Type code of the Automatic Purging Units Series F-BO-AFE70
The Automatic Purging Units F-BO-AFE70-2 and F-BO-AFE70-3 have outer dimensions and func-
tionality in common, they essentially differ in the built-in solenoid valves which allow different air
flow rates and/or extended operating temperatures. The Automatic Purging Unit F-BO-AFE70-2
with a typical air flow rate of the solenoid valve of approx. 3,500 l/min (ANR) at 0.7MPa (7bar) is
designed both for small as well as for larger pipe systems with a large number of aspiration holes.
Thanks to the solenoid valve's typical air flow rate of approx. 5,000 l/min (ANR) at 0.7MPa (7bar),
the Automatic Purging Unit F-BO-AFE70-3 is suitable for even larger and further-flung pipe sys-
tems, and in addition it allows use in environments with low temperatures (down to -20°C). Notes
with regard to dimensioning can be found from page 14 onwards in Chapter 4: „Pneumatic com-
ponents – dimensioning". The functions of the Purging units are described starting on page 10 in
Chapter 2: „Manner of operation of a Purging unit".
The information in this User Manual relates to the firmware release number PL0200_V_1.00 of the
control board. In Fig. 11 the position of the label is indicated where the version of the firmware
used can be read. Devices using firmware with another release number can differ in their function
from the range of functions described in this document.
1.2
