Daikin S25FD180300 Manual Fresh Air Damper – 15-25 Ton, 25% Manual Fresh Air
Simple, code-compliant fresh air addition for large systems
The Daikin S25FD180300 is a manual fresh air damper sized for 15-25 ton packaged rooftop units. It allows for up to 25% outdoor air to be brought into the system—helpful for ventilation and maintaining indoor air quality when required by building codes.
Because it’s manual, there’s no actuator needed, which simplifies installation and helps reduce initial cost. It’s built with durable materials, sized appropriately, and includes features to match Daikin rooftop units structurally.
Features & Benefits
- Fits 15-25 ton Daikin DBC/DBG/DCG/DCC model rooftop units
- Provides 25% steady fresh air intake
- Rectangular, downflow style damper
- Manual adjustment (slide damper) for simplicity and reliability
- Durable build for outdoor rooftop use
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.
