Experience purity in every drop with Our Filtration Products: Where Clean Water Begins.
Melt Blown Cartridge Filter
The melt blown cartridge filters are sturdy with a fixed pore structure. The process fluids travel through the medium in a straight path and may encounter up to eight impingements on the way.
String Wound Cartridge Filter
The string wound filter cartridge is woven to form a gradient density – tighter at the core and lighter on the outside.
How Is A Melt Blown Cartridge Filter Made?
The melt blown cartridge filters are cylindrical cartridges made from the finest polymer fibers melt blown and collected over a rotating spindle. The polymer travels through a tubular path and is blown out through the opening and the polymer steam is air dragged to form fibers. These fibers are collected on the rotating spindle to form a gradient structure and then pressed and sintered. This process of blowing fibers, rotating spindle and spinning a cartridge filter is engineered, and cartridges are spun in a controlled environment for the desired quality and variant. The fibers are spun in such a fashion that they form a density gradient, higher at the core and sparse at the outer. The most common material used to manufacture a melt blown filter is polypropylene. Very fine filter medium can filter finer/very small sediments from liquids.
The melt blown cartridge filter is also known as/referred to as spun cartridge filter or spun bonded cartridge filter.
How Does A Melt Blown Cartridge Filter Work?
The filtration in melt blown cartridge filters happens “out to in”. i.e the filtration liquid flows in from the outside through the filter medium (melt blown filter cartridge) into the hollow center and is thrusted out from the outlet. The melt blown filters are available in porosities ranging from 1 micron to 50 microns.
Characteristics Of A Melt Blown Cartridge Filter
The melt blown cartridge filters are sturdy with a fixed pore structure. The process fluids travel through the medium in a straight path and may encounter up to eight impingements on the way. The cartridge filters are widely is used in applications involving water filtration, RO pre filtration, Oils, Filtration of slightly corrosive liquids, compatible solvents and gasses. The spun cartridge filter can filter in operating temperatures up to nearly 80 Deg C.

What Is A String Wound Cartridge Filter?
String wound filter cartridge is a type of depth cartridge filter that is made by weaving yarn around a core. Microfibers are twisted and twined together to form a yarn. This yarn is woven in a honeycomb-shaped weave around the core such that it forms a gradient structure to allow better filtration. The quality of a wound filter cartridge hugely depends on the type of yarn that is used to make the filter. The material of the core and a controlled manufacturing mechanism that produces a precise micron rating also contribute. One should bear in mind the filtration application and other involved physical and chemical parameters before choosing a string wound filter cartridge.
How Does A String Wound Cartridge Filter Work?
The string wound filter cartridge is woven to form a gradient density – tighter at the core and lighter on the outside. This means that bigger sediments are filtered out at the onset, and as the liquid passes through the medium, the finer particles get gradually filtered out at every layer. The winding pattern and controlled thickness of the cartridge results in higher dirt holding capacity and increases the life and efficiency of the filter.
Filter Media
String wound filters, however, are created by wrapping a piece of string around a core, resulting in a tight, dense filter matrix. Cotton, polyester, and polypropylene are some of the materials that can be used to make the thread.
Filtration Efficiency
String wound filters, on the other hand, are better adapted for removing larger particles and sediment and are less effective at capturing tiny particles.
Dirt-Holding Capacity
String wound filters have a great dirt-holding capability. This is because the string used in string wound filters produces a denser matrix with bigger void spaces than fine fibers used in melt blown filters. Because of the bigger void spaces, string wound filters can collect much dirt before needing to be replaced.
Cost
The string wound filter manufacturing process is more straightforward and less costly than the melt blown filter manufacturing process. String wound filter materials are usually less expensive than melt blown filter materials, lowering the cost of string wound filters even further.
Applications
String wound filters are better suited to applications requiring high dirt-holding capacity, such as those in the industrial, agricultural, and municipal water treatment sectors. String wound filters are excellent at removing larger particles and sediment from fluids, making them ideal for well water filtering, irrigation, and industrial fluids.
Filter Media
Melt blown filters are created by melting and extruding thermoplastic resin into a fibrous matrix and blowing it onto a revolving core. The resulting fine fiber matrix is shaped into a filtration cartridge.
Filtration Efficiency
Melt blown filters have a higher filtration efficiency than string wound filters in general, particularly when it comes to capturing smaller particles. Because fine fibers in melt blown filters produce a denser matrix with more surface area for particles to adhere to, the capture rate is higher.
Melt blown filters are highly efficient at removing fine particles from fluids because they can capture particles as small as 0.3 microns in diameter.

Dirt-Holding Capacity
In contrast, melt blown filters have fibers that were blown onto the core as a hot liquid polypropylene and as the fibers cool, they are fixed in place. These fibers are not movable and allow the melt blown to collect dirt more uniformly throughout the filter. Dirt holding capacity comparisons between the melt blown and string wound vary based on applications.
Cost
The cost of melt blown and string wound filters vary based on factors such as filter size, the material used, and the manufacturer. Cost comparisons in the past have put string wound filters at a lower price point, but due to advancements in melt blown technology the price gap is minimal.
Applications
Melt blown and string wound filters are used in various applications but are usually better suited for specific filtration requirements.
Melt blown filters are commonly used in uses requiring high-efficiency filtration. They are frequently used in pre-filters for reverse osmosis (RO) and chemical filtration applications because polypropylene is compatible with many chemical fluids.
