"ACTUATOR
Honeywell High Force Damper Actuator for Industrial Fans and Blowers.
Honeywell's dual-side HVAC actuator can be used to open or close a duct damper for most 2-, 3-, 4-, and 6-speed volume controls. The spring return softens the air flow when the actuator is finished moving. This model is compatible with low pressure, high temperature applications and comes with an adapter for mounting.
The Honeywell MP918B1030 is a High Force Damper Actuator with Spring Return for Variable Volume Units (3 to 13 psi).
High Force Spring return damper actuator can be used to regulate airflow for air volume systems from 3-13 psi. This valve is recommended for use with wood pellet fuel."
The Honeywell Damper Actuator (L92DH/J) is designed for use with XQ50, XQ60, and XQ100 Air Cleaners. It is a high force, spring return actuator that will vary the speed through the damper by positioning the lever to match the desired fan speed setting.
The Honeywell MP918B1030 High Force Damper Actuator with Spring Return for Variable Volume Units (3 to 13 psi) is simple to install and includes a new damper spring return lever. Delivers consistent flow-rate performance.
The Honeywell High-Force Actuator opens your damper doors to a full 6-in. stroke, so you can achieve the airflow you need for optimum comfort and energy efficiency. It features a molded plastic housing with a metal lever arm and metal spring return.
