Ambient pressure range:
700 to 1100 mbar, corresponding to
~4200 meters (13800 feet) above sea
level to ~700 meters(2300 feet) below
sea level, at normal atmospheric
pressure.
As seen in the graph above, the ventila-
tor is unable to deliver set max pressure
at a very low ambient pressure.
Ingress Protection:
IP22
Solid particle protection: Hazardous parts are protected from touch by fingers and by
objects greater than 12 mm.
Liquid ingress protection: The protection withstands dripping water less than 15 degrees
from vertical.
The ingress protection has been tested by water drips equivalent to 3mm rain/minute
for 10 minutes (2.5 minutes for each tilting direction).
