Detailed Core Information of Domnick Hunter 025AAR Filter Element
025AAR is a composite functional filter element for compressed aftertreatment systems from Domnick Hunter (now part of the Parker Hannifin Corporation). It belongs to the AO/AA/ACS/AR series as an oil water removal filter, primarily used to simultaneously remove oil and moisture from compressed air. The following is a compilation of technical details and practical information:
I. Core Functions and Technical Parameters
Composite Filtration Performance
025AAR combines dual functions of oil and water removal:
Oil Removal: Intercepts liquid oil mist and gaseous oil molecules, with a filtration precision of ≤.01μm and a residual oil content that can be reduced to 0.003ppm;
Water Removal: Efficiently intercepts gaseous water molecules and liquid condensate reducing the dew point temperature to **below -40°C**, meeting the Class 1 (highest grade) compressed air cleanliness requirements of the ISO8573-1:010 standard.
Structural and Performance Advantages
It adopts deep-bed pleated technology, increasing the filtration area by 450% compared to traditional filter elements, significantly the simultaneous interception efficiency of oil and moisture; it features a built-in oleophobic and hydrophobic coating to prevent oil and water from adhering and clogging, reducing system pressure loss, and extending filter element's service life to 12-18 months.
