4. Wound Liquid Cartridges

Name: Wound filters
Description:
Design principal: fibers are wound with a diagonal pattern onto a core without using any binding material. This welding feature not only physically strengthens the overall structure but also creates passageways within which filtration process also takes place as it does on the surface. This double path process brings the following advantages:
No surface caking
Lower pressure drop
Longer filter life
Chemical compatibility in most applications
Particles, when penetrating into the filtering medium through the diagonal gates, are trapped by the tortuous path of fibers. The liquid flow is from the outside into the center so that the larger particles are retained on or near the surface and the micron rated particles are trapped within the layers, The amount of the retained particles is strongly dependent on particle size, particle type, solution and the pressure development by the pump. Wound depth cartridges operate at lower flow rates compared to pleated filters
Filtering media: Cotton, polypropylene, glass fiber (heat-cured to prevent fiber migration),viscose, nylon or polyester media are selected for efficient filtering. Particle size to be retained may vary within a range of 0.5µ-200µ depending on the medium and cartridge size.
Core material:polyproplene,304 or 316 low carbon stainless or tinned still is used in core production depending on the liquid or gas to be filtered. Inner diameter of the core is 28mm.
Application fields: Food and beverage , chemicals , electronics, photograph technology, hospitals, magnetic coatings, plating, oil production, pharmaceuticals industry, cosmetics, paint, ink, sea water, household and municipal water, various gases.
