The iFilters bodies are manufactured from high-grade ductile iron, allowing a pressure rating of 180 PSIG in ambient conditions. The filters feature a 5-micron cellulose pleated element; its large section contributes to a minimal pressure drop at typical flow rates. The filter element is long and pleated, allowing a large surface area, facilitating prolonged use. The filters have female threads on both sides; one side is a union-style fitting for easy installation and removal, which seals on a buna (std) o-ring. The filters also have an anodized metal nameplate with UV and chemical resistance and embossed with a unique serial number. The pressure ratings on the filters can be installed at the meter set’s inlet side, affording protection to the regulator, valve, meter, and customer’s appliances.
