Manufactured in polypropylene plastic fitted with a 60 psi pressure gauge but the filter is rated up to 80psi.  If fitted on a higher pressure water supply, a pressure reducing valve should be installed prior to the filter.

 The filter takes
12 x 40" pleated filter elements at 1 micron absolute. The maximum water flow rate unit is 1000 litres per minute,  however it is best to operate at less than 500 l/min to prolong the duty cycle.   If the turbidity of the water is less than 0.5 NTU then you may expect up to 1 year of life before the elements need to be changed.  In more turbid water, the flow will be restricted, and replacement / cleaning frequency of the filter elements may be increased.

Our cartridge filters are used with 1 micron filter elements to provide a complete barrier to oocysts of the parasite cryptosporidium and giardia.

Applications include;          

                                       

  • connection to mains water supply for municipal building

  • connection to influent water supply of swimming pools and spas

  • treatment of seawater for marine and freshwater fish hatcheries
