VAV Box Actuators

These Pneumatic Damper Actuators are designed primarily for use on VAV terminal units in HVAC systems.

All models are furnished with a right-angle mounting bracket which affords ease of mounting to the side of a VAV terminal. The actuator can be rotated in the mounting bracket so that the air connection can be positioned where desired. The shaft is terminated with a slot and clevis pin to allow direct connection to the damper linkage of a VAV terminal.

The all metal body allows use in ceiling plenums to meet local safety codes.
