Key Features
- OEM Genuine Viqua Replacement: Designed and built specifically for the Viqua Arros 9 and Arros 9-V UV systems for reliable fit and performance.
- Integrated Lamp & Quartz Sleeve: The lamp is sealed inside a high-purity quartz sleeve, protecting it from water while allowing maximum germicidal UV-C light transmission.
- Long Life UV Output: Provides approximately 9,000 hours (≈ 1 year) of effective UV-C disinfection — replace annually for best performance.
- Complete Kit: Includes UV lamp, quartz sleeve and O-ring for proper sealing and installation.
- Maintains System Efficacy: Ensures your Arros system continues to inactivate bacteria and other pathogens effectively at its rated flow.

- Viqua Arros 9
- Viqua Arros 9-V
- Variants listed under Arros 9 family (such as integrated point-of-entry models that use the same lamp)
✔ Always check your system model before ordering to ensure a correct match.
Specifications
- Part Number: VA09LU
- Lamp Unit Type: Integrated UV lamp & quartz sleeve combo unit
- Recommended Replacement: After ~9,000 hours (~1 year) of operation to maintain UV dose and system performance.
- Includes: UV lamp, quartz sleeve, and O-ring(s)
- Wavelength: Germicidal UV-C (standard for water disinfection)
- Application: Whole-house or point-of-entry UV systems treating microbiological contaminants
Why Replace Both Lamp & Sleeve Together
In UV systems like the Arros 9, the lamp generates the germicidal UV light while the quartz sleeve transmits it efficiently into the water. Over time:
- The UV lamp’s output decreases, even if it still glows.
- Scale, mineral deposits, or staining on the quartz can block UV light, reducing disinfection effectiveness.
Replacing both parts together ensures maximum UV transmission and microbial inactivation performance.
Maintenance & Installation Tips
- Annual Replacement: Swap the VA09LU lamp and sleeve after about one year of use or when system indicators prompt service.
- Keep Quartz Clean: During replacement, clean any mineral scaling from around the sleeve and inspect O-rings.
- Handle Gently: Avoid touching the quartz sleeve with bare hands — oils can reduce UV transmission.
- Depressurize First: Always shut off water supply and drain pressure before servicing.
Applications
Perfect for maintaining safe, chemical-free water disinfection in:
- Residential homes (whole-house or point-of-entry UV systems)
- Cottages and seasonal homes
- Well water UV treatment setups
- Light commercial UV disinfection needs
