Dust Collector Filter Bags

Dust Collector Filter Bags

Filmedia® – Industrial Filter Bag Manufacturer

Filmedia® provides a wide range of high quality filter bags for industrial Dust Collector. Filmedia® dust collector bags series are high dirt capacity filter bags, optional double-layer structure, effectively increase the filtration area and dirt holding capacity, at the same time, double-layer dirt interception, interception efficiency is more significant. Our Extended Life filter bag provides superior filtration of all sized particles.

  • Dust collector bags are made of needled felt. According to the adjustment of the thickness and thickness of the needled felt, the filter bag can achieve higher accuracy, removal rating is usually higher than 90%.
  • The surface of the filter bag is treated with singeing, matte process and coating, avoid fiber shedding.
  • The hot melt seamless combination technology is adopted to ensure that the filter bag will not have side leakage phenomenon.

Filtration Principle in Woven and Non-woven Fabric

Filtration Principle in Woven and Non-woven Fabric

In a woven fabric, the particle gets collected by one or more of the mechanisms (like interception, internal impaction etc.) resulting in a buildup of dust cake’ which is mostly on the surface.

Filtration Principle in non-woven fabric

In a non-woven fabric, the waste not only on the surface resulting in a build up of dust cake’ but also in-depth.

  • Installation
    According to the structure and design of the equipment, install the filter bag to the filter bag frame or filter bag room of the dust removal equipment. Make sure the filter bag is installed securely with no looseness or gaps.
  • Check Before Operation
    Before starting the dust removal equipment, check whether the filter bag is intact and not damaged or broken. Make sure the filter bags are clean and in good condition for optimum filtration.
  • Activating the Equipment
    Activating the dust extraction equipment allows air to flow through the filter bags. Dust and solid particles will be captured by the filter bag, while clean air will be exhausted through the filter bag.
  • Periodic Inspection and Maintenance
    Periodically check the condition of the filter bags and clean or replace them as needed. When the dust accumulated on its surface will affect the filtration efficiency, it needs regular maintenance.
  • Cleaning
    When a large amount of dust has accumulated on the surface of the filter bag, which affects the air circulation and filtration efficiency, it needs to be cleaned. The cleaning method can be mechanical vibration, pulse back blowing, etc., to strip the dust from the surface of the filter bag.
  • Replacing
    Filter bags become worn or damaged over time and need to be replaced. When replacing, make sure to select the appropriate model and specification, and operate according to the operation manual of the equipment.
  • Pay attention to safety
    When cleaning, replacing or maintaining filter bags, be sure to follow the equipment operating procedures and safety operation guidelines to ensure the safety of operators.
  • Record maintenance
    Establish filter bag maintenance records to record the cleaning, replacement and maintenance of filter bags for effective management and planning.
