Trojan UVMax Model F4 ultraviolet (UV) water purifier

The latest generation Trojan UVMax Model F4 is a designed for large homes with very high water demands where water flow rates may reach as much as 25 gallons per minute (average shower flows at about 2 GPM). It is also popular for light industrial applications or where an extra high UV dose is desired at lower flow rates to kill stubborn contaminants. The Model F4 replaces the Trojan UVMax Model F which was retired in late 2008.

The Trojan UVMax Model F4 can be equiped with an optional UV intensity monitor. The UV intensity monitor continuously monitors the intensity of the UV light to ensure that the water is receiving an adequate dose of UV light to kill the bacteria, viruses, etc. The use of a model with a UV intensity monitor is generally recommended where a known e.coli or other serious problem is present or the feed water parameters may cause problems with UV tramsmittance from time to time (sediment flushing, iron or hard water scale build-up on the UV sleeve etc.). The UV intensity monitor MUST be purchased at the same time as the unit - it CANNOT be added at a later date. When equiped with the UV intensity monitor, it is refered to as the Model F4+ (PLUS).

Second, the Trojan UVMax Model F4 can also be equiped with an optional solenoid emergency shut-off kit. For more information on the emergency shut-off kit, CLICK HERE.
