PerfectPleat ULTRA

The PerfectPleat ULTRA filter is designed to consistently increase efficiency throughout the service life of the filter. The PerfectPleat ULTRA filter has approximately 25% more media than our standard capacity filter, and also incorporates an antimicrobial. The antimicrobial is applied to the media to preserve the integrity of the media throughout the filter’s useful life by inhibiting microbial growth. PerfectPleat ULTRA filters have an initial G4 (EN779:212) rating respectively, but the efficiency increases significantly when dust holding begins. PerfectPleat ULTRA filters have distinctive self-supporting characteristics that allow a pleating pattern, which promotes airflow and maximizes dust holding capacity (DHC). The PerfectPleat ULTRA filter is ideal for applications where pleated filters are currently in use, and higher efficiencies are desired or required. It is also suited to high moisture conditions where bacterial growth may be likely to occur on air filters.

Superior Design and Construction

The perimeter frame is constructed from the highest wet-strength beverage carrier board, securely bonded to the media pack. The 19 mm model employs three supporting straps on the air-entering and air-leaving sides of the filter to control pleat spacing and support the media pack in the perimeter frame. Support straps on the air-entering side are used in combination with uniquely designed pleat stabilizers on the air-leaving side of the 44 mm model to provide additional strength. The support straps and pleat stabilizers ensure integrity against turbulent airflow. The 44 mm filter resists crushing and abuse, and provides excellent lateral stability for installation in side-access systems.
