Miami, FL 33166, United States, 14th Oct 2026 – Pullner, a respected provider of OEM/ODM filtration solutions, has announced details of its string wound cartridge range for industrial filtration applications. The range is supplied alongside the company’s high-flow, pleated, membrane and stainless steel filter cartridges and matching filter housings. The announcement is relevant to manufacturers and plant operators that use depth filtration to protect downstream equipment and finer filters from particulate load.
Pullner 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.
How String Wound Cartridges Work
A string wound cartridge is made by winding yarn or fibre around a central core in a controlled pattern. The winding creates a depth filtration structure that captures particles of varying sizes as fluid passes through the layers, rather than only at the outer surface.
Pullner said string wound cartridges are typically specified where a graded, depth-style structure is preferred over a surface format such as a pleated cartridge. The cartridges are available in different materials and wind patterns, selected according to the fluid type and particulate load involved in each application.
Dirt-holding capacity 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.
Material Options and Chemical Compatibility
Core material and outer wrap can be adjusted to meet chemical compatibility requirements, depending on the fluid a cartridge will be exposed to. Winding fibre selection also affects how a cartridge performs with different temperatures, solvents and particulate types.
“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,” said Lucy, Sales Manager at Pullner. “The company works with customers to match the wind pattern and material to the fluid and particulate conditions present in their process.”
Standard and Custom Specifications
Pullner manufactures string wound cartridges for both standard applications and custom specifications. Customers can select core material, winding fibre 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 specialised process. The same customer-specific approach applies across Pullner’s other cartridge types, including its pleated, membrane and stainless steel ranges. Matching filter housings are supplied for each cartridge type, allowing a cartridge and housing to be specified together for a given installation.
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.
“The plan is to continue adding string wound configurations for industrial customers as filtration requirements vary across applications,” said Lucy, Sales Manager at Pullner. “New configurations will be developed in response to the fluid, temperature and housing specifications that customers bring to the company.”
