Industrial dust removal framework: adapted to filter bags to extend service life
Sep 26,2025
In industrial dust removal systems, filter bags are frequently damaged and have a short lifespan. They are often wrinkled and worn due to poor fitting of the dust removal framework and mismatched sizes, resulting in rough structures that break the filter material. The annual cost of replacing bags exceeds 10000 yuan. Customized industrial dust removal skeletons can reduce filter bag loss from the root and become an "invisible helper" for overseas factories to reduce costs.
1、 Three major adaptive designs, the protective filter bag is more durable
1. Accurate size, no "mismatched" wear and tear
Customize the skeleton according to the size of the filter bag: diameter error ≤ 2mm, length matching the height of the filter bag to avoid excessive bursting or insufficient sagging and dust accumulation. The gap is controlled at 3-5mm to ensure that the filter bag is fully unfolded and there is no local squeezing wear during dust cleaning. The service life of the filter bag is extended by more than 30%.
2. The structure is wear-resistant and free from potential scratches
Adopting CNC welding+full polishing process: the welding points are flat and free of welding slag, the corners are treated with R3mm rounded corners, the surface roughness is ≤ Ra1.6, there is no hooking during bagging, and there is no friction during dust cleaning vibration, completely avoiding the problem of traditional skeleton "burrs scratching the filter bag".
3. Material adaptation, resistant to "working condition" damage
Choose skeleton material according to working conditions: galvanized carbon steel is used for ambient temperature drying scenarios; 316L stainless steel is used in chemical corrosion scenarios; Aluminum plated carbon steel is used for high temperature conditions to avoid skeleton corrosion/deformation and squeeze filter bags, which is suitable for multiple industrial scenarios overseas.
2、 Foreign Trade Adaptation: Adapting to Global Needs
1. Compliance certification
The material has passed SGS testing and meets EU REACH and US FDA standards, with no obstacles to exporting food and electronics to factories; ATEX certification can be provided for explosion-proof scenarios, suitable for chemical explosion-proof workshops.
2. Regional customization
High humidity area: The skeleton is passivated and coated with a hydrophobic layer to prevent rust and corrosion;
High temperature zone: Use high-temperature resistant seals to avoid damage to the filter bag caused by thermal expansion and contraction of the skeleton;
Small factory: Provides detachable skeleton for easy installation in narrow spaces.
3、 Actual benefits: cost reduction and worry free
Although the cost of adapting the skeleton is 10% higher than the general model, the filter bag replacement cycle has been extended from 6 months to 12-18 months, saving 50% of the annual filter material procurement cost and reducing downtime and bag replacement losses. For overseas factories, it is a "small investment, big return" choice.
For overseas industrial customers, the adapted dust removal framework is not a "simple support", but a "protective shell of the filter bag" - relying on precise adaptation to extend the service life of the filter bag, reduce operation and maintenance costs, and also meet global working conditions and compliance requirements, allowing the dust removal system to operate stably for a long time.
