The "Dante" cartridges for Carron are manufactured by Cuno/3M group and whilst our filters do not carry original Carron branding, we supply the AP2-C401S (which superceeded the AP2-C305 range as of January 2011). This cartridge has the same fitment as that used by Carron and offers the same filtration performance, just at a more economical price.The AP2-C401-S removes chlorine, sediment, benzene, dichlorobenzen, and toxaphene. It also includes a scale inhibitor designed to assist in protecting equipment from failiure due to limescale build-up, and bacteriostatic media ensuring cartridge safety through it's recommended service life. This is a very common filter in commercial markets. If you are looking for quantity pricing (12+ cartridges per order) to service multiple sites and machines then please contact us for additional information, stating your requirements. Service life: 3000 litres or 6 months, whichever comes first. Cuno Part: AP2-C401-S
