Which filter bag material to use?  

Considerations to make when choosing the best filter bag material.

Polypropylene felt is the ideal bag filter material. Nylon mesh can be a suitable bag filter 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 see the information below comparing filter size against flow rate.

Filter size

Flow rate

PBH Size 10 Housing 50 lpm (3 m3/h)
PBH Size 20 Housing 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)
