Filter Type W is a very economical strainer:
Its pressure loss is only 50% in comparison to conventional pot / basket strainers and only 25% in comparison to Y-Filters of same dimension and sieve mesh.
This advantage reduces the cost of pump energy and result in extended reserves until the cleaning cycle. Connectors for the differential pressure are standard from size DN 150 and above (below upon request possible).
The streamlined angle of impact between the flow and the sieve / screen results in a slowly increasing pressure loss, caused by dirt, and at least more than double the operational time before cleaning.
As the cleaning cover is located at the top, the rare cleaning cycle is easily and conveniently carried out. The sieve is a closed basket and simultaneously serves the complete removal of the dirt – hence the remaining medium is already cleaned and can be just drained.
Traditional pot or basket strainers are limited by their horizontal installation in pipelines.
In the past, the option to utilise a strainer also in vertical mounting was only provided by Y-Filters – with its given disadvantages of high flow resistance and inconvenient handling of the cover for removal of the sieve (net weight of the cover, overhead work).
The Filter Type W, however, can be installed in both ways – with its given advantages in regards to minimal pressure losses and low frequency of maintenance.
In addition, equipping the Filter Type W with swivel (horizontal) or swing arm (vertikal) provides the maintenance personnel easier handling of the cover and a crane-independent removal of the sieve – with the dirt for cleaning.

Designed for: hydraulic
Filtration element: basket, strainer
Other characteristics: W
Operating pressure: Min.: 16 bar (232.06psi) / Max.: 100 bar (1450.38psi)

Strainers in pipelines have the following function:
Preventing faults and avoiding damaging of existing plant components;
Cleaning of the flowing medium.
These two primary tasks are valid in all areas of application – regardless whether the media are:

• Hot water (district heating systems)
• Cold water (Cooling Systems, municipal applications)
• Hydrocarbons (pumping of oil, petroleum, LNG/LPG)
• Acids or alkalis (chemical plants).

Generally, these tasks are fulfilled by all commercially available filter types, however with high energy requirement and frequent maintenance intervals. Additional cost for shutdown and cleaning could also be reduced.

Overall analysis and solution approach
Minimum €500 Mio. additional cost of pump energy arise in German plants every year!
The reason for this is the installation of common strainers with respective high flow resistance figures (ζ = 3 ... 7 and higher).
The Filter Type W offers with its ζ = 0.7 - 2.3 the solution:
efficient + effective= economical

這種過濾器用於各種流體處理係統中，以去除雜質並保護係統的組件。這種過濾器通常被稱為：
粗過濾器：
粗過濾器設計用於從流體中去除較大的顆粒。它通常是過濾的第一階段，用於保護下遊組件免受大汙染物的影響。粗過濾器具有相對較高的孔隙率，允許大量流體通過。
目的：它們用於從流體中去除較大的汙染物，以防止下遊設備損壞或堵塞。它們在水處理係統、工業過程和HVAC係統中很常見。
籃式過濾器：
籃式過濾器是一種過濾器，其中流體通過穿孔籃或網狀襯裏。當流體流過時，籃子捕獲並容納雜質。它們以設計簡單和易於維護而聞名；籃子可以很容易地拆卸、清潔或更換。
目的：它們被廣泛用於從液體中去除固體雜質。它們通常用於管道中，以保護泵、閥門和其他設備。籃式過濾器用途廣泛，可用於各種流體類型和粘度。
泵保護過濾器：
泵保護過濾器，也稱為泵過濾器或吸濾器，是一種放置在泵入口處的過濾器。它的主要作用是保護泵免受可能造成損壞的外來顆粒的影響。
目的：這些過濾器對於保護泵免受諸如沙子、岩石或其他大顆粒等碎片的損壞至關重要。通過防止大顆粒進入泵，這些過濾器有助於延長泵的使用壽命並保持其效率。
所有這些過濾器，盡管它們在設計和應用上可能不同，但其基本目的是從流體中去除雜質。它們是各種係統中的關鍵部件，可以保護設備免受汙染物的損壞，有助於延長設備的使用壽命，並確保通過的流體具有一定的清潔度。它們對於保持流體處理係統的高效和安全運行是不可或缺的。
