Inlet/Outlet Flex Connectors (Round and Rectangular)
Flex connectors reduce vibration transmission to/from connecting ductwork and allow for some
misalignment in the installation. Flex connectors are required on all isolated fans and can be
provided by TCF or the customer. Flex connectors are shipped loose for field mounting.

Inlet Silencer (with Support Leg)
Constructed of welded steel with acoustical absorption material to reduce noise emanating from fan
inlet. Flanged connection is suggested for mounting to the inlet of the fan. The opposite end of the
silencer can be furnished with an inlet venturi, inlet flange, or inlet pipe assembly. Unless otherwise

specified, the silencer will be furnished with flanges (punched) at both ends.

Inlet Vanes – External Inlet Vane
Radial vanes at the fan inlet pre-spin the air entering the fan to control the flow. Vanes come
standards with a manual handle operator, but can be provided with an actuator. External vanes have
a housing and are bolted to the fan inlet.

Inlet Vanes – Nested Inlet Vane
Same function as the external inlet vane, but the vanes are nested within the inlet funnel. Replacing
the vanes require the inlet funnel assembly to be replaced.

Motor Positioners
Used for horizontal adjustment of the motor position in one direction.
