Filter oil formulation
A filter oil composition and a method for removing airborne molecular contaminants from air are provided. The composition includes a first portion comprising paraffinic oil by volume of the composition, a second portion comprising polyalphaolefin (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% paraffinic oil by volume, 3.20% polyalphaolefin (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).
1. A method for removing airborne molecular contaminants from air, comprising:
configuring a filter material to remove airborne molecular contaminants from an airstream passing through the filter material;
formulating an air filter oil composition for application to the filter material, the air filter oil composition being configured to enhance air cleaning properties of the filter material;
supporting the filter material such that the airstream is directed through the filter material; wherein a support comprises at least one housing portion and at least one mount portion, wherein the mount portion includes a first set of panels level with a top edge of the housing portion and a second set of panels being a distance below the top edge of the housing portion, the panels arranged in alternating manner wherein the mount portion comprises: (i) a plurality of parallel ridges of varying depths having a first height disposed along a surface of the mount portion, and (ii) a plurality of depressed portions disposed along the surface of the mount portion; wherein one of the depressed portions is disposed between two of the parallel ridges, and the parallel ridges have a top surface that is not coplanar with a top surface of the depressed regions; and wherein the parallel ridges and depressed portions of the mount portion are configured for mounting; and
cleaning the filter material periodically so as to remove entrapped contaminants.
2. The method of claim 1 , wherein formulating comprises providing a first portion including paraffinic oil by volume of the composition, a second portion including polyalphaolefin (PAO) by volume of the composition, and a third portion including red dye by volume of the composition, such that application of the composition to a cotton air filter material causes tackiness throughout the air filter material, thereby enhancing filtration of the airstream.
3. The method of claim 2 , wherein the composition is substantially non-reactive, has an excellent oxidation stability, possesses good thermal stability, and retains a suitable viscosity within a temperature range typical of an operating automobile engine.
4. The method of claim 2 , wherein the composition comprises 96.74% paraffinic oil by volume, 3.20% polyalphaolefin (PAO) by volume, and 0.06% red dye by volume.
5. The method of claim 2 , wherein the composition has a viscosity at 100 degrees-C ranging between substantially 7.2 and 7.6 centistokes (cSTs).
6. The method of claim 1 , wherein configuring comprises positioning at least one layer of cotton gauze between two epoxy-coated aluminum wire screens so as to support the filter material during filtering of the airstream.
7. The method of claim 1 , wherein supporting comprises positioning the filter material within an air intake of an internal combustion engine.
8. The method of claim 1 , wherein supporting comprises positioning the filter material within a ventilation system which circulates air within an enclosed space.
9. The method of claim 1 , wherein cleaning comprises removing the filter material from the airstream, using a solvent to remove the air filter oil composition, flushing contaminants and the solvent from the filter material by way of a water hose, allowing the filter material to dry, and uniformly applying the air filter oil composition to the filter material.
