FAQs - Economic Bag

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

The Economic Bag filter is a single-layer bag designed to provide a cost-effective filtration solution. It is available in sizes 1, 2, 3, and 4, and offers slightly reduced dirt holding capacity compared to the Standard and Premier bags. The Economic Bag provides versatility with multiple media options, such as polypropylene, polyester, and nylon, catering to various filtration needs.

For the same explanation of Standard and Premier Bags please visit their respective pages.

What is the difference between size 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.
