High Efficiency PTFE Filters • Lower energy consumption — greater than 40% lower resistance • AAF Helior PTFE media combines ultra-high efficiency with lowest pressure drop • Highly resistant to corrosive environments (acids, alkalis, and organic substances) • Negligible off-gassing properties (boron, sodium, potassium, silicon) • High tensile strength media, more resistant to rough handling in transportation and installation • Withstands pressure up to 20 in. w.g. (5,000 Pa) • 99.99% minimum efficiency @ 0.3 µm MEGAcel I HEPA filters are designed to meet the demanding airflow and efficiency requirements of critical applications in which airborne contaminants must be carefully controlled. Manufactured with high-performance Helior media and unique tapered aluminum separators, MEGAcel I filters optimize efficiency while keeping operating costs to a minimum. State-of-the-Art Design Designed to combine maximum efficiency with lowest pressure drop, the MEGAcel I filter media pack is available in different depth, size, and cell-side configurations, allowing for a variety of application requirements including: Healthcare Perfect Filter Media Compared with micro-fiberglass media, Helior media provides superior benefits including inert chemical properties, more uniform fiber distribution, smaller fiber diameters, and smaller pore size. As a result, reduced resistance and higher filtration performance provide substantial energy savings. PTFE pleat pack resistance is a minimum of 40% lower than conventional micro-fiberglass media, a significant factor contributing to greatly reducing fan energy consumption. AAF Helior media combined with tapered aluminum separators optimizes pleat pack resistance. With a reduction in fan energy consumption, overall energy savings can be realized. Food Processing Energy Conservation = Energy Savings Developed by AAF Engineers: Helior ® PTFE Media Groundbreaking Helior PTFE media technology was engineered by AAF's research and design teams. Media production, testing, and packaging are all performed in AAF's (ISO 7) ultra-modern controlled environment, eliminating the potential for contamination of the filter during manufacturing. Photographed at 10,000x magnification, these images illustrate the finer fiber diameter and more consistent composition of Helior media (Figure A), when compared with micro-fiberglass media (Figure B). ®
