Types of dust filter bags in the Philippines

Dust Filter bags in the Philippines are made of various materials to cater to different customers' needs. Here are some of them.

• HEPA filter bags

  HEPA dust filter bags are composed of synthetic fiber. The bags capture and remove as tiny as 0.3 microns with 99.7% efficiency. This means that they can filter pollen, pet dander, mold spores, and dust mites. Further, HEPA filter bags work well for people with allergies. To make the dust bag work for a particular need, one should buy bags with specifications corresponding to the intended application. For instance, industrial-grade HEPA bags should be used in industrial settings to achieve the desired results. For the bags to work as intended, they should be installed and maintained correctly. Manufacturers and suppliers recommend regular replacement and timely filter cleaning.

• Microfiber filter bags

  Microfiber dust filter bags are made of polyester material. Compared to standard paper filter bags, these bags have better filtering capabilities. They capture fine dust particles, including pollen and mold spores. Their improved filtration efficiency makes them popular in both commercial and residential vacuum cleaners. Some models even capture 0.3 microns with 99.7% efficiency, just like HEPA bags. Additionally, microfiber filter bags are more durable than traditional filter bags. They can be washed and reused several times before wear and tear.

• Liquid filter bags

  These bags are specifically designed for wet filtration applications. They are made with unique materials that allow them to capture and filter liquid and solid particles simultaneously. The liquid filter bags are used in industries like food processing, chemicals, and pharmaceuticals. They come in different sizes and shapes depending on the intended use and filtration requirements.

• PET filter bags

  The bags are made of polyester (PET), making them heat resistant. They are commonly used in industrial settings where high temperatures and dust levels are generated, such as cement, steel production, and textiles. The bags can withstand high pressure from dust particles and temperatures. This makes them last longer in demanding environments. They are also ideal for capturing very fine dust particles.

Specifications and maintenance of dust filter bags

Dust filter bags have specific specifications according to their application. The governing parameters include the type of material used, the geometrical structure, and distinct features like ease of maintenance and moisture resistance.

• Material: The material of the filter bag determines the amount of dust it can filter. For example, cloth filter bags use woven fabrics that allow only air to pass through while retaining dust particles. In the case of synthetic filter bags, polyester, polypropylene, or PTFE are used to make them more rigid and heat resistant.
• Structural Design: Most dust filter bags have a top closure system. The elastic closure system is used so that the filter bag can fit the baghouse's entry point well. The filter bag often has an open bottom that can get housed in a frame or tube.
• Dust Filtration Efficiency: Dust filter bags are rated according to DFE (dust filtration efficiency). This factor shows what percentage of fine dust particles the filter bag can capture, using a specific particle size distribution.
• Dust Load Capacity: Another governing parameter is the dust load capacity of the filter bag, which represents the amount of dust it can hold before it needs to be cleaned or replaced. Typically, this is represented in grams per square meter (g/m²).
• Moisture Resistance: Moisture filter resistance refers to the ability of the dust filter bag to withstand humid conditions without losing its filtering efficiency. Moisture can damage some materials or reduce filtration efficiency.

Dust filter bags need maintenance to provide optimal services and a longer lifespan. The maintenance requirements for filter bags mostly depend on the type and model of the filter bag. However, generally, the dust filter bags are often cleaned using one of two methods: manual cleaning or automatic cleaning.

• Manual Cleaning: in some cases, the dust filter bags may get uninstalled and cleaned manually. The outer surface of the dust filter bag is washed using a high-pressure jet cleaner or air compressor to blow out the clogged dust.
• Automated Cleaning: modern filter bags are equipped with an automated cleaning mechanism. Usually, they have a pulsing system that pulses compressed air at regular intervals. The pulsed blasts blows the dust out of the filtering fabric, thus cleaning it.

Uses of dust filter bags

Dust filter bags are quite versatile owing to their varied uses. Here are several applications and industries where the use of dust bags is common:

• Cleaning products

  Dust filter bags are used in vacuum cleaner manufacturing. They serve as the core filtration component of the device where the captured dust and debris awaits. In the case of bagless dust filters, this idea applies more as they will have a filter bag as a virtual backup.

• Industrial dust extraction systems

  In heavy manufacturing industries in the Philippines that produce large volumes of dust-weighing mortars such as construction, a-dust filter bag is essential to keep the air within the premises clean and breathable. Production factories install baghouses fitted with dust filter bags as part of the ventilation system so that workers operating within the factory can live in a comfortable setting. The same motivation applies to the use of dust filter bags in mining and metallurgy industries that deal with fine metallic dust, as well as food processing factories that mill grain.

• Dust collector filter bags

  Dust collector filter bags also referred to as a dust filter bag, serve the exact same purpose as industrial dust filters, which is to trap the fine pulverized dust from the air within the premises. A baghouse is the design most commonly associated with dust collector filter manufacturers. It comprises a large number of vertical filter bags. Once the dust filters bags are full, the collected debris is usually blown out by reverse air flow, and the dust filter bags are collected for further processing.

• Dyeing industry

  Preserving the natural environment is crucial. The dyeing industry is one of the significant polluters. Dust filter bags play an essential part in detaining the production of dust and keeping it from contaminating the surroundings.

• Spray drying filters

  Spray drying filters are installed at the end of the spray dryer to separate the dried powder from the humid air. Dust filter bags play a part in delivering a safe and sound work environment and emitting minimal dust into the surroundings.

How to choose dust filter bags

Several factors should be considered when selecting industrial filter bags for dust. Buying custom filter bags that fit the specific application of an industrial machine can make the air more breathable. Some of these factors include:

• Dust filter bag materials: Dust filter bags may be made out of either natural or synthetic fibers. Each option has its own set of benefits. While synthetic fibers provide more strength and resilience, natural fibers have superior filtration ability. Examine the needs of the air filtration system in order to pick the material that works best for it.
• Dust collector filter bag design: Dust filter bags come in a variety of designs. The choice of which design to use should be based upon factors such as the model of the air filtration system and the kinds of materials being filtered. Opting for a bag that blends well with the dust collector optimizes filtration performance.
• Cleanability: Consider the dust filter bag's ability to be cleaned and reused. Some bags can be mechanically cleaned, while others require manual cleaning or replacement. Evaluate the bag's cleanability and maintenance requirements to determine its long-term cost-effectiveness, given the potentially high-frequency use of dust filter bags in industrial settings.
• Industry standards and certifications: When selecting a dust filter bag for use in industrial settings, it's important to consider certifications and compliance with industry standards. Opt for bags that meet recognized standards to ensure quality, safety, and environmental compliance. Using filter bags that adhere to established regulations minimizes the risk of legal and operational issues.
