirt holding capacity at the same efficiency and differential pressure. Processes run longer and need fewer bag changes with DURAGAF filter bags.

Superior Construction

All welded construction eliminates the bypass that can occur in standard sewn filter bags. Eaton’s proprietary welding technology produces a super-strong seam that will stand up to the most demanding applications without failure. The SENTINEL® ring seal is standard on all DURAGAF filter bags. This pressure actuated sealing ring actually improves its seal as the differential pressure increases. To help prevent unwanted fiber migration DURAGAF filter bags are manufactured with a proprietary downstream surface treatment.

Food and Beverage Applications

DURAGAF filter bags are available in polypropylene and polyester materials that are compliant with FDA and EC requirements for food contact.

Features

• Pinholes, inherent to the sewing process, are potential sources of bypass, thereby reducing bag efficiency. The side and bottom seams, as well as the SENTINEL® rings of POXL and PEXL filter bags are fully welded, thus eliminating this problem.
• The surface of the filter media is subjected to a special heat treatment. This unique treatment reduces the problem of fiber release, while retaining the required surface permeability.
• Increased media thickness enhances the area in which particles are trapped. As a result, a greater amount of particles will be retained.
• The use of micro fibers increases the void volume of the filter media – resulting in longer on-stream life

Cost Effective Filter Bags for Absolute Filtration Applications

LOFCLEAR filter bags now make absolute filtration viable in many applications where only standard bags could be used in the past due to cost constraints. Made from 100% pure polypropylene materials compliant with food requirements, LOFCLEAR filter bags contain no leachables or lubricants such as silicone oils. In addition, their excellent oil absorbency makes LOFCLEAR filter bags ideally suited to the oil removal needs of the paint and coatings industries.

Two Series to Match Filters to Applications

LOFCLEAR filter bags are available in two styles, Series 100 and Series 500. These two styles make it possible to match the requirements of a wide range of applications, depending on the needs for efficiency and long life.

The Series 100 filters use a multi-layer construction for applications where high efficiency is of prime importance. They are an excellent choice for applications such as high-purity fluids with low particulate concentration, first-pass filtration oil adsorption and activated carbon removal. There are also LOFCLEAR Series 100 Filter Bags developed especially for the filtration of electro-coatings and clear coat in the automotive industry.

The Series 500 filters utilize a pleated construction to increase surface area for applications requiring high dirt capacities and long life. Among the many applications for LOFCLEAR Series 500 filter bags are oils, slurries, dilute oil removal, re-circulating batch systems, and systems with heavy contamination.

Perfect for Removal of Gelatinous Materials

LOFCLEAR filter bags have proven to be highly effective in the removal of gelatinous contaminants. The combination of deep micro fiber filtration media breaks up gels and retains them within the media depth. These features prevent surface blockage and breakthrough typical of standard filter bags.

LOFCLEAR Series 100 Filter Bags

LOFCLEAR Series 100 Filter Bags feature a proven three layer construction with a sewn filter welded to the SENTINEL seal. They feature efficiencies greater than 99% over a wide range of particle sizes, with dirt capacities up to 1/2 pound. All models feature a polypropylene prefilter, meltblown polypropylene microfiber final filter and a polypropylene outer migration barrier.

LOFCLEAR Series 100 Filter bags are an excellent choice for applications such as high purity fluids with low particulate concentration, first pass guard filtration, oil adsorption and activated carbon removal.

The LOFCLEAR Model 128 and 129 Filter Bags were especially developed for the filtration of electro-coatings in the automotive industry. The filtration design allows pigments to pass through the filtration layers, while retaining impurities and removing silicones and other crater forming substances. The LOFCLEAR 130 Filter Bag add extra adsorption capacity for retaining high amounts of oils or other crater forming substances. The LOFCLEAR 135 Filter Bag delivers high removal of particulate and oils for clearcoat applications where pigment removal is not an issue.

LOFCLEAR Series 500 Filter Bags

LOFCLEAR Series 500 Filter Bags have an all welded multi-pleated construction for high efficiency and long life. This series of bags has a pleated prefiltration layer and a complex design of final filtration layers allowing the removal of difficult to filter gels and deformable particles withy a high capacity of solids loading. The outer web covering eliminates any downstream fiber migration.

LOFCLEAR Series 500 Filter Bags are available in four different efficiency ratings so you can choose your exact required filtration efficiency. LOFCLEAR Filter Bags have filtration efficiencies from 95 to 99% with dirt holding capacity of over 2 pounds.

Among the many applications of LOFCLEAR Series 500 Filter Bags are oils, slurries, dilute oil removal, recirculation batch systems and systems with heavy contamination.

HAYFLOW Filter Elements…The Best of Both Bag and Cartridge Filtration

FEATURES

• High flow rates – smaller vessels can be used.
• Five times greater life than a filter bag.
• Retains 75% less liquid than a filter bag.
• Easy retro-fit to existing vessels

The best of both bag and cartridge filters in one revolutionary new filter element.

Take advantage of the best of both bag and cartridge filtration with the HAYFLOW™ Filter Element, a new development in filtration technology from Eaton. Usually bag filters are larger than cartridge filters but easier to handle and more cost effective. Now Eaton’s design brings the best of both systems together…high flow rates in compact vessels or a longer lifetime and extended media changing cycles in standard size vessels…all at a reduced cost.

