FILTER OIL FORMULATION

摘要

A filter oil composition and a method for removing airborne molecular contaminants from air are provided. The composition includes a first portion comprising paraffmic oil by volume of the composition, a second portion comprising polyalphaolefm (PAO) by volume of the composition, and a third portion comprising red dye by volume of the composition. Applying the filter oil composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing filtration of air passing through the filter. The composition generally is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity at a normal operating temperatures of an automobile engine. In an embodiment, the composition comprises 96.74% paraffmic oil by volume, 3.20% polyalphaolefm (PAO) by volume, and 0.06% red dye by volume. A viscosity of the composition at 100 degrees- C ranges between substantially 7.2 and 7.6 centistokes (cSTs).
