Here’s what you need to know about the different uses of filter bags and how you can choose the best that suits your product.

Filtration is mandatory if you are investing in production industries. When you buy felt filter bags, they play an essential role in the quality of your final product.

Its application includes those who deal with food processing, cooling systems, paint manufacturing industries, lubricants, and other kinds of water-based liquids. Filtration helps reduce the severity of contamination agents on equipment by retaining their original quality. The damage can be minimised if you buy felt filter bags.

How to Choose the Right Filter

Firstly, consider the type of product that is in need of a filtration bag and its features.

Secondly, select the right viscosity of the filtration bag depending on the type of product you are handling.

Thirdly, check the flow rate and measure whether it is the best for your product.

Fourthly, ensure that the filtration bag can maintain an average temperature that is not damaging to the product.

Lastly, compare the particle size with the diameter of the filtration bag. If it happens to pass through, choose a pack that best suits the debris to be filtered.

Filters vary in sizes and they are classified as follows:

The Micron Rating Filters

This type of filter has a length of about a one-millionth meter. It is a tiny size. For comparison’s sake, it ranges between 40-90 microns as human hair and the particle size is below 25 microns, which is not visible. Bear in mind that filtration efficiency is
profoundly affected by conditions such as pressure and the level of contamination.

Size 5 Micron

It is a filter that sieves massive amounts of particles from fluids. It is even possible to go below the minimal one-half rating of a micron. They are disadvantageous mainly because they quickly get blockage issues. Five rated micron filters work in the food and drink
processing industries.

Size 10 Micron

These can filter anything unseen from any liquid apart from viruses and bacteria. It is still a minimal filter, but it is beneficial to many industries, ranging from oil manufacturing to chemical plants since it can filter. They tend to clog faster than the size 5-micron filter.

Size 25 Micron

This type can filter anything more significant than a white blood cell. They are best suited for industries that process products hence they can sieve tiny debris and don’t clog despite the particle size. They are more effective when you combine them with various filters.

Size 50 Micron

It is ideal to use when you want to balance filtration and blockage. They sieve debris, which is only visible by the human eye and the size close to the diameter of a human hair and even more extensive. The merit that stands out is that this filter can sieve so much debris from fluids and never face clogging problems prone to the micro-rated filters. Its versatility is best suited in most industries.

Classification of Filters

The Felt Type

Firstly, it is available at affordable prices and offers perfect filtration. The dense nature it has is permeable to hold colossal amounts of dirt. Their demerit is that once used, cannot be reused. Those ranging from 1-200 micron grades are Needlefelt media, while those that are at the range of 1-25 micron offers high efficiency.

The Mesh Type

Their surface covers 1-1500 micron are ideal for large debris. It is easy to clean them. There are two types of mesh filters. The mesh filter built with many small filaments rolled together, and later knit is referred to as Multifilament, whereas the type built-in a precise manner knit in single threads is called Monofilament. It is expensive compared to other filter materials since it is sturdy and durable.

Felt filter containers raw materials are polyester or polypropene. The polyester types are suitable at temperatures reaching 275 degrees Fahrenheit and contain microns as high as 500.

The Best Quality Filters

Microfiber packs integrate melt felt medium surfaces with a quick-dry surface to produce maximum filtration performance at low scores of 1-50 microns.

Polypropylene “500 Group” cleaners use various layers of polypropylene microfiber to produce up to 99 percent absolute efficiency at 1-32 micron levels.

Filter Construction

Sewn seam products are the cheapest filter containers. As the title indicates, polyester or polypropylene material is used to bind the seams. Welded seam containers have heat-welded seams. This design offers much greater seam resilience without creases or the ability to override unfiltered fluid via the syringe perforations contained on traditional woven bags. These bags have rings/flanges of zinc alloy, steel, or titanium.
