 Product Description

NSF 55 includes both Class "A" systems, which require a minimum UV dose of 40mj, for use with waters that are assumed to be contaminated, and Class "B" systems, which require a dose of 16mj. Class "B" systems are only intended to provide supplemental disinfection of non-pathogenic nuisance organisms on water supplies that are otherwise considered potable.

UVMAX E4 (18.5 GPM 120V/230V) is a Class “A” UV system.


  • Equipped to inactivate chlorine-resistant parasites such as Cryptosporidium and Giardia, harmful bacteria like E.Coli and viruses not visible to the naked eye.
  • The special lamp plug ensures that no one can power the UV lamp if it’s not in the UV chamber.
  •  With the push of a button, you can confirm the proper operation of the sensor.
  • Lamps and sleeves are assembled together for ease of handling. They can be replaced separately, in minutes and without tools.
  • The reference card outlines the most important system functions and maintenance for quick, on-the-spot questions.
  •  Indicator lights show the status of system components. Warning lights appear when system maintenance is required.
  •  The lamp timer display starts at 365 and counts down the days to annual lamp replacement. 
  •  Once annual lamp replacement is completed, press this button to restart the lamp timer.
  •  If a warning alarm sounds, simply press this button to silence the alarm.
  •  Our high output validated UV lamp is engineered to treat variable water conditions.
