Table 2: Details of fan series MLF / MLT 75 and 110 Ex (illustrations 2, 3 and 4)

Joh. Mueller Radialventilatoren series ML-, MLF- and MLT are radial fans with suction on one side.
Gaseous media are sucked in axially to the drive axle, redirected by rotor movement by 90 degrees and
radially expelled.

The fans in series ML-, MLF- and MLT- 75/ - 110 consist of housing, rotor and drive motor. They are
supplied  with  direct  drive  as  standard  (design  D)  with  the  rotor  directly  connected  to  the  drive  motor
shaft.  By  contrast  with  the  ML  series  with  their  assembly  frames  of  sectional  steel  the  MLF  and  MLT
series  are  of  flange  design.  The  housings  of  the  radial  fans  in  the  ML  and  MLF  series  are  made  of
