A: The service life of filter media has no fixed value and depends on operating conditions, generally ranging from 1 to 3 years. Methods to extend its service life are as follows:

Reasonable ash cleaning: Avoid over-cleaning (which may damage the dust layer) or insufficient cleaning (which may cause clogging).

Pre-coating protective layer: For viscous dust or new filter bags, pre-coating with ash can be applied for protection.
Avoid dew condensation: In cold environments, it is necessary to insulate the dust collector box to prevent water vapor from condensing on the filter media.

Regular professional maintenance: Conduct regular inspection and maintenance with the support of our professional after-sales service team.

A: Insufficient air source pressure: Unable to provide enough blasting force to shake off the dust.

Oil and water contained in compressed air: Oil and water will adhere to the dust, aggravate the filter bag clogging, and may damage the pulse valve.

Failure of the oil-water separator: It is necessary to regularly discharge the accumulated water in the air storage tank and water separator.

Recommendations: Ensuring a supply of dry, clean and pressure-stabilized compressed air is the key to guaranteeing the ash cleaning effect.

A: Filter media clogging: This is the most probable cause. Excessive resistance of the filter media leads to a decrease in air volume.

Duct clogging: Severe dust accumulation occurs inside the ducts, especially at elbows or diameter-changing sections.

System leakage: Air leakage points exist in the ducts or dust collector cabinet, which divert the effective air volume.
Improper opening degree of the fan valve: Check whether the fan inlet regulating valve is in the correct position.

A: "Dust emission" means that dust has penetrated the filtration system, with the main causes as follows:

Filter cartridge/bag damage: This may be caused by airflow scouring, abrasion or corrosion.

Poor installation sealing: The sealing ring between the filter bag opening and the tube sheet is aged or not compressed tightly, resulting in an air bypass.

No pre-coating before initial use: New filter media have relatively large pores, and a dust layer needs to be formed first to achieve the optimal filtration state.

A: Abnormal ash cleaning system: Damaged pulse valves, insufficient compressed air pressure, or excessive moisture in the compressed air.

Filter media clogging: Filter cartridges/bags have reached their service life, or the processed dust is highly humid and viscous, leading to clogging.

Improper ash cleaning program: Excessively long injection intervals result in incomplete ash cleaning.

Excessive dust load: The inlet dust concentration far exceeds the designed value.

Solutions: Check the air source and pulse valves, optimize the ash cleaning program, or replace with specially treated filter media such as oil-water resistant or PTFE membrane-coated types.

A: It depends on the characteristics of the dust. For dry and fine dust, a cartridge dust collector is preferred; for wet and sticky dust, a wet dust collector is a better choice; and for high-temperature and large-airflow conditions, an electrostatic precipitator can be considered. Cartridge dust collectors feature a compact structure but come with a slightly higher filter material cost, while baghouse dust collectors may have a lower initial investment.
