ARGO HYTOS made it once again! The market-acclaimed filter element series EXAPOR®MAX 2 has been improved significantly once again. Soon the successor, the new filter element generation EXAPOR®MAX 3, will be launched on the market. At the Hannover Messe in April, particularly interested customers will already have the opportunity to see and inspect prototypes of this new filter element series and to obtain information in advance on their individual application in advance.

The new development of this premium filter element series mainly focused on the further improvement of technical performance data such as pressure loss and dirt holding capacity, but also on the redesign of the optical appearance with the printing of the new label system according to customer requirements.

Performance data
The new EXAPOR®MAX 3 filter element generation drastically improves the standards that have been set to date in the areas of pressure loss, dirt holding capacity and flow fatigue resistance. In doing so, the power density of a filter element significantly further increased. As a result, it will now be possible to switch far more frequently to smaller filter elements in the same application, thus saving costs and installation space at the customer’s. The new series will be available in the finenesses 5 µm, 10 µm and 16 µm.

Dirt holding capacity

The absolute dirt holding capacity and thus the service life could be further increased. This is due to a significantly improved specific dirt holding capacity from approx. 14 mg/cm² to >16 mg/cm².

This means an increase of impressive 15%. The benefits for the customer are obvious with a significantly improved service life and the resulting longer machine availability. The central question is: How was such an improvement possible?
Answer: Due to a new filter element bellows structure which was developed based on experience, simulatory design, as well as the use of extensive supplier know-how.

The exact coordination of the individual filter materials plays a decisive role. For the first time, the newly developed filter bellows structures also use nonwoven materials with a multi-phase structure or so-called gradient structure. This involves a multiple gradation of the fineness in the filter bellows structure, which is not limited to the number of material layers. This prevents premature blocking of individual layers and ensures more uniform and above all better utilization of all nonwoven materials. This new, precise coordination of the individual layers leads to the aforementioned greatly improved dirt holding capacities and the associated longer service life in the customer application.

Pressure drop / flow fatigue strength
The precise matching of the new nonwoven materials to the well-proven hybrid supporting fabric used in the predecessor series also leads to a further significant reduction in pressure loss of more than 20%. This hybrid support fabric has plastic wires in the load areas instead of normally used stainless steel wires and a special weaving technique. The advantages of this fabric, such as the excellent pleat channel formation for pressure loss optimization and the very good flow fatigue strength, are thus also guaranteed in the new filter element generation. Wire breaks during alternating loads (e.g. volume flow changes) in the later customer application, as they occur with pure stainless steel meshes, are therefore no longer an issue with the new premium EXAPOR®MAX 3 series. The advantage over replica elements from various competitors equipped with pure steel fabrics is clearly evident.

Variety of variants / individualization
As usual with ARGO-HYTOS, the variety of variants, also with the new premium series, is given. It makes no difference whether the desired size is a small filter element for a steering gear application or a large filter element for an injection-molding machine. Standard catalog version or individual sizes precisely matched to the installation space: a wide range of products is available. Extensive empirical tests carried out at ARGO-HYTOS on various element sizes confirmed the high expectations placed on the new EXAPOR®MAX 3 filter element series and established a very good database for the planned start of series production. Even before the official start of series production, individual, customer-specific designs can be supplied with a high degree of reliability. A simple inquiry is sufficient.

Optical appearance, customer logo
In addition to the technical performance improvements, the optical appearance and thus the outer label area that can be designed and determined by the customer were also improved and their possibilities greatly expanded. With the help of a new printing technology, full-surface, colored imprints can now be realized at any time on customer request. There will only be restrictions in the print image for very small characters or details. In general, almost anything is possible with the new technology and this in a very good print quality and color strength. In addition to the customer logo and type designation, also operating conditions or installation instructions can be displayed on the label surface. An additional great added value for the customer which in the past was frequently asked for but could unfortunately not be served at this time.
