| <BR> | The maximum volume flow of a filter always refers to the norm pressure
p op = 7bar. When pressure changes the maximum through-flow rate of the filter also changes. The change to the through-flow rate can be easily calculated with the aid of appropriate conversion factors f.

| <BR> | Example
A BOGE pre-filter V50 with a nominal performance of 300 m³ /h at a norm pressure of p op = 7 bar is to be operated at p op = 1 0 b a r.
<BR><BR> |
R7 = 300 m³/h
pop = 10 bar Þ f = 1,38
|
R10 = effective rate at pop=10 bar [m³/h]
R7 = effective rate at pop=7 bar [m³/h]
f = Conversion factor for pop=10 bar
At a pressure of p op = 10 bar the filter has an effective nominal performance of 414 m³ /h . |
