Comparison of Selection between Plastic Burn Plate and Filter Cartridge Dust Collector
Mar 09,2026
In the field of industrial dust control, both plastic fired plate dust collectors and filter cartridge dust collectors are high-efficiency dry filtration equipment widely used in various industrial scenarios. Although the core functions of the two are the same, there are significant differences in filtering mechanisms, performance characteristics, applicable scenarios, and operation and maintenance costs. Reasonable selection is the key to ensuring dust removal effectiveness and controlling operating costs.
1、 Core filtration mechanism and structural differences
The plastic fired board dust collector uses plastic fired board as the filtering element and adopts surface filtration mechanism. The filter material is a porous rigid structure, and the dust only adheres to the surface and does not penetrate the inside of the filter material. During dust cleaning, the dust can be completely peeled off without residual hazards, and there is no need for skeleton support, making the structure more stable. The filter cartridge dust collector adopts a foldable filter cartridge as the filtering element, which also focuses on surface filtration. The filter material is mostly flexible materials such as polyester fiber and PTFE film, which need to be fixed with a skeleton. Dust is prone to remain in the folds and gaps, making dust cleaning difficult. Long term operation may cause deformation of the filter material.
2、 Comparison of key performance parameters
1. Filtration efficiency: Both can achieve efficient filtration (over 99.9%), but the plastic fired board has a smooth surface and no wrinkles, making it more stable in intercepting fine dust (PM2.5) and viscous dust, and less prone to efficiency decline due to dust blockage; The filter cartridge dust collector is affected by the wrinkled structure, and viscous dust is prone to adhere and accumulate, resulting in a slight decrease in long-term operating efficiency.
2. Dust removal effect: The plastic fired board uses high-pressure pulse blowing for dust removal, which thoroughly peels off the dust, has a low dust removal frequency, and consumes less air; The filter cartridge requires high-frequency spraying to clean the dust inside the folds, which not only consumes a large amount of air, but also may damage the flexible filter material due to high spraying pressure, shortening its service life.
3. Resistance characteristics: The rigid structure of the plastic fired board is not easily deformed, the operating resistance is stable (usually between 800-1200Pa), and it is less affected by fluctuations in dust concentration; The filter cartridge is prone to increased resistance due to dust accumulation and deformation of the filter material, and requires frequent maintenance to maintain stable operation.
3、 Differences in applicable scenarios
Plastic fired plate dust collectors are more suitable for harsh working conditions, such as high concentration, high humidity, viscous dust in mining, metallurgy, chemical and other industries, or scenes containing acidic and alkaline corrosive gases. Their rigid filter materials are wear-resistant, corrosion-resistant, and anti condensation, and their service life can reach 3-5 years. In addition, scenes with limited space are also more suitable, as they have a larger filtering area per unit area and a more compact device volume.
The filter cartridge dust collector is more suitable for scenarios with high cleanliness requirements and dry and non sticky dust, such as dust control in industries such as mechanical processing, woodworking, and electronics. It has high filtration accuracy, low initial equipment investment, and easy installation, making it suitable for small and medium-sized enterprises or temporary dust removal needs. But it is not suitable for high humidity and high viscosity dust scenes, otherwise it is prone to filter cartridge blockage and failure problems.
4、 Comparison of operation and maintenance costs and service life
Service life: Plastic fired plate filter material has strong rigidity and wear resistance, with a service life of 3-5 years under normal maintenance; The filter cartridge is made of flexible material, which is prone to wear and deformation. Its service life is usually 1-2 years and requires frequent replacement.
Operation and maintenance costs: The initial investment in plastic fired boards is slightly higher, but the frequency of dust cleaning is low, the gas consumption is low, the replacement cycle is long, and the long-term operation and maintenance costs are lower; The initial investment of the filter cartridge is low, but it requires frequent replacement of filter materials and consumes more compressed air, resulting in higher long-term operation and maintenance costs. In addition, the plastic fired board does not require replacement of the skeleton, reducing accessory wear, while the replacement of the filter cartridge requires synchronous inspection and replacement of the skeleton, increasing maintenance workload.
5、 Selection core suggestions
The core of selection lies in matching the working conditions and cost expectations: if the working conditions have high dust concentration, high viscosity, high humidity, or contain corrosive gases, and pursue long-term stable operation and reduce operation and maintenance costs, plastic fired plate dust collectors are preferred; If the working conditions require dry and non sticky dust, high cleanliness, limited initial budget, and short-term use, a filter cartridge dust collector can be chosen.
In addition, foreign trade practitioners need to pay attention to the differences in operating conditions in different regions (such as tropical high humidity areas and cold regions with low temperatures), which can affect equipment selection. It is necessary to recommend suitable equipment types based on the characteristics of local industrial scenarios, while paying attention to the temperature and corrosion resistance of filter materials to ensure that the equipment is suitable for the local usage environment.
