Specialty Filters

United Filters International specialty products include No Scale Filters and Petrochemical Filters.

UFI No-Scale inhibitor consists of a well-balanced blend of food-grade organic polyphosphates. No-Scale stabilizes and inhibits the corrosion/scale process by eliminating brown water (iron oxide/hydroxide) and stopping the further build up of white scale (i.e., calcium carbonate and calcium silicate).

Liquid filter bags offer low clean pressure drop, high dirt holding capacity, and excellent particulate retention. Standard liquid filter bags are economical, disposable filter solutions manufactured in a variety of materials and a wide array of sizes and styles.

UFI Petrochemical Filters are a comprehensive line of filters and filter vessels utilized in offshore exploration and production, gas production/transmission, and petrochemical refinery applications.

UFI No-Scale inhibitor is the economical way to protect water systems against scale and corrosion. Consisting of a well-balanced blend of food-grade organic polyphosphates, No-Scale stabilizes and inhibits the corrosion/scale process. As a “threshold inhibitor”, No-Scale is slow-acting, preventing new scale from forming and loosening/softening existing scale deposits. Over time, these deposits are flushed off by the natural turbulence of the water flow.

No-Scale is compatible with galvanized, copper, and plastic pipes as well as all wetted surfaces. It will eliminate brown water (iron oxide/hydroxide) and stop the further build-up of white scale (i.e., calcium carbonate and calcium silicate).

UFI Liquid Filter Bags are a cost-effective alternative for most fluid applications. Manufactured with a wide array of sizes and styles and using several media options to insure fluid compatibility, these bags are available in 1 absolute to 1,500 nominal micron ratings and are 100% interchangeable with all industry standard #1 through #9 filter bag housings.

Used extensively in hydrocarbon and natural gas processes as well as RO pre-filters, liquid filter bags offer ease of removal while containing contaminants for proper disposal. Pleated bags provide longer service life, reduce operating cost, and cause less process downtime. Custom and standard lift handles enable simple and fast removal of spent bags. Inside to outside flow promotes easy disposals with less risk of downstream contamination during change-out.

United Filters International provides advanced filtration solutions for the petrochemical industry, ensuring the removal of contaminants that compromise efficiency, safety, and product quality. UFI offers a range of high-performance filter cartridges, coalescers, and separators designed to handle the demanding conditions of petroleum refining and chemical processing. UFI filtration systems effectively remove particulates, water, and other impurities from fuels, lubricants, and chemical feed stocks, improving operational reliability and meeting stringent industry regulations.

UFI’s product line includes depth filters (ideal for capturing fine particles and extending equipment lifespan), membrane filters (used for precise separation and purification of chemicals and solvents), coalescing filters (to efficiently remove water and emulsified contaminants from fuel and lubricants), and activated carbon filters (to eliminate organic compounds, odors, and unwanted hydrocarbons).
