Description 20-inch Jumbo Filter Housing filters are perfect for removing sediments, rust, silt and loose particles from rainwater, municipal water or well-point/ borehole water. Install a carbon block to improve the taste and odour, and remove chlorine and contaminants. The filtered water can then be used safely to supply washing machines, geysers, and toilets Big blue filters are intended for fine filtration, and limits apply to water quality and flow rates. Have your water tested before installing a big blue filter to ensure that it is the right solution for you. It is important to note that the volume of water put through the unit, as well as the quality of the water, will greatly influence the lifetime of the filters. - Max flow rate: 2500 l/h - Port size: 25mm (1inch) female - Air/pressure release valve (red button) - Suitable for 20x4.5inch filter cartridges and carbon blocks (cartridges to be purchased separately) - White powder-coated bracket with screws for mounting against a wall - Plastic spanner for opening and closing filter.
