Filtration & Pumping Commercial Ltd (New Zealand) now manufactures the full range of FPC / Atlas Pressure Diatomaceous Earth Filters in 100% T316 Stainless Steel. No protective coating is required and there is no internal corrosion. FPC believes the filters are more cost-effective and longer-lasting than other kinds. Two filters have been installed at the new Genesis Energy Recreation Centre in Masterton, New Zealand, an FPC PCT 100 filtering the Spa Pool and a PCT 80 for the Toddlers Pool.
