Bag Filtration Sizing & Application Guide
HOW TO SELECT A FILTER BAG ?
Our bag filtration systems are widely used for the reduction of sediment from industrial and food applications due to their high flow rate capability, easy maintenance, and rugged design. Siga Filtration can offer filter bags for general particulate removal and high-efficiency removal of particulates. For high flow rate applications, Siga Filtration can offer multi-bag filter housings that can handle flow rates of up to 400 m3/h. All standard filter bags are supplied with integrated handles for easy removal from filter housings. Filter bags are available with removal ratings from 0.5 – 1800 µm.

acuraBag filter bags in Polypropylene, Polyester, or Nylon meshBREWBag food grade filter bags for food & beverage applications. |
acuraBasket – Stainless steel mesh lined baskets that are reusable and cleanable. |
acuraPleat High flow and high-efficiency large diameter elements for applications that require a higher particulate removal efficiency or a larger surface area for high flow rates/low differential pressure. |
FILTER BAG SELECTION BY APPLICATION
|
|
Removal of coarse & fine particulate, sediment removal, carbon fines, resin fines in all types of industrial applications. Water, chemicals, food & beverage. |
|
|
Prefiltration to protect downstream equipment (valves, heat exchangers, sensors)or to increase the life of fine filters. |
|
|
Straining applications. This can be done with Nylon mesh bags or with reusable Stainless Steel mesh baskets |
|
|
Food & beverage applications. Beer, honey, kombucha, specialty teas and water for food production and other alcoholic/non alcoholic beverages. |
|
|
Filtration of paints to remove paint skin, agglomerates and particulates. |
|
|
Sidestream filtration in the HVAC industry – CHW, LTHW, MTHW circuits. Removal of sediment, rust, and suspended calcium deposits. |
WHICH FILTER BAG MATERIAL TO USE?
|
|
|
Polypropylene or Polyester felt for general reduction of particulates. Available micron ratings 1, 5, 10, 25, 50, 100, 200 |
Nylon mesh for removing particulates of a specific size or straining applications. Available micron ratings 1, 5, 25, 50, 100, 200, 400, 600, 800, 1000, 1200 |
BAG FILTER FLOW RATES
Flow rates depend on many factors like application, particulate concentration, micron rating, and viscosity. A general guide to flow rates is provided below for water with 10 micron felt type filter bag.
Size 1 bags – 20 m3/h
Size 2 bags – 40 m3/h
Size 3 bags – 6 m3/h
Size 4 bags – 12 m3/h
