Operation limits of the Automatic Purging Unit F-BO-AFE70-2, depending on the input pres-
sure that is available during the Purging process („input overpressure“) and the sum of the aper-
ture areas of the piping that is to be connected to the Purging unit („total aperture area“). The
Automatic Purging Unit F-BO-AFE70-2 must not be operated with input overpressures of more
than 0.7MPa (7bar)!

Table 5:
Operation limits of the Automatic Purging Unit F-BO-AFE70-3, depending on the input pres-
sure that is available during the Purging process („input overpressure“) and the sum of the aper-
ture areas of the piping that is to be connected to the Purging unit („total aperture area“). The
Automatic Purging Unit F-BO-AFE70-3 must not be operated with input overpressures of more
than 1.0MPa (10bar)!
The Automatic Purging Unit F-BO-AFE70 still works perfectly at and below an input overpres-
sure of 0.1MPa (1bar), but perhaps the resulting pressure built up in the pipe network will not
suffice to open the check valve and to clean the pipe network completely.
If the sum of the area of the aspiration holes of the piping exceeds the specified values, branches
can also be purged, by means of the master-slave mode (see from page 34 onwards in Chapter
9.4.2: „Connection of Purging units in the master-slave mode with direct actuation through the
fire detection control panel (in accordance with EN 54-13)“), through separate Automatic Pur-
ging Units F-BO-AFE70. This also applies analogously to the areas marked with „-“ in the
Tables 4 and 5.
4.2
Compressed-air supply
The required size of the air vessel as well as the air delivery volume of the compressed-air supply
essentially depend on the following factors:
positive operating pressure of the compressed-air supply (air vessel overpressure)
chosen input overpressure of the Purging unit
total opening time of the solenoid valve during the Purging process.
