Pullner Expands String Wound Filter Cartridges for Industrial Filtration Applications

Pullner, a provider of OEM/ODM filtration solutions, has highlighted the benefits of string wound filter cartridges for industrial filtration applications. The company supplies filtration equipment to industries including microelectronics, petrochemical processing, power generation, pharmaceuticals, food and beverage, desalination, and automotive manufacturing. String wound cartridges are used across several of these sectors, most often at the pre-filtration stage of a process.

These cartridges are made by winding yarn or fiber around a central core in a controlled pattern, creating a depth filtration structure that captures particles of varying sizes as fluid passes through the layers. This design allows for a graded, depth-style structure that is preferred over a surface format such as a pleated cartridge. According to Lucy, Sales Manager at Pullner, string wound cartridges remain a practical option for many industrial filtration applications, particularly where dirt-holding capacity matters more than the finest possible micron rating.

The dirt-holding capacity of string wound cartridges is one of the most common reasons buyers choose this format. Because particles are retained throughout the depth of the cartridge, it can hold more captured material before replacement than some surface formats. This makes the format a frequent choice for pre-filtration, where the main objective is protecting downstream equipment rather than reaching the finest micron rating at that stage.

Pullner manufactures string wound cartridges for both standard applications and custom specifications. Customers can select core material, winding fiber, and dimensions to suit existing housings or new installations. The company's OEM/ODM model allows manufacturers to source cartridges built to specific technical requirements instead of adapting a general-purpose cartridge to a specialized process. For operators running multi-stage systems, string wound cartridges are commonly installed upstream of pleated or membrane cartridges. In this arrangement, the depth stage removes the bulk of the particulate load, which can reduce how often finer and higher-cost filters need replacement further along the line.

Pullner's product range covers high-flow, pleated, string wound, membrane, and stainless steel cartridges alongside matched housings, serving the microelectronics, petrochemical, power generation, pharmaceutical, food and beverage, desalination, and automotive industries. The company continues to expand its offerings to meet the diverse needs of its customers.
