If the appliance calls for aerial dust-holding accommodation and low airflow attrition Polyfold filters can do the job. Further, these automated filters fit the bill both for applications that charge a abiding band-aid and for applications breadth a disposable advantage is required. Polyfold filters are an accomplished best for both bartering and automated use. For abiding models, Polyfold filters use either Uni-Foam or Quadrafoam media. Uni-Foam media can be acclimated central or outdoors. It is able to bear acknowledgment to damp in alfresco environments. Its cellular media anatomy serves as a brume eliminator, abbreviation access of rainwater and baptize splash. Some models with Uni-Foam media are additionally advised for appliance in accessories with bound amplitude for filtration.

Quadrafoam is open-cell polyurethane cream with a flame-retardant blanket that allows the filters to accommodated UL 94V-0 standards. Deep loading, with a ample dust-holding capacity, Quadrafoam additionally offers low airflow resistance. Polyfold disposable filters use Polyester media, which is a non-woven, non-migrating, constructed material. Produced application avant-garde accomplishment technology; it provides ASHRAE dust arrestance to 90 percent in a clarify that delivers accord and accomplished clarification performance.

In a Polyfold air filter, the media, whether Uni-Foam, Quadrafoam or Polyester, is mechanically formed, with no areas of astriction and basal distortion, into acclaim rolling pleats. The pleating produces alike airflow throughout the absolute breadth of the filter. This architecture lowers airflow attrition while abundantly accretion dust-holding capacity. The Polyfold clarify anatomy is roll-formed into a athletic jumpsuit approach fabricated of 0.40-inch blubbery 3000 alternation aluminum. The anatomy is adapted deeply to the clarify media and attached with two aluminum rivets. In addition, the air filters affection Uni-Grid support, which consists of broadcast aluminum and is about 85 percent accessible to lower airflow resistance. The 0.40-inch-thick 3000 alternation aluminum is broadcast on distinctively advised Uni-Grid equipment.

Quadrafoam, Uni-Foam and Polyester media are additionally acclimated in their own namesake air filters: the Quadrafoam, Uni-Foam and Polyester air filter. In these customs, the media ample some added specific applications. Uni-Foam filters are an accomplished best for medical, electronics, computer, telecom, datacom and general-purpose applications. Quadrafoam meets the requirements of electronics, computer, telecom, datacom, medical and general-purpose equipment, as well. With their aerial dust arrestance and low airflow resistance, disposable Polyester filters assignment awfully able-bodied in HVAC applications.
