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

这种过滤器用于各种流体处理系统中，以去除杂质并保护系统的组件。这种过滤器通常被称为：
粗过滤器：
粗过滤器设计用于从流体中去除较大的颗粒。它通常是过滤的第一阶段，用于保护下游组件免受大污染物的影响。粗过滤器具有相对较高的孔隙率，允许大量流体通过。
目的：它们用于从流体中去除较大的污染物，以防止下游设备损坏或堵塞。它们在水处理系统、工业过程和HVAC系统中很常见。
篮式过滤器：
篮式过滤器是一种过滤器，其中流体通过穿孔篮或网状衬里。当流体流过时，篮子捕获并容纳杂质。它们以设计简单和易于维护而闻名；篮子可以很容易地拆卸、清洁或更换。
目的：它们被广泛用于从液体中去除固体杂质。它们通常用于管道中，以保护泵、阀门和其他设备。篮式过滤器用途广泛，可用于各种流体类型和粘度。
泵保护过滤器：
泵保护过滤器，也称为泵过滤器或吸滤器，是一种放置在泵入口处的过滤器。它的主要作用是保护泵免受可能造成损坏的外来颗粒的影响。
目的：这些过滤器对于保护泵免受诸如沙子、岩石或其他大颗粒等碎片的损坏至关重要。通过防止大颗粒进入泵，这些过滤器有助于延长泵的使用寿命并保持其效率。
所有这些过滤器，尽管它们在设计和应用上可能不同，但其基本目的是从流体中去除杂质。它们是各种系统中的关键部件，可以保护设备免受污染物的损坏，有助于延长设备的使用寿命，并确保通过的流体具有一定的清洁度。它们对于保持流体处理系统的高效和安全运行是不可或缺的。
