Frequently Asked Questions (FAQ)

Q1: What is the typical lifespan of your damper actuators?

Our actuators are built for reliability, lasting over 80,000 cycles under normal conditions. Actual lifespan depends on installation environment and usage frequency.

Q2: What types of damper actuators do you supply?

We manufacture ON/OFF, modulating, spring-return, and non-spring-return actuators. Selection depends on your HVAC design and damper requirements.

Q3: How does a damper actuator work?

It is an electromechanical device that controls the opening and closing of HVAC dampers, receiving signals from thermostats or automation systems to regulate airflow.

Q4: Are your actuators certified?

Yes, our products are CE, RoHS, and ISO certified, ensuring compliance with international safety and performance standards.

Q5: How easy is installation and maintenance?

Installation is straightforward: the actuator mounts directly onto the damper shaft. Maintenance is minimal and usually requires only periodic inspection.
