The A4 is designed for low water usage AND tight spaces, typically found in apartments, boats & recreational vehicles. 

How it Works

  • Rated 23 Lpm for low water usage 'whole of apartment'
  • 4 stage filtration (NSF 42 Certified for 200,000 L) for Chlorine reduction
  • NSF 55B Certified UV dosage delivered by 32 watt UV lamp to sterilize the reproductive organs of ALL FORMS of 'living nasties' (bacteria & viruses)
  • Compact design for installation in tight spaces 



Simple as 1 2 3

  1. Hang on the two SS brackets (supplied) 
  2. Connect the inlet /outlet 
  3. Plug in 



  • All components mounted on a heavy duty SS frame
  • UVC 32 watt lamp: Dosage exceeds Public Health level of 16mJ/cm2 
  • Four Standard 10" filters with Stainless Steel sumps
  • Two glycerine filled pressure gauges that indicate the state of your pump / cartridges 
  • NSF 42 Cartridges: 1m Meltblown (silts/mud); 3 x KX Carbon (Chlorine reduction) 
  • 1/2" Piping Unions: rubber washer sealing (no thread tape) for ' inlet to filter' 'filter to UV chamber' 'UV chamber – reduces leaks. 
  • SS pipe fittings; 1/2" BSP valves & Union connections (F); 

Shipping & Installation

    • Shipping Dimensions: 20kg; 770x610x220  cm
    • Frame Dimensions: 640x580x170 cm
    • Fix the two SS brackets and hang the system over the brackets
    • Do not mount close to ground. Eye level for top of system makes for easier servicing 
    • Inlet and outlet pipes to 1/2"



Annual servicing is inexpensive with lamps and cartridge readily available online from us.

  • Annually: Clean quartz sleeve, refit with new seals; Replace 24 watt lamp.
  • Annually: Replace cartridges 



Should you get sick

  1. Check your cartridges to make sure that no water is bypassing with debris that allows 'shadowing'
  2. Remove & check the sleeve for clarity; clean or replace
  3. Replace the lamp
