MP918A and B Pneumatic

Damper Actuators

77-3080-1

SPECIFICATION DATA

GENERAL

The MP918A and B Damper Actuators position damper

blades, controlling the airflow through a particular portion of

an HVAC system. The MP918A is the same as the MP918B

with a positive positioner.

FEATURES

• Rolling Diaphragm operated

• Low friction shaft bearing

• Close tolerance on operating range and stroke

• Versatile mounting and connecting hardware

• Models available for use with UL classified leakage

rated (smoke) dampers

• Cost efficient mounting to Honeywell dampers

• Nonoverlapping spring ranges for sequencing

• Reliable—long life
