Superior Design and Construction
The perimeter frame is constructed from the highest wet-strength 28 pt. beverage carrier board, securely bonded to the media pack. Support straps on the air-entering side are used in combination with uniquely designed pleat stabilizers on the air-leaving side of the 2″ model to provide additional strength. The support straps and pleat stabilizers ensure integrity against turbulent airflow. The 2″ filter resists crushing and abuse, and provides excellent lateral stability for installation in side access systems. The 4″ model utilizes a two-piece die-cut frame with integral pleat spacers on the air-leaving side. Pleat spacing is controlled by straps bonded to the air-entering side, and the multiple rows of pleat spacers on the air-leaving side. The pleat spacers also ensure that the pleats remain open during use, maximizing filter life.
DuraFlex® Media – Patented Media Design
Uniform size virgin fibers are assembled in closely controlled blends to create a media that is both self-supporting and consistent in performance. When pleated, DuraFlex media will hold its shape without the wire support characteristic of conventional pleated filters. That means no potential for the formation of rust, and safer handling. With the superior resiliency of DuraFlex media and no need for wire support, PerfectPleat SC M8 filters can sustain significant abuse and maintain their shape and pleat spacing. The absence of wire also makes the filter totally incinerable, which can simplify disposal.
