Bearing Dowel Pins
Bearing dowel pins hold the position of the bearing to confirm proper alignment. A rod is fixed to the
pedestal for mounting through a hole on the bearings.

Bearing Vibration Sensor
Sensors are used for monitoring vibration levels at the fan bearings. The bearing housing is drilled
and tapped. Sensors are typically shipped loose for field mounting as damage could occur in transit.
Other mounting methods could include a bracket mounted through the bearing bolt or epoxy
mounting to the housing.

Blast Gate
A wafer-type butterfly valve for mounting to outlet flange allows controlling flow to full shutoff.
Available for automatic control. Maximum temperature 250°F. The Blast Gate & flange bolt pattern
match 125# ASA Pipe Flange.

Clamshell Fans – Axial Fans (Single & Double Door)
Clamshell fans are available designed to provide complete access to the interior of the fan for
maintenance or cleaning without removal of ductwork. Clamshell construction is available for inline
centrifugal and axial fans and is typically used in vertical mount applications. For the double door
configuration, one of the two access doors is wide enough for wheel removal.
