Which filter bag material to use?

Considerations to make when choosing the best filter bag material.
Polypropylene 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 50, 100, 200, 400, 600

Typical Water Flow Rates

Please the information below comparing filter size against flow rate.

Filter Size
PBH Size 10 Housing
PBH Size 20 Housing
Flow Rate
50 lpm (3 m3/h)
100 lpm (6 m3/h)

* With 25 micron PP felt bags
* * Please note that flow rates may vary depending on application – i.e. dirt load, viscosity, micron rating etc.

What is the Micron Rating of various particles?

A micron is a unit of measure and equals one thousandth of a millimetre.

  • 1mm = 1000 microns (micrometer)
  • 1 inch = 24,500 microns (imcrometer)
