Port section walls are
flush with duct inner walls, minimizing pressure drop.
Port section carries
duct axial and shear loads through side frame members.
Patented shallow seal
air chamber provides outstanding rigidity.
All port section welds
are continuous; structural welds have full penetration.
Internal blade supports
limit the deflection of the blade as it enters the bottom seal.
capable of resisting the upset duct pressure and a one "g"
Flushable trough under
the bottom seal prevents deposit accumulations in the bottom seal
Open superstructure allows
ready access for maintenance and inspection.
Bearing mounts take drive loads
into the frame through safe compessive load paths.
A transverse beam cooperates
with the drive shaft to ensure seismic stability.
Positive safety stops prevent
movement of the blade past the normal operating limits.