With up to 70% greater surface area than a standard filter bag, filtration system operators and designers can enjoy reduced operating costs using HAYFLOW elements with existing, standard size vessels. Because of the high flow rates possible with HAYFLOW elements, it’s also possible to reduce the size of the filter vessels in new systems by up to 50% thus lowering the initial cost. HAYFLOW elements gives you a choice…lower operating costs or lower initial system cost.

The combination of highly efficient filter media, enlarged surface area, better dirt-holding capabilities and a reduction of the residual liquid volume retained in the element are all compelling reasons to consider HAYFLOW for your filtration applications.

Operator Friendly Design

System operators like HAYFLOW elements because in many applications changing a HAYFLOW element is easier than changing a filter bag. That’s because the HAYFLOW element only retains 25% of the residual liquid volume of a similarly sized filter bag. This means the HAYFLOW element can weigh up to 75% less than a filter bag. Since a full bag can weigh up to 33 pounds this is an important consideration for the system operator. And this lower retention volume means less saleable product has to be discarded with each filter media change and disposal costs are reduced as well.

Application Versatility

Standard HAYFLOW filter elements are available in both polypropylene and polyester extended life needle felt media with a SENTINEL sealing ring. These two materials are very versatile and will perform well in a majority of applications over a wide range of temperatures. For special applications HAYFLOW elements are available with other media choices. Basically, any weldable filtration media can be use to construct a HAYFLOW element for your application. Multi-layered construction is also possible for applications that require it. Using melt-blown polypropylene media, HAYFLOW elements are available with high micron retention ratings, and with selective absorption characteristics as well.

It’s Easy to Change to HAYFLOW Filter Elements

Changing over from ordinary bag filtration to HAYFLOW filtration couldn’t be easier. No new filter vessel is required. Existing vessels need only to be fitted with a new HAYFLOW restrainer basket for instant compatibility. No tools, special equipment or modification to the vessel is required. Just drop in the new basket and you are ready to take advantage of all the benefits offered by HAYFLOW filter elements.

How the HAYFLOW Element Works

The heart of a HAYFLOW filter element is two concentric cylinders of high quality extended life Eaton filter media that are formed using unique fabric welding technology to create a no by-pass seam. The diameter of the cylinder is the same size as a standard filter bag so retrofitting into existing systems is easy. The element features Eaton’s SENTINEL® sealing ring for a positive seal. The process fluid enters the inside of the element, passes through it, and exits through the vessel outlet. The filtered out material stays inside the HAYFLOW element, not on the outside like a filter cartridge, for easy change out. 

LOFCLEAR™ Oil Removal Polypropylene Meltblown with SENTINEL™ Ring

The LOFCLEAR™ oil removal filter bags were developed for the filtration of coatings in the automotive industry. The filtration design allows pigments to pass through the filtration layers, while retaining impurities and removing silicone oil and other crater forming substances.

• The LCR-118/128 are designed for e-coat applications at flow rates no higher than 45 gpm/size 01 and 90 gpm/size 02.
• The LCR-119/129 are designed for e-coat applications with higher flow rates up to 60 gpm/size 01 and 120 gpm/size 02.
• The LCR-130 extended life bags are designed for extra adsorption capacity and high amounts of oil at 90 gpm/size 02.
• The LCR-135 bags deliver high removal particulate and oils from clear coat where pigment removal is not an issue, flow-rate 30 gpm/size 02.

Eaton’s premium filter bags must be assembled with a matching bag positioner and supported by an original Eaton Filtration round bottom Restrainer Basket. A special basket without the internal bead is recommended for a better fit and extraction of the filter bag.

The Eaton Oil Adsorption Insert is the ultimate solution for increased oil removal capacity. It is made of meltblown polypropylene with a spun bound cover and a polypropylene extruded core for support. The insert can be installed in most standard size 02 filter bags with SNAP-RING and SENTINEL ring collars. This insert increases dirt and oil removal capacity. It is necessary to equip these inserts with a stainless steel cover plate for optimal efficiency and capacity.

Welded Construction Filter Bags

Now, applications requiring polypropylene or polyester felt filter bags can take advantage of the all-welded construction afforded by Eaton SENTINEL® Filter Bags. These bags, made from silicone free materials feature super-strong welded construction rather than sewn seams. This construction ensures that nothing by-passes the filtration media through holes in sewn fabric.
SENTINEL® Seal Ring

All SENTINEL® Filter Bags utilize the SENTINEL® seal. It’s all plastic, polypropylene, polyester or Santoprene® construction, provides a flexible, chemically resistant seal which adapts to any filter housing. This unique design employs a pressure activated sealing lip which responds to increases in differential pressure. As the pressure increases, the seal of the ring improves, insuring by-pass free performance over all ranges of pressure, temperature and micron rating. The elevated bag handles make removal of the bag from the vessel quick and easy. When a SENTINEL® Filter Bag is installed into an Eaton Filtration Housing, the ring snaps into place, holding its position until the housing is closed.

Proprietary Construction Process

A proprietary construction processes produce a reliable, durable filter bag. All seams are fully welded, producing strong, reliable joints with no by-pass or loose sewing thread. Seams are both strong and flexible, allowing the filter bag to conform to the restrainer basket. The seam edges are heat sealed, eliminating possible loose fibers. This results in a filter bag with durable performance for the most demanding applications.

The UNIBAG is offered in three material combinations:

• All polypropylene media and ring construction – chemically compatible in most applications.
• Polyester media and polypropylene ring – economical when Polyester media is required by the application.
• Polyester media and ring construction – the choice in higher temperature applications.
