Aokai manufactures baghouse filter media, filter bags and filter cages.

Service Objectives

Filter bag change-out is the specific process of replacing used filter bags in a baghouse dust collector system. In general, there are two reasons for a Filter Bag Change-out in a dust collector. First, the filter fabric has been compromised by a hole or tear in the fabric which now allows dust to escape. Second, the filter fabric has become fully entrained or clogged with dust particles, which permanently restrict airflow through the filter bags.

The primary objectives of baghouse filter bag change-out are:

  • Maintain Dust Collection Efficiency: As filter bags become clogged with dust, their ability to capture particles decreases. Regular change-out ensures optimal dust collection efficiency, preventing fugitive dust emissions and protecting air quality.
  • Prevent Baghouse Damage: Clogged filter bags increase pressure drop within the baghouse, putting strain on the cleaning system and other components. Timely change-out minimizes pressure drop and protects the baghouse from potential damage.
  • Optimize Energy Consumption: Increased pressure drop also raises the energy needed to operate the baghouse fan. Changing filter bags before they become heavily clogged reduces energy consumption and lowers operating costs.
  • Ensure Regulatory Compliance: Baghouses often fall under environmental regulations for dust emissions control. Regular filter bag change-out helps facilities comply with these regulations and avoid potential fines.
  • Protect Worker Health and Safety: Exposure to dust can be harmful to workers’ health. Changing filter bags before significant dust leakage occurs keeps workplaces safe and protects employee well-being.

Service Description

The frequency of baghouse filter bag change-out depends on several factors, including:

  • Dust Loading: The amount of dust the baghouse handles. Heavier dust loads require more frequent change-out.
  • Filter Bag Material:Different materials have varying dust holding capacities and cleaning efficiencies.
  • Cleaning System Type and Effectiveness:More efficient cleaning systems can extend filter bag life.
  • Operational Requirements:Some applications demand near-zero dust emissions, necessitating more frequent change-out.

Monitoring differential pressure readings and visually inspecting filter bags can help determine the optimal timing for change-out. By following a regular and proper baghouse filter bag change-out schedule, you can ensure optimal dust collection performance, protect equipment, and maintain a safe and compliant operation.

As a general rule, it is better to change out all the filter bags in a collector than a few at a time. Airflow always follows the path of the least resistance, and new filter bags can quickly wear out while they are doing all the heavy-lifting filtration work in a baghouse.
