Product Introduction
When your smoke control system requires unwavering force to operate larger, heavy-duty dampers, precision and power are non-negotiable. The Xiamen Hysen 5Nm Fire Smoke Actuator delivers exactly that. Designed for demanding commercial and industrial HVAC applications, this actuator provides the higher torque necessary to ensure positive closure of larger damper blades in the event of a fire. As your trusted ODM manufacturing partner, we offer this industrial-grade solution with the same commitment to reliability, customization, and global standards.
Key Features & Technical Advantages
Our HY-DF-SF05 series builds upon our proven design with enhanced power for more critical applications.
Higher 5Nm Torque Output:
Generates 66% more force than our 3Nm model, confidently operating dampers up to 1m² in size. This ensures reliable performance in larger ductworks and against higher air pressures.
Faster Spring-Return Action:
Engineered for rapid response, the actuator resets to its fail-safe position in under 70 seconds for standard operation and a swift under 20 seconds for emergency spring return, prioritizing occupant safety.
Proven Dual-Voltage Design:
Offers seamless integration into any building infrastructure with both low-voltage AC/DC 24V and direct line AC 100-240V options, providing installation flexibility worldwide.
Optional Integrated Thermal Failsafe (DST Type):
Select models feature the SAF72 thermal sensor, providing a critical local backup activation system that triggers independently of the main fire panel if extreme heat is detected.
Industrial-Grade Durability:
Maintains a robust IP54 enclosure rating, protecting internal components from dust and moisture in harsh mechanical environments. Built to perform consistently within a wide temperature range (-20°C to +50°C).
Clear Diagnostics & Control:
Features a manual override for easy testing and commissioning, plus a mechanical position indicator for instant visual confirmation of the damper's status.

FAQ Section
Q1: When should I choose a 5Nm actuator over a 3Nm model?
The 5Nm model is essential for larger damper blades (typically up to 1m²) or in systems with higher static pressure where more force is required to achieve a tight, reliable seal. It's the preferred choice for commercial and industrial applications, while the 3Nm model is ideal for smaller, residential or light commercial dampers.
Q2: Is the faster 20-second spring return time a significant advantage?
Absolutely. In a fire emergency, every second matters to prevent smoke spread. The faster 20-second reset time on our 5Nm actuator ensures critical dampers close more rapidly, helping to compartmentalize fire and smoke faster and potentially providing vital extra time for occupant evacuation.
Q3: Can we request samples to test the performance and quality?
Yes, we strongly encourage it. We are confident in our manufacturing quality and welcome international B2B partners to request working samples for performance testing and evaluation before committing to a large bulk order.
Q4: What is your warranty policy for these actuators?
We stand behind the quality of our products. Our fire smoke actuators come with a standard 24-month warranty against manufacturing defects, giving our distribution partners and their end-users confidence in the product's longevity and reliability.
Q5: Do you offer custom branding and packaging for ODM partners?
Yes, we do. Custom branding (including product labeling and packaging) is a standard part of our ODM service. We can align the product's appearance perfectly with your brand identity for your market.
