Pressure Drop vs. Flow Rate
Data for pressure drop versus flow rate is provided based on 1 ft² (0.09 m²) of filtration media. The differential pressure should be divided by the media square footage of the selected bag.
Pressure Drop (Psi/ft² of surface media) / (bar/ft²)
- 0 / -
- 0.2 / 0.01
- 0.4 / 0.03
- 0.6 / 0.04
- 0.8 / 0.06
Flow Rate (GPM of water, 1 cps @ 77°F) / (Lpm, 1 cps @ 25°C)
