Hydraulic, designed to equip pressurized filters, filter drain and other hydraulic systems. Oil intended for lubricating systems, filters, complete machines and mechanisms in various industries.Filter elements provide the highest degree of filtration efficiency for industrial, mobile, and process applications. Our filter elements are composed of micro-glass media, the most recent innovation in high performance filtration technology. Micro-glass media is inert, inorganic, and far exceeds any paper or cellulose filter element performance. Water or chemicals, which cause softening, swelling, and degradation in conventional cellulose or pleated paper filters, do not affect micro-glass media.
