Daikin S25MFD180300 Motorized Fresh Air Damper – 15-25 Ton
Automated fresh air control with actuator support
The S25MFD180300 is the motorized version of the fresh air damper for 15-25 ton rooftop units. The damper opens when the indoor blower runs (or per controller) and closes off when blower stops, delivering fresh air only when system is active—helping avoid wasteful leakage.
Its motorized actuator makes it suited for systems that integrate with building automation or have operational cycles that can benefit from timed fresh air introduction. The rugged design and appropriate sizing help ensure long service life even under challenging rooftop conditions.
Features & Benefits
- Motorized damper for 15-25 ton units
- Automates fresh air control—open/close per system demand
- Simplifies integration with controls and schedules
- Reduces energy loss due to constant open dampers
- Built for durability and compatibility with large Daikin rooftop units
Who installs the AC unit after I purchase it?
ACDirect does not yet provide installation services directly. However, most of our customers successfully arrange installation through local licensed HVAC contractors. These systems are designed for professional installation and typically include the components your installer will need.
Here’s how it works:
- Hire a licensed HVAC technician in your area
- Use platforms like Angi, Thumbtack, or a local HVAC directory to find reliable professionals
- Confirm your installer is experienced with the system type you’re purchasing
Note:
Please be aware if you choose to install HVAC equipment yourself and don’t possess proper HVAC licensing, you will void the manufacturer’s factory warranty. If you are capable of a factory-compliant installation yourself, you will need a licensed HVAC contractor to sign off on your work, fully confirming factory-compliant workmanship.
