Field Controls 46510800 UV-16/120 16" UV-Aire In-Duct Air Purifier (120V)
A Field Controls in-duct UV air purifier designed to install in the main supply or return duct of a forced-air heating/air conditioning system to reduce airborne microorganisms as air passes through the UV treatment zone.
Key Features
- Designed to emit UVC band light to reduce airborne viruses and microorganisms as air moves through the HVAC system
- Installs in the main supply or return duct and is intended to operate continuously (24/7)
- 16" high-efficiency UVC lamp; designed for easy lamp replacement
- Plugs into a standard 120V outlet
- Manufacturer notes UV placement can also help keep A-coils cleaner, supporting system efficiency and reduced maintenance
- Manufacturer-listed specifications include: minimum duct width 16" and system sizing 1.5 to 5.0 tons (UV-16/120)
- Included kit components (per installation manual): ballast assembly & power cord, mounting base, UV lamp, sheet metal mounting screws, instruction sheet, fiberglass duct board mounting bracket, and UVC light shield
- Replacement/service items shown for this model include a 16" replacement lamp and a ballast assembly for UV-16 (120V)
Compatibility & Applications
- Intended for closed duct systems in forced-air HVAC where the duct can accommodate the 16" UV-16/120 and meets the minimum duct width requirement.
- Must only be used where the manufacturer specifies this exact model/part number: UV-16/120 (46510800).
Installation & Operation Notes
- Installation should be performed by a licensed/qualified HVAC contractor and follow the UV-16/120 installation manual and the HVAC system's service/installation documentation.
- Key safety/placement notes from the manufacturer documentation:
- Never expose eyes or skin to UVC light; do not operate the unit outside the duct/plenum.
- Designed for a closed duct system; do not mount near supply/return openings.
- Seal duct openings in direct line of sight of UV light with approved sealing methods.
- UV light can degrade plastics not rated for UV exposure (examples given include wire insulation, flex duct, drain pans, humidifiers); maintain manufacturer-required separation and/or shielding.
- Indoor installation only; do not mount outdoors
- Handle the lamp carefully (lamp contains mercury), and avoid touching the glass portion (clean with alcohol if touched).
Maintenance & Troubleshooting
- Routine maintenance centers on lamp replacement as required; the manufacturer highlights easy lamp replacement and provides a dedicated replacement lamp for the UV-16 line.
- If performance issues are suspected, follow the manual's troubleshooting guidance and verify correct installation (proper shielding/clearances, sealed openings, correct placement).
- User feedback indicates occasional early lamp failure can occur; replacement of the lamp (and, if needed, ballast) is the typical corrective action.
Certifications & Compliance
- A cULus listing mark is shown on the manufacturer installation manual cover page for the UV-16/120 system.
