Air pollution is currently the world’s greatest concern. Based on World Health Organization statistics, in 2012, it is estimated that outdoor air pollution accounted for 3.7 million deaths before their time and 627,000 deaths due to exposure to PM2.5 particles. In any industrial workplace, having the appropriate filtration system removes dangers and unhealthy surroundings. This only leads to increased productivity of employees, lesser cost, and equipment protection from dust, hence minimizing system downtime.

This guide will be discussing the benefits of dust collector filter bags, choosing the right filter for your dust collector, and cleaning your filter bags properly.

Top 6 Benefits of Dust Collector Filter Bags

The following are the six best benefits of dust collector filter bags.

1. Dust bags are used to collect mostly fine, dry, and non-fibrous dust. They can capture dust up to 99.9%. This makes it essential for most dust control activities.
2. Dust bags can be applied in metallurgy, ceramics, chemicals, food processing, machinery manufacturing, and mining sectors.
3. Some of the applications include grinding, packaging, powder handling, sanding, cutting, drilling, mixing, and crushing.
4. The dust bags are also powerful and effective, making removal easy.
5. A good dust bag helps improve the performance of the dust collectors so that the air filtration is improved by any space being cleaner.

How to Choose the Right Bag Filter for Your Dust Collector

Understand Your Facility’s Needs

The first step is to understand the conditions and requirements of your facility. You need to know what the air or gas stream contains and the size and type of particles passing through the filter. This helps you choose the right fabric and design for the filter to suit your industrial environment.

Check Operating Temperatures

The fabric material you select should match the temperature of the gas stream entering the system. The type of dust collector (pulse-jet, shaker, or reverse air) will also affect how dust gets cleaned from the filter.

 

For temperatures below 120°F (50°C), most synthetic or natural fibers will work. But for higher temperatures, you need heat-resistant materials like PVC, nylon, cotton, polypropylene, PTFE, fiberglass, or Polyimide.

Consider Material Properties

It’s important to know how much heat the material can handle. For example, cotton can resist heat up to 180°F (85°C), polyester up to 300°F (150°C), and PTFE up to 500°F (260°C). If there’s moisture or chemical fumes in the gas stream, this also affects your choice of material.

Choose the Right Filter Design

The design of the filter depends on how well the dust collector works. Some systems use woven fabrics, while others need non-woven fabrics like needled felt. Pulse Jet systems allow for thicker, denser filters, while shaker systems work best with lighter fabrics. Reverse air systems, which are used when filtration needs are lower, use flexible, lightweight woven fabric.

How Are Filter Bags in Dust Collectors Cleaned?

So now, a question comes to your mind: ‘How to Clean Dust Collector Filter Bags?’ Don’t worry, we’ve got you covered.

One of the widely used techniques for cleaning filter bags is compressed air. Compressed air expels air into these filter bags, which knocks off the dust from the outer surface. Another method uses lower energy and involves using fans positioned above the filter bags. These fans blow air in reverse to clean up the bags in cycles.

You can clean the bags by shaking them as well. Bags are applied onto a frame, and when it shakes, dust falls off.

Cleaning the filter bags regularly is absolutely important to ensure that the dust collector will work properly and for a long time. But, how often you clean depends on plenty of factors, such as moisture in the air, type and amount of the dust, and operating temperature.

3 Reasons to Replace Your Dust Collector Filter Bags

You should replace your dust collector filter bags in these three situations:

1. The Filter is Damaged: A damaged filter will allow dust and particles to move through, otherwise causing clogs within your equipment and increases the safety risks. Internal pressure drops rapidly when the filter is damaged.
2. The Filter Has Reached the End of Its Life: When the filter becomes overloaded with dust, it’s time to replace it. Different filters have different lifespans based on their material and operating conditions.
3. The Filter is the Wrong Size or Type: Using an incorrect filter can create more dust and increase the risk of fires. Replace it immediately if it doesn’t fit your needs.

How to Choose the Best Filter Bags

Whether you’re looking for industrial dust collector bags, filter bags, or filter sleeves, it’s important to find a reliable manufacturer and supplier. Wxfiltercloth is a well-known name in this field. Our company offers a range of fabrics, from lightweight to heavy-duty, for both solid and liquid filtration needs.

Conclusion

Overall, dust collector filter bags are highly important for the health & safety of the users. They remove dust effectively, ensure good air quality and protect the equipment resources from dust, enabling smooth operations without equipment delays. Proper selection of a filter bag fitted to your facility’s needs can help increase the efficiency of the dust collection system and its operational life. Removal of filter bags for cleaning on a regular basis also increases the working efficiency of the bags.
