Download Data Sheet here

The WSA4N 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 

Can be mounted outside provided the System is fitted with an optional All Weather Cover and ambient temperatures do not drop to freezing level

Features

• 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.
