Air Valve Electric Control Damper Actuators
Product Description
Electric Control Damper Actuators for Accurate Airflow & Multi-Scenario HVAC Use
A damper actuator is a key electromechanical part for HVAC systems. It precisely adjusts damper positions to regulate air volume, airflow speed and air distribution. It keeps ventilation efficient and maintains stable indoor temperatures all the time.
Application:
Industrial Ventilation Control
They are used in factories or chemical plants to regulate exhaust dampers, ensuring safe removal of fumes, smoke, or hazardous gases while maintaining airflow balance in ventilation networks.
HVAC Systems for Temperature Regulation
Damper actuators automatically adjust airflow in heating, ventilation, and air conditioning (HVAC) systems to maintain desired room temperatures by modulating duct dampers in response to thermostat signals.
Cleanroom Pressure Control
In laboratories, hospitals, or semiconductor facilities, damper actuators maintain precise pressure differentials between cleanrooms and adjacent areas to prevent contamination through airtight dampers.
Building Automation and Energy Efficiency
Integrated with smart building systems, damper actuators optimize energy use by adjusting outdoor air intake (e.g., demand-controlled ventilation) or closing dampers in unoccupied zones to reduce heating/cooling waste. Customizable fail‑safe power‑off closing function available: we adopt DC geared motor plus super‑capacitor energy‑storage circuit for cost‑sensitive projects. Mechanical spring‑return fail‑safe is optional upon request at higher cost. Note: standard AC synchronous motor version cannot achieve electronic fail‑safe reset.

FAQS:
1.Q: What fail-safe power-off closing options are available for this damper actuator?
A: Two custom options: DC geared motor + supercapacitor electronic reset (low cost) or mechanical spring return (higher cost). Standard AC synchronous motor version cannot support electronic fail-safe.
2.Q: What is the difference between supercapacitor reset and spring return fail-safe?
A: Supercapacitor solution uses stored electric energy, cost-effective for general HVAC. Spring return relies on mechanical spring force, more reliable for mandatory fire safety applications.
3.Q: Which projects suit the supercapacitor power-off closing actuator?
A: Ideal for cost-sensitive commercial HVAC ventilation. Not recommended for smoke control systems requiring mechanical spring compliance.
4.Q: What voltage options are available for this damper actuator?
A: AC24V~AC230V for standard models; DC power supply required for the supercapacitor fail-safe customized version.
5.Q: Can the actuator be mounted in any orientation?
A: Yes, standard mounting in any position. For supercapacitor customized units, please follow installation manual.
