Pentair PuraShield UV+Ozone Replacement Lamp

Pentair PuraShield UV+Ozone Replacement Lamp (Part No. 800854)

Keep your PuraShield UV+Ozone system performing at peak efficiency with this genuine Pentair replacement lamp. The PuraShield lamp produces dual-wavelength UV output — 254nm for germicidal treatment and 185nm for ozone production — ensuring your pool or spa water stays clear, sanitised, and properly oxidised.

Pentair recommends replacing the UV lamp annually to maintain optimal system performance, as lamp intensity degrades over time even when the lamp is still illuminated.

• Genuine OEM Pentair replacement lamp
• Dual-output: 254nm (germicidal) + 185nm (ozone production)
• Compatible with PuraShield UV+Ozone systems
• Part Number: 800854
• Annual replacement recommended

Frequently Asked Questions

Which PuraShield systems is Part 800854 compatible with?

Part 800854 is the genuine replacement lamp for Pentair PuraShield UV+Ozone (PSUV-87-O3) systems. If you are unsure about compatibility, check your system's model number or contact us before ordering.

How often should I replace my PuraShield UV lamp?

Pentair recommends replacing the UV lamp every 12 months (approximately 9,000 hours of operation). Even if the lamp appears to still be lit, UV output degrades significantly over time, reducing sanitisation effectiveness.

How do I know when my lamp needs replacing?

Your PuraShield system features a digital lifetime meter that tracks lamp hours. Replace the lamp when it reaches its rated hours, or if the sight glass shows reduced or no glow during operation.

Is this a genuine Pentair part?

Yes — Part 800854 is a genuine OEM Pentair lamp, not an aftermarket substitute. Using genuine parts ensures your system operates within warranty and maintains rated performance.
