Posted on: 09/04/2026

Honeywell MS4609F1010/B 230V damper actuator. Featuring a reliable 9Nm spring return mechanism without auxiliary switches, it offers a cost-effective and fail-safe solution for AC-powered ventilation systems. Distributed by DLK Vietnam.

Honeywell MS4609F1010/B: Professional 230VAC Damper Actuator Solution

For engineering projects where a 24V infrastructure is not available, direct high-voltage actuators provide the most efficient installation path. The Honeywell MS4609F1010/B is a high-performance spring return actuator designed specifically to operate on 230VAC power, eliminating the need for step-down transformers. This robust device is imported and officially distributed by DLK TRADING SERVICE COMPANY LIMITED.

Power Efficiency with Direct 230VAC Input

The primary advantage of the MS4609F1010/B is its compatibility with standard AC power lines. For M&E contractors, this translates to:

Reduced Costs: No requirement for additional power converters or specialized low-voltage wiring.
Simplified Cabinets: Smaller control panels as bulky transformers are removed from the system design.
Versatile Retrofitting: The ideal candidate for upgrading older systems or for standalone installations in mechanical rooms.

Streamlined Design: Focused on Core Performance

The MS4609F1010/B model is the standard version within the series, intentionally designed without integrated auxiliary switches. By focusing purely on the On/Off drive function, the unit achieves a more competitive price point and a simplified wiring process, reducing potential points of failure while maintaining a reliable 9Nm torque.

Fail-Safe Reliability with Spring Return Technology

Operating on high voltage does not compromise safety. The Honeywell MS4609 damper actuator features a heavy-duty mechanical spring return system.

Powered State: The motor drives the damper open while simultaneously tensioning the internal spring.
Power Loss: The spring automatically releases its energy, driving the damper to its safe position in less than 20 seconds.

This fail-safe action is mandatory for protecting AHU coils from freezing and preventing smoke migration during fire emergencies.
