Why do your dust collector filters clog easily? First, understand the difference between materials and principles!

Under normal circumstances, dust collector filters rely on the surface filtration mechanism of PTFE membrane filter media. 

Dust only adheres to the surface of the filter media and does not penetrate. The surface is smooth and easy to clean, so clogging should not be a problem. 

If clogging occurs, the core reasons are usually improper operating conditions, incorrect filter media selection, or improper use and maintenance. 

Specifically, these can be divided into the following categories:

1. Operating conditions exceeding the suitable range: 

The concentration/humidity of the dust-laden gas being processed exceeds the standard, the dust has extremely strong adhesion, or condensation occurs causing dust to clump and adhere, making conventional cleaning ineffective.

2. Improper filter media selection: 

Failure to select the correct filter media according to the dust characteristics (particle size, corrosiveness, humidity, etc.) leads to damage to the filter membrane, loss of surface filtration advantages, and dust penetration into the interior, forming deep clogging.

3. Improper Use and Maintenance:

① Excessive filtration flow (accelerates dust adhesion, causing a surge in resistance)

② Untimely dust removal/poor effect (dust accumulation exceeds capacity)

③ Seal failure (short circuit of dust-laden gas, localized blockage) 

Differences in Filter Material and Principle of Dust Collector Filter Cartridges:

1. Rigid filter media folded into a cylinder, compact structure, sufficient filter element spacing, thorough dust removal, no secondary pollution.

2. Filter bags use soft filter media sewn together, with an electromagnetic pulse valve sleeve and a welded steel frame. The filter bags are vertically densely packed, the filter media is long polyester fiber, and the base material is mostly a single layer of ordinary industrial polyester cloth.

3. Dust collector filter cartridges use a surface filtration mechanism, where dust only adheres to the surface of the filter media and does not penetrate into the interior; baghouse dust collectors, on the other hand, use a deep filtration mode, 

where dust penetrates into the interior of the filter media, relying on a dust layer formed on the outer surface of the filter media to ensure dust removal efficiency. 

Dust collector filter cartridges have completely revolutionized traditional dust collectors, overcoming their limitations in meeting high-demand requirements. 

Cartridge dust collectors eliminate filter media wear issues, have no moving parts, and can operate stably for extended periods without frequent maintenance. 

This completely eliminates the need for repeated filter media replacements required by traditional dust collectors, offering multiple advantages such as cost-effectiveness, time-saving, labor-saving, and no secondary pollution.

Dust collector filter cartridges use specially molded filter media as their core, combined with a support frame, sealing end caps, and rubber sealing rings. 

The components are integrated and bonded using high-strength special adhesive. As the core carrier of filtration efficiency, 

the selection of filter paper must be precisely matched to the application scenario and media characteristics (such as dust particle size, humidity, and corrosiveness). 

This directly determines the filtration capacity and service life of the cartridge. More importantly, there is no fixed standard for cartridge lifespan; 

differences in operating conditions and media variations will affect its service life. For the same specification product, exceeding the flow rate limit will cause a surge in initial resistance and a sharp reduction in lifespan. 

Conversely, proper flow control can significantly extend its effective service life, achieving an optimal balance between filtration efficiency and operating costs.
