We supply string wound polypropylene cartridges, melt blown PP (spun) cartridges, pleated polyester/PP cartridges and activated carbon block cartridges. All are available in 1, 5, 10, 20 and 50 micron ratings and standard 10", 20", 30" and 40" lengths to fit standard filter housings.
A 5 micron melt blown or string wound polypropylene cartridge is the most common choice for RO pre-filtration, protecting the high-pressure pump and membranes from sediment. Where feed water carries fine colloids we recommend a 5 micron pleated cartridge, and carbon block cartridges are added upstream to remove chlorine that can oxidise thin-film RO membranes.
