MAIN DIMENSIONS

In case of special materials (PE, PVDF, electrically
conductive materials) casings of sizes 100 … 250 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.

Housing position

090R

1) Flanges (round) and frames (rectangular) are made according to MIETZSCH standard MWS 53030.

Drilling pattern:

0 undrilled (such as FO, KOFO)
1 drilled according to series 1 for normal applications (such as KOF1)
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 +
