Standard Bag Filters (SB)

Features & Information
  • Standard felt bags are of welded construction, where the bag fabric is fused together to create a strong seal, reducing the possibility of loose, fibrous edges migrating downstream
  • Neck rings have two handle tabs which greatly assist bag removal
  • With no metal components, standard bags can be recycled or disposed of by incineration
Applications & Industries

Felt – Polypropylene Applications

  • Pre-filtration in water treatment
  • Paints
  • Syrup
  • Recycled water filtration
  • Trap filter
  • Bulk chemical transfer

Features & Information

Multi-layer bag filtration: the SPECTRUM Standard Bag Filter offers a layer of pre-filtration before the finer filtration layer, maximizing particle retaining efficiency.

FAQs - Standard Bag

How is the Standard Bag different from the Economic and Premier?

The Standard Bag is an extra-life bag with multi-layer construction, ensuring extended service life. It is available in sizes 1 and 2 and is manufactured using polypropylene media. The multi-layer design of the Standard Bag enhances its dirt holding capacity and filtration efficiency, making it suitable for applications where longevity and efficient particle retention are essential.

What is the difference between sizes 1,2,3 and 4 bags?
  • Size 1 = 7″ x 16″
  • Size 2 = 7″ x 32″
  • Size 3 = 4″ x 8″
  • Size 4 = 4″ x 14″
What are bag filters, and how do they work?

A type of liquid filtration system consisting of a flexibleporous bag-like container made of materials like nylon, polyester, or polypropylene. The bag is designed to capture and retain solid particlescontaminants, and impurities from liquids.

Bag filters work by passing the liquid through the porous surface of the bag, allowing clean liquid to pass through while trapping and holding the solid particles inside the bag. The retained particles build up over time, and when the bag reaches its filtration capacity, it is replaced with a new one.

What are the advantages of using bag filters over other filtration methods?

Some advantages of using bag filters include:


  • High Capacity: bag filters have a large filtration surface area, allowing them to handle substantial flow rates and retain a significant amount of solids.
  • Cost-Effective: they generally have a lower initial cost, making them a cost-effective choice for applications with high flow rates and large volumes.
  • Easy Installation: easy to install and replace, reducing downtime during maintenance.
  • Versatility: available in various sizes and materials, suitable for a wide range of applications and liquids.
  • Broad Particle Size Removal: bag filters can effectively remove particles ranging from coarse to fine depending on the filter media used, providing flexibility.
