Luminor LB5-151B Blackcomb 5.1 UV System NSF Class B 22 GPM

The Luminor LB5-151B BLACKCOMB 5.1 is a UV water treatment system certified to NSF/ANSI 55 Class B. With its built-in flow restrictor it is rated at 22 GPM (83.3 L/min) at a UV dose of 16 mJ/cm² and 70% UV transmittance. Class B systems provide supplemental bactericidal treatment of water that is already considered safe to drink, such as treated municipal water, reducing normally occurring non-pathogenic nuisance microorganisms. It uses a 50-watt UV lamp in a polished 304 stainless steel chamber, with 1-inch MNPT connections.

How it works and alerts you

The full-colour LCD BLACKCOMB 5.1 controller shows remaining lamp life, diagnostics and fault messages, gives a yellow caution 30 days before the lamp expires and an audible and visual alarm at lamp failure, and shows a service reminder every 6 months. Its Infinite Expandability Port (IEP) accepts an optional RS-B2.5 UV intensity sensor and Luminor modules such as MOD-SOL, MOD-420, MOD-RAM, MOD-SHERPA and the LFM flow meter. The controller reports lamp status; it does not by itself confirm the water is safe to drink, so Luminor recommends testing your water for microbiological contaminants regularly.

Class B vs. Class A

Class B is not intended for water with known contamination. For untreated well water or other microbiologically unsafe supplies, choose an NSF/ANSI 55 Class A system such as the BLACKCOMB-HO 6.1 LBH6-251A or LBH6-401A.

Why the rating is 22 GPM

The standard LB5-151 is rated 15 GPM at 30 mJ/cm² and 95% UVT. The Class B rating uses a lower dose (16 mJ/cm²) at lower water clarity (70% UVT), and the integral flow restrictor holds flow to the certified 22 GPM. Do not remove the flow restrictor.
