What is a filter or industrial filter is one of the widely used equipment in various industries. This filter prevents the movement of suspended solid particles in different fluids such as liquids and gases. In general, there are two types of filters for use in industries. One is filters that perform the filtering action when the fluid is moving, and the other type performs filtration when the fluid stops moving.
Different types of industrial filters are used for different fluids. Even each of the fluids, whether in liquid or gas state, have different physical and chemical properties, and their screening requires different filters. Based on this, air filters, oil filters, filter pads, nano filters, dry air filters, honeycomb filters, glass fiber filters, etc. They are available in the market for different applications.
High-quality filter features
Industrial filters must be designed in such a way that, in addition to preventing the passage of solid materials in the fluid, they can also purify the remaining solution. For this reason, filters have the following features.
to separate and screen the filter, the membrane and the filter shell have the main role and it is necessary to design them in the best possible way and use the best possible material for their production so that in addition to separating the solids, the filter has a longer shelf life.
At the time of design, a suitable filter, especially in the membrane and shell parts, should be designed in such a way that with the passage of time and the accumulation of separated solids, the filter does not get blocked and blocked.
Inevitably, over time, even the best filters with the ability to remove blockages will need cleaning and removal of contaminants and solids.
The filter shell is one of the most important parts of the filter that separates solids from fluids. If the separated solids are corrosive, an industrial filter is necessary to be able to resist corrosion.
What is the use of the filter
Filters are used in oil and gas and petrochemical industries, automobile manufacturing, and all industries that produce pollutants and must be purified.
Filters are also used in the paint industry. Filters are designed according to the type of fluids and impurities present in them.

It should be mentioned that in the cases of using these filters to separate solid particles from gas, samples should be used that are suitable for the working environment and provide a good level of efficiency.
Filter rose fibers and consumables
Different raw materials are used in the production of these filters according to the characteristics of the filter environment in terms of the size of the suspended particles and the ambient temperature, as well as the volume of air passing through the filter surface and the desired efficiency level.
Synthetic fibers are considered the most important primary material in this sector, which in turn includes a wide range of fibers. These fibers are used both in the production of the non-woven layer of the non-woven textile media filter and for improving the physical properties and mechanical resistance. The final product is used in the upper part of the filter screen. The main fibers used in this sector are:
- Polyester (PES)
- Nylon (NY)
- Polypropylene (PP)
- Meta Aramid (M-Aramid)
- Para-Aramid (P-Aramid)
- Meta acrylic (M-Arcylic)
- Graphite fibers
- Steel fibers (Metal fibers)
- Polyacrylonitrile (PAN)
- Anti-static fibers
- Polyimide
- (PPS)
Additional operation and modification of the media rose filter surface
Considering the various applications of filters and the polluted environment’s characteristics in terms of chemicals, temperature, humidity, and the type of suspended particles, various additional operations are carried out on the media filter. Rose Filter Company uses trained people and equipped laboratories to provide this possibility It enables users to propose products with a longer life cycle and better efficiency by choosing the correct and cost-effective finishing operations.

Resistance properties of used fibers
The fibers used in the production of these types of filters can be divided into four groups based on the molecular chain structure and thermal resistance:
- Suitable fibers for ambient temperature can be used in a temperature range below 60 degrees Celsius.
Fibers suitable for medium temperatures, these fibers are among the most used raw materials in the production of gas and liquid filters and are used at temperatures up to 130 degrees Celsius.
- Suitable fibers for high temperatures can be used up to 200 degrees Celsius.
- Fibers suitable for very high temperatures, these fibers are used for temperatures above 200 degrees Celsius. The most important feature of this group of fibers is their very resistant molecular structure.
In addition to paying attention to the thermal resistance of the fibers, consumption of other physical and chemical characteristics such as the amount of air penetration in the fabric, resistance to acidic and alkaline environments, abrasion resistance, resistance to tearing, layering, product resistance to the effects of hydrolysis and oxidation, resistance to wet environments, reaction Against solvents, chips of molten metals, etc. should also be considered more than the consumption of fibers.
Tests and quality control and assurance systems
To control and guarantee the quality of the filters produced in the industrial sector, numerous tests are carried out at different stages of production from the semi-finished product to the final product. In some cases, these tests are also applied to the product installed at the place of consumption. It is based on internationally specified guidelines and methods.
This operation is carried out by expert and experienced staff with up-to-date knowledge and technical knowledge using reliable and advanced laboratory equipment. High accuracy and continuity in conducting tests on raw materials, control of semi-finished materials, and ultimately guaranteeing the quality of the final product are important principles in this part of Nagin Rose Industries, in order, to assure users of the recorded results of the tests and their analysis at their disposal is placed
