MAIN DIMENSIONS
Casings of sizes 315 … 560 consist of two even side walls
and one jacket welded together.
The dimension sketch shows
housing position 090R .
For other positions the manufacturers turn the casing
around the fan axis.
The smooth connection on the suction side has diameter
d = nominal diameter. The smooth connection on the
pressure side is rectangular a x b.
Many connection variants are possible to meet customers'
demands.
Design version ELA, vibration isolators, and a
condensate bore with closing cap are elements of the
standard range of delivery. Other versions have to be
ordered separately.

2 drilled according to series 2 (double number of screws) for high pressures and large quantities of
condensate (such as F2, KOF2)
l and h are functional dimensions applying to the
corresponding casing connection.
In the case of KOF, for instance, the distance fan
axis/flange amounts to c + I2 or g5 +
h6 .
