Motor Mounting Methods
for electric and pneumatic actuators

FOR RETROFIT APPLICATIONS, ACTUATORS MUST BE RELOCATED
TO MATCH DAMPER DRIVE BLADE POSITION.

ELECTRIC ACTUATOR
DIRECT-COUPLED,
(EXTERNAL) MOUNTING

If damper is In Duct Install Type, the motor is attached to the duct using the anti-rotation bracket supplied with the actuator. If the damper is Flanged to Duct Install Type the actuator is mounted to the damper's 4" frame using a TAMCO Motor Mounting Bracket. (Part # AL-0001).

ELECTRIC ACTUATOR
JACK SHAFT,
(EXTERNAL) MOUNTING

Motor is mounted on a mounting bracket.
Jack shaft measures 1" (25.4 mm) in diameter.

ELECTRIC ACTUATOR
FACE MOUNTING
(INTERNAL)

Motor is mounted in the airstream. Damper must be ordered with a TAMCO Face Blade Bracket. Required accessories: Belimo ZG-100 Universal Mounting Bracket (Part # BE-8104), appropriate Belimo Crank Arm Adaptor Kit and Belimo Push Rod (dependent on actuator selected).

PNEUMATIC ACTUATOR
DIRECT-COUPLED,
(EXTERNAL) MOUNTING

All mounting accessories required for direct-coupled mounting come with Siemens pneumatic actuators.

PNEUMATIC ACTUATOR
JACK SHAFT,
(EXTERNAL) MOUNTING

Required accessory: Pneumatic Actuator Jack Shaft Clevis Arm (Part # PN-0006).

PNEUMATIC ACTUATOR
FACE MOUNTING
(INTERNAL)

Motor is mounted in the airstream. Required accessory: Pneumatic Actuator Face Mounting Kit (Part # PN-0007).

  • Pneumatic motors must be installed and aligned so as to ensure proper rotation of clamp or crank arm. This requires the actuator to be installed at an angle to match blade rotation. Damper drive rod must not be subjected to pressure that may bow or bend rod out of line.
  • Each pneumatic actuator requires accessories which are specific to its type, model, or brand. The accessories are necessary to mount the pneumatic actuator to the TAMCO damper hexagonal drive rod, or to the TAMCO 1" (25.4 mm) diameter jack shaft. Verify with the actuator manufacturer for a list of appropriate accessories.
  • TAMCO supplies three sizes of Siemens pneumatic actuators (No. 3, No. 4 and No. 6). Models can be purchased with or without positioners. Required accessories are indicated beneath each pneumatic actuator mounting type image. (Refer to Pneumatic Actuator Mounting Accessories page for more details.)
