Aprilaire 80LC Replacement Steam Canister & O-Ring for 800LC
A genuine replacement steam canister (with O-ring) used in the Aprilaire 800LC steam humidifier to generate steam for whole-home humidity.
Key Features:
- Genuine Aprilaire replacement steam canister for the 800LC steam humidifier
- Includes O-ring for a leak-proof seal
- Low-conductivity canister optimized for water conductivity less than 300 uS/cm or when the steam humidifier is installed at 120 VAC
- Should not be used with softened water
- Recommended replacement schedule: once per year
- Box contents: 80LC steam canister and 5258 O-ring
Compatibility & Applications:
- Compatible model: Aprilaire 800LC
- Intended for low-conductivity water applications as defined by Aprilaire
- Must only be used where the manufacturer specifies this exact part number: 80LC
Installation & Operation Notes:
- Installation should be performed by a qualified HVAC professional or experienced service technician
- Follow the Aprilaire 800LC service/installation manual for safe shutdown, canister removal/installation, and proper O-ring seating
- Important manufacturer guidance: if the humidifier is draining too frequently, water conductivity may be too high; Aprilaire notes changing to the Model 80 canister can reduce drain frequency
Maintenance & Troubleshooting:
- The canister is a routine service item and is described by the manufacturer as the component responsible for generating steam in the humidifier
- Replace on the recommended interval (once per year) to maintain performance
- If steam production is poor in low-conductivity water, the 80LC is intended for those conditions; if frequent draining occurs, conductivity may be too high for the 80LC (per manufacturer guidance)
- If conductivity specifications are needed in EC (microSiemens) and not shown, Q&A guidance recommends contacting Aprilaire directly for confirmation
User Reviews & Q&A Summary:
- Common themes highlight that the 80LC resolves performance issues in low-conductivity/soft-water situations, restoring normal steam output when the standard canister struggles
- Many reviews describe a quick, straightforward swap (often mentioned as a short install) that gets the humidifier running again
- Buyers frequently mention strong value/availability compared with other sources, along with positive shipping and service experiences
