You will not need to replace or fix them as much.
A filter bag is a tool that helps take out unwanted stuff from liquids or air. People use it in many places to keep things clean and machines working right. The filter bag lets liquid or air go through its walls but catches dirt, dust, or other bad things inside. Most filter bags look like a tube or a pocket and fit inside a filter holder. You can find them in water plants, food factories, and chemical plants.
A filter bag is built to be strong. Sometimes it has a mesh basket inside to help, especially when there is a lot of pressure. The liquid or air usually moves from the outside of the bag to the inside. This way, the bag catches the bad stuff and keeps it from getting out. The table below shows what makes a filter bag special:
Feature | Description |
|---|---|
Definition | A device for filtration, made of a bag-shaped filter medium. |
Construction | Made from woven or nonwoven materials, sometimes with a support basket. |
Operation | Fluid flows from outside to inside, trapping contaminants inside the bag. |
Applications | Used in chemicals, food, coolants, cleaning fluids, paints, and varnishes. |
Materials | Polypropylene, polyester, nylon, and other advanced fibers. |
Formats | Mesh, single layer, multilayer, pleated, and graded pore types. |
LOONG FILTRATION makes filter bags that are strong and last a long time. You can pick from different ways the bag is put together, like ultrasonic welding, sewing, or full welding. Ultrasonic welding and full welding make the bag hold together without any seams. This means the bag will not leak or break easily. These ways also mean you do not need thread or glue, so nothing extra gets into your product.
You can choose different kinds of filter bags for what you need. There are two main kinds: depth filtration and surface filtration. Depth filtration uses thick stuff, like needle felt, to catch dirt all through the bag. Surface filtration uses a mesh, like monofilament, to catch dirt on the outside.
The material you pick for your filter bag is important. Each one is good for different things. Here is a table to show you the most common materials and what they are used for:
Material | Advantages | Applications |
|---|---|---|
Polypropylene | Chemical resistance, lightweight, cost-effective | Chemical processing, food & beverage, cleanup |
Polyester | Strong, UV resistant, durable | Automotive, aerospace, wastewater |
Nylon | High strength, abrasion resistance | Water treatment, chemical processing |
Nomex | Heat stable, chemical resistant | Food, beverage, pharmaceuticals |
PTFE & PVDF | Top chemical resistance, non-stick | Semiconductors, high temperature |
When you use a LOONG FILTRATION filter bag, you can pick needle felt for depth filtration or monofilament mesh for surface filtration. Polypropylene is good for chemicals, and polyester works well with heat and tough jobs. You can match the filter bag to your job, whether you need to filter hot liquids, strong chemicals, or tiny bits.
Tip: Always check if your filter bag materials are certified. LOONG FILTRATION uses SGS and FDA certified materials. This means the filter bag is safe for food, medicine, and other important products.
You also want to keep your process clean. LOONG FILTRATION puts each filter bag in a cleanroom. This keeps out dust and dirt, so only the filter bag touches your product. You can trust your filter system to work well and keep your products safe.
A filter bag helps take out unwanted bits from liquids or gases in factories. First, the fluid goes into the filter housing. Then, it moves through the filter bag. The bag acts like a wall with tiny holes. These holes let clean fluid go through but catch dirt, dust, sand, and rust. This keeps machines safe and products clean.
There are two main ways a filter bag works:
Depth filtration: The bag has thick layers. Big particles get stuck near the top. Smaller ones go deeper and get trapped inside. This type holds more dirt and is good for dirty fluids.
Surface filtration: The bag uses a thin mesh. Dirt stays on the outside and forms a layer called a "filter cake." This layer can help catch even smaller bits as it grows.
A filter bag can catch very tiny or bigger particles. You can use it for fast-moving fluids and large amounts. This makes it great for many factory jobs.
Tip: Always pick a filter bag with the right micron rating. This helps you remove the right size particles and get the best results.
You want your filter bag to catch every bit of dirt. It should not let any fluid leak around the edges. LOONG FILTRATION uses a special zero-bypass sealing system to stop leaks.
Here is how the zero-bypass sealing system works:
Feature | Description |
|---|---|
Reliable Seal | A strong flange makes sure all fluid goes through the filter bag. No fluid can slip past the sides. |
Zero Bypass | Ultrasonic or heat seals join the bag’s layers without holes or gaps. This stops leaks and keeps fibers from getting into your product. |
This design keeps your filter system safe and working well. The filter bag catches all the dirt, so nothing bad gets into your final product. This is very important for food, chemicals, and car paint, where even a small leak can cause big problems.
Note: LOONG FILTRATION uses special welding and certified materials. This means your filter bag will not leak and will always keep your products safe and pure.
A filter bag with zero-bypass sealing helps you feel sure. You know your filter system is working right and keeping your machines and products safe every time.
You want your filtration system to work well every time. Bag filters catch almost all unwanted particles, so they are very efficient. Most bag filters in factories can remove about 94% to 98% of contaminants. Some special bag filters can even remove up to 99.9%. This means your liquids are cleaner and your products are safer.
The chart shows that bag filters work better than many other filters. Using a filter bag helps protect machines and keeps everything running smoothly. It also lowers the chance of machines breaking down.
Bag filters are reliable and work in many places, like food, chemical, and car factories. They remove dirt, sand, and other bad things. If you pick the right filter bag, your system will last longer and work better. Changing the filter bag on time and checking it often keeps your system safe and strong.
Bag filters help you save money in different ways. They can clean a lot of liquid, from 90 to 2,400 gallons each minute. This makes them good for big jobs. You do not need to buy or change bag filters as often as other filters. Bag filters usually last longer, so you save money.
Here are some reasons why bag filters are a smart choice:
They cost less at first than cartridge filters.
They last longer if you use them right.
