Pulse bag dust collector vs filter cartridge dust collector: a guide for factory selection of high-efficiency dust removal equipment
Aug 30,2025
The core of selecting dust removal equipment for factories is "adaptation to working conditions" - although pulse bag dust collectors and filter cartridge dust collectors belong to high-efficiency dust removal equipment, there are significant differences in filtration accuracy, processing capacity, and applicable scenarios. Only by combining the characteristics of dust, production scale, and green environmental protection needs can we select equipment that is "not wasteful and easy to use", especially suitable for the compliance and operation and maintenance needs of overseas factories.
1、 Core difference: Three dimensions to identify the "areas of expertise" of the two devices,
filtration accuracy
Pulse bag filter is suitable for medium and coarse dust particles larger than 0.5 μ m, with a removal rate of up to 99.5%+;
The filter cartridge dust collector is good at handling fine dust particles of 0.1-0.3 μ m, with a removal rate of up to 99.9%+.
Handling air volume
The single unit air volume of the pulse bag filter is between 10000 and 100000 m ³/h, suitable for high air volume factories such as cement plants;
The single unit air volume of the filter cartridge dust collector is 5-30000 m ³/h, suitable for small and medium air volume workshops, such as electronic factories.
Temperature and corrosion resistance
The filter bag of the pulse bag dust collector can be made of PPS material or PTFE material, which can adapt to high temperature and corrosive working conditions;
The filter cartridges of dust collectors are mostly made of polyester film, which is more suitable for scenarios at room temperature and without strong corrosion.
maintenance cost
The lifespan of the pulse bag filter bag is 1-2 years, and the replacement cost is moderate, making it suitable for continuous production factories;
The filter cartridge of the dust collector has a lifespan of 2-3 years, making it easy to replace and maintain in small and medium-sized factories.
2、 Factory selection: more efficient based on "scene matching"
1. Choose three types of factories for pulse bag dust collectors
High air volume+medium coarse dust factory: such as cement plant grinding workshop, mining crushing section, a single machine can cover an air volume of 100000 m ³/h, without the need for multiple equipment splicing, reducing system complexity;
High temperature/corrosion condition factories: such as Middle Eastern chemical workshops and Nordic pharmaceutical factories, choose temperature/corrosion resistant filter bags that comply with EU REACH material requirements;
Pursuing long-term energy-saving factory: The equipment resistance is 15% lower than traditional cloth bags, coupled with variable frequency fans, saving over 8000 kWh of electricity annually, in line with the trend of "green environmental protection", and helping the factory achieve ESG reporting standards.
2. Choose three types of factories for filter cartridge dust collectors
Fine dust+small and medium air volume factories: such as electronic factory welding fumes, metal fine powder in hardware factories, with a 0.3 μ m dust removal rate of 99.9%, meeting the ultra-low emissions requirements of the US EPA ≤ 5mg/m ³;
Workshop with limited space: The equipment volume is only one-third of that of a bag filter with the same air volume, suitable for small precision factories in Europe and America;
Factories that are afraid of trouble in high-frequency replacement: The filter cartridge can be replaced individually without the need to shut down and disassemble the whole, reducing maintenance time by 60% and adapting to factories with high labor costs in Southeast Asia.
3、 Foreign trade adaptation: compliance+green environmental protection dual guarantee
Both devices comply with mainstream global environmental standards, but require targeted adjustments:
EU market: CE certification is required, filter cartridge dust collectors are preferred for fine dust scenarios, and heat-resistant cloth bags are selected for high temperature scenarios;
North American market: Compliant with EPA standards, equipped with anti-static design, capable of handling flammable and explosive dust;
Emerging markets: Providing SGS testing reports, the "high cost-effectiveness+durability" of bag filters is more suitable for African mines, and the "easy maintenance" of filter cartridges is favored by small and medium-sized factories in Southeast Asia.
In addition, both devices support dust recovery with a recovery rate of over 90%, reducing the cost of solid waste disposal and perfectly aligning with the concept of "green environmental protection" - helping factories reduce costs while also conforming to the global low-carbon trend.
4、 Selection Summary: 3 Steps to Quickly Determine Equipment
1. Look at dust: For fine powder (≤ 0.5 μ m), choose a filter cartridge, and for medium coarse powder (≥ 0.5 μ m), choose a cloth bag;
2. Check the air volume: If the air volume in a single room is greater than 30000 m ³/h, choose a cloth bag, and if it is less than 30000 m ³/h, choose a filter cartridge;
3. Depending on the working conditions: choose a cloth bag for high temperature/corrosion, and a filter cartridge for room temperature/small space.
Choosing the right pulse bag or filter cartridge dust collector is not just about choosing "efficient dust removal equipment", but also about choosing a green solution that "meets the needs of the factory and complies with overseas regulations", helping you find the optimal balance between production and environmental protection.
