Units offered here use standard 120 volt power supplies. For 220V options, see our separate catalog.
“Big Boy” units use standard-sized high flow vessels (known in the industry as 20" Big Blue) that are capable of treating up to 15 gallons per minute.
These units are built with full-flow double-sized “big blue” vessels and accept jumbo-sized 4.5" x 20" cartridges and can be purchased as UV lamp only or lamp with sediment and/or carbon block filter.
Big Boy units come with 1.5" ports. These are tough, heavy duty units built to deliver very clean, bacteria-free water.
Available in single, double, and triple formats with UV only (single), UV plus sediment (double), and UV plus sediment and carbon block (triple).
Large residential whole house or light industrial systems for high flow situations where up to 15 gallon-per-minute flow rate is needed. 1.5" ports.
