Abstract
A pre-filter kit and related method of use with an air filter associated with an intake of a machine is provided. The kit can include a sheet of pre-filter material, an adhesive component, such as an adhesive on a release liner, and one or more optional bands. The method can include: measuring a height of the air filter, cutting the sheet of pre-filter material so that the sheet includes a top edge and a bottom edge separated from one another by the height, as well as a first end and an opposing, second end; applying adhesive to the first end; and wrapping the sheet around the air filter so that the first end overlaps the second end to secure the first end to the overlapped portion of the sheet. The pre-filter is secured to the air filter so as to impair dirt, dust and debris from entering the air filter.
Claims20
A method of using a pre-filter with an air filter comprising:
- providing an air filter configured for installation on an air intake of a machine, the air filter including a top, a bottom and central portion therebetween, the air filter being of at least one of a cylindrical shape and a frustoconical shape, the air filter having an interior and an exterior, with a filter material therebetween, sufficient to allow air to flow from the exterior to the interior, the air filter having a first height between the top and the bottom of the air filter;
- providing a sheet of pre-filter material constructed from a woven mesh having a plurality of interweaved strands, each strand having a substantially circular cross section;
- cutting the sheet of pre-filter material so that the sheet includes a top edge and a bottom edge separated from one another by the first height, as well as a first end and an opposing second end;
- providing a release liner having disposed thereon an adhesive;
- engaging the release liner against the first end so as to apply the adhesive to the first end;
- removing the release liner from the first end with the adhesive remaining on the first end;
- wrapping the sheet of pre-filter material around the air filter central portion, so that the top edge is adjacent the top of the air filter, and the bottom edge is adjacent the bottom of the air filter, and so that the first end overlaps an overlapped portion of the sheet, with the adhesive on the first end engaging the overlapped portion of the sheet so as to secure the first end to the overlapped portion of the sheet;
- elastically expanding a first band;
- placing the first band over the sheet of pre-filter material adjacent the top edge;
- releasing the first band so that the first band squeezes the sheet of pre-filter material against the exterior of the air filter adjacent the top edge;
- elastically expanding a second band;
- placing the second band over the sheet of pre-filter material adjacent the bottom edge;
- and
- releasing the second band so that the second band squeezes the sheet of pre-filter material against the exterior of the air filter adjacent the bottom edge,
- whereby the sheet of pre-filter material is secured to the air filter so as to impair dirt, dust and debris from substantially engaging the air filter.
A method of using a pre-filter with an air filter comprising:
- providing an air filter configured for installation on an air intake of a machine, the air filter including a top, a bottom and central portion therebetween, the air filter having a first height;
- providing a sheet of woven pre-filter material;
- cutting the sheet of woven pre-filter material so that the sheet includes a top edge and a bottom edge separated from one another by the first height, as well as a first end and an opposing second end;
- applying adhesive to the first end;
- and
- wrapping the sheet around the air filter central portion, so that the top edge is adjacent the top of the air filter, and the bottom edge is adjacent the bottom of the air filter, and so that the first end overlaps an overlapped portion of the sheet, so as to secure the first end to the overlapped portion of the sheet,
- whereby the sheet of woven pre-filter material is secured to the air filter so as to impair dirt, dust and debris from substantially engaging the air filter.
A pre-filter kit adapted for installation on an air filter, comprising:
- a sheet of pre-filter material constructed from a woven mesh having a plurality of interweaved strands, each strand having a substantially circular cross section, the sheet adapted to be cut so that the sheet includes a top edge and a bottom edge separated from one another by a first height, as well as a first end and an opposing second end;
- a release liner having disposed thereon an adhesive, the adhesive adapted for application to the first end;
- a first band adapted for placement adjacent the top edge;
- and
- a second band adapted for placement adjacent the bottom edge;
- whereby the sheet of pre-filter material is configured for securement to the air filter so as to impair dirt, dust and debris from substantially engaging the air filter.
