Description
The Honeywell MP918B1105 is a high-force, spring return pneumatic damper actuator engineered for precise and reliable damper control in commercial HVAC and building automation systems. Designed to handle demanding applications, this actuator delivers consistent positioning performance across a wide range of environmental conditions.
Key Features
- High actuator force for demanding damper control applications
- Spring return design ensures fail-safe damper positioning on loss of air pressure
- 3-1/2″ (3.5″) stroke for broad damper compatibility
- 8–13 PSI spring range for precise modulating control
- 29 PSI maximum operating pressure
- 1/4″ barbed fitting for OD plastic tubing connection
- Wide humidity tolerance: 5–95% RH (non-condensing)
- Extended operating temperature range: -40°F to 158°F (-40°C to 70°C)
Application
The MP918B1105 is ideal for use in VAV systems, air handling units, economizer dampers, and other pneumatically controlled HVAC applications where high actuator force and reliable spring return operation are required. The broad temperature and humidity ranges make it suitable for both indoor mechanical rooms and outdoor or semi-conditioned spaces.
