The PerfectPleat HD M8 filter is built to withstand more difficult applications, extremely low temperature, and higher airflow. Using AAF’s patented PerfectPleat filter as a base, our engineers developed the PerfectPleat HD M8 filter by incorporating maximum structural reinforcement into the PerfectPleat filter’s already extremely durable construction. At the heart of the PerfectPleat HD M8 filter is AAF’s patented, self supporting DuraFlex media. We retained the support straps and pleat stabilizer assembly characteristic of the innovative PerfectPleat filter media pack. We added a die-cut frame for additional strength and acrylic glue to bond the media pack to the cell sides and give the PerfectPleat HD M8 filter a broader operating temperature range.
