Fiberglass Ac Filters

fiberglass ac filters
  • A woollike mass of glass filaments, used in insulation
  • A composite material made by embedding glass fibers in a polymer matrix. May be used as a diffusing material in sheet form, or as a standard sash and frame element.
  • A reinforced plastic material composed of glass fibers embedded in a resin matrix
  • a covering material made of glass fibers in resins
  • A textile fabric made from woven glass filaments
  • US spelling of fibreglass
  • A porous device for removing impurities or solid particles from a liquid or gas passed through it
  • A screen, plate, or layer of a substance that absorbs light or other radiation or selectively absorbs some of its components
  • (filter) remove by passing through a filter; "filter out the impurities"
  • (filter) an electrical device that alters the frequency spectrum of signals passing through it
  • A device for suppressing electrical or sound waves of frequencies not required
  • (filter) device that removes something from whatever passes through it
  • actinium: a radioactive element of the actinide series; found in uranium ores
  • .ac is the Internet country code top-level domain (ccTLD) for Ascension Island. It is administered by NIC.AC, a subsidiary of the Internet Computer Bureau based in the United Kingdom.
  • The chemical element actinium
  • alternating current: an electric current that reverses direction sinusoidally; "In the US most household current is AC at 60 cycles per second"
fiberglass ac filters - (12 Pack)
(12 Pack) - 10x24x1 EcoAire (12 Pack)Disposable (MERV-7) Polyester Coated Fiberglass Air Filter
(12 Pack) - 10x24x1 EcoAire (12 Pack)Disposable (MERV-7) Polyester Coated Fiberglass Air Filter
The EcoAire poly-coated fiberglass filters are constructed of MERV 7, patented polyester coated fiberglass and are encased in a sturdy, eco-friendly, cardboard frame. Eco-Aire disposable filters are the most efficient fiberglass filters available in the industry today. These filters capture airborne particles/allergens between three to ten microns in size such as particles that carry viruses and bacteria, pollen, mold spores, fine dust and pet dander. The filter media will not promote the growth of bacteria, mold, mildew, or fungi in normal operating environments, and has not been chemically treated. Each filter lasts up to one month and should be changed and disposed of regularly. A 12-pack will provide up to a year's supply of cleaner air. This product is listed and rated by Underwriter's Laboratories as U.L. Class 2.

Establishing the center line.
Establishing the center line.
Using this string depicted centerline, I made sure that the port and starboard topside sheer lines were equally distant from the keel line. Having rigid garage walls were a big help in keeping things braced until the bulkheads were installed. Using a hand plane, I fussed with the bulkheads to get a good but not perfect fit with the hull side. Then I read submissions to boat building forums which claim that in an epoxied wood joint, wood should not touch wood, instead leave an air gap between panels I presume so the fllets are locked together. I have read of drilling a 1/2" hole through a bulkhead so a thin stip of fiberglass can run between the filets/fiberglass on each side of a panel. I have also read of tapering the edge of a plywood bulkhead so the fiberglass on a seam is in contact with multiple laminations not just the top lamination. If I were building a bluewater or high speed boat I would search for empirical evidence to substantiate the above opinions, and do some destructive joint testing. Since this is my first serious boat building experience, I have no qualifications to dispute recommended methodologies and instead rely on a gut feel. Today I continue my practice of striving for a reasonably good bulkhead fit (there is usually some fillet squeeze out that travels to the other side of the bulkhead seam), installing a properly radiused filet and using a layer of 17 oz 45 degree bias bi-axial fiberglassed tape on each side of a major bulkhead. My recollection from stich and glue books from authors such as Devlin is a comment that stich and glue is forgiving in regards to gaps between panels. I don't recall a specific recommendation to leave an air gap in the panel seams so more epoxy can be used in a joint. It seems counter-intuitive to substitute more glue for less wood. I do seal the plywood edges with epoxy before I do the final fitting of the bulkheads. Before installing and with the bulkhead lying flat, I coat each bulkhead with epoxy but tape off the area where the fiberglass tape will land to avoid a "secondary bond" situation. Coating the bulkheads before installing should expedite the process of later painting these panels. I also rough up with 60 grit sand paper the wood areas to be fiberglassed. I believe that by carefully filtering advice, relying on my experience, and using common sense, I expect to have a successful and very enjoyable Bluejacket build. I have given up worrying what is the "right" way to execute a particular task since for most issues there is no strong concensus among boat builders and we tend to get rabid in a debate....just like politics and religion. Want to to have some fun, go onto a boat building forum and ask, "Is it ok to use fiberglass mat with epoxy". The Bluejacket has a modest top speed and I suspect that there is no single builder mistake that can cause catastrophic failure other than a mistake in installing the Bluejacket's fuel, AC electrical system or steering systems. These are three areas that we must ensure we are doing it the "right" way. USCG regulations on fuel systems meets my definition of the "right' way".
