highest quality air filtration solutions

PerfectPleat ? HC M8 - MERV 8 PerfectPleat ? - MERV 7 1" and 2" Extended Surface, Pleated Filters with Process-Controlled Quality 2 The Air Filtration Leader AAF International, one of the world’s largest manufacturers of air filtration products, is known for technical innovation and excellence. Designed, developed, and patented by AAF, the PerfectPleat filter is a product with form and fit unlike any other pleated filter in the marketplace today. In addition, the PerfectPleat filter has the efficiency you need and expect. Superior Design and Construction Drawing on years of experience in manufacturing quality air filters, AAF has created a state-of-the-art process for producing pleated filters. The extremely high quality of these filters is a result of three unique innovations: a new, automated manufacturing process; a unique, self-supporting media; and a filter construction that provides incredible strength without wire support. Since their introduction, pleated filters have become a larger and more important segment of the filtration marketplace. However, conventional design and process are not conducive to the manufacture of consistently pleated media packs or finished filters. Inconsistency in pleat arrangement, variations in media, improper bonding of media to frame, along with antiquated manufacturing techniques, have a negative impact on efficiency, resistance, durability, and strength. The automated and controlled process AAF has developed for the PerfectPleat filter eliminates these inconsistencies and irregularities. Our automated manufacturing process offers consistency unmatched by conventionally manufactured pleats.

Filter — Heavy Duty Frame The perimeter frame of the PerfectPleat HC M8 and PerfectPleat filters is constructed from the highest wet-strength 28 pt. beverage carrier board available, securely bonded to the media pack. The 28 pt. thickness improves filter strength and helps resist damage. Uniquely designed pleat stabilizers are bonded to the media on the air leaving side to ensure uniform pleat spacing and provide additional strength. On the air-entering side, support straps increase the rigidity of the PerfectPleat filter. The support straps and pleat stabilizers ensure integrity against turbulent airflow and provide excellent lateral stability for installation in side-access systems. based on 2" PerfectPleat ? HC M8 filter Filtration Efficiency (%) Particle Diameter (micrometers) Increasing Efficiency — Throughout Life of the Filter Particle Size Efficiency Curves The PerfectPleat filter is designed to consistently increase its efficiency throughout the service life of the filter. Competitive pleated panel filters, manufactured using an electret charge to obtain the MERV 8 rating, perform with declining efficiency over time. PerfectPleat HC M8 and PerfectPleat filters have initial MERV 8 and MERV 7 ratings respectively, but the efficiency increases significantly when dust loading begins. Applications PerfectPleat filters have distinctive self-supporting characteristics that allow a pleating pattern, which promotes airflow and maximizes dust holding capacity (DHC). The PerfectPleat HC M8 filter is ideal for applications where pleated filters are currently in use and higher efficiencies are required or desired. The PerfectPleat filter is best suited for standard capacity pleated filter applications. Heavy Duty (HD) PerfectPleat filter is available for applications where extremely low temperature and high airflow are present. See Brochure AFP-1-201. Every PerfectPleat filter offers superior durability and performance when properly installed and maintained. Environmentally Responsible Air Filtration Solutions AAF is committed to operating with a goal of sustainability. We have implemented several initiatives to work and manufacture in an environmentally responsible manner and contribute more to protecting our planet by using fewer natural resources and reducing our carbon footprint. The PerfectPleat filter product design minimizes base raw material consumption and meets our “Green” product development standards. The PerfectPleat filter product line is totally incinerable and the absence of support wire simplifies disposal. Used during construction, PerfectPleat HC M8 filters may contribute to LEED? certification points under IEQ categories. 1" PerfectPleat ? Filter — Strength and Durability The 1" PerfectPleat HC M8 and PerfectPleat filters have the same durability and performance as the 2" models. Both are made using DuraFlex media encased in a 28 pt. beverage carrier board frame. PerfectPleat 1" filter models feature a perimeter frame, with three supporting straps on the air entering and air leaving sides of the filter. Both models resist crushing and abuse and can be used in any application where 1" filters are currently in place. The PerfectPleat HC M8 and PerfectPleat filters rate MERV 8 and MERV 7 respectively.

DESCRIPTION: Mini-pleated V-Bank filters use glass fire media with efficiencies in H10, H11, H13 and H14. The frames can be galvanized steel or aluminium SPECIFICATIONS: Series: V-Bank Series Frame: ABS Separators: Hot Melt Media: Glass Fibre Sealant: Polyurethane Temperature: <70oC Humidity: <100% RH Efficiency: H10 (EN1822) > 95% MPPS: >95% (H11); DOP: >95% @ 0.3μm MPPS: >99.95% (H13); DOP: >99.97% @ 0.3μm MPPS: >99.995% (H14); DOP: >99.99% @ 0.3μm Recommended final Pressure Drop: < 600Pa ADVANTAGE: Extended media surface filters create lower resistance to higher air flows which saves energy consumption. Large media area, up to 41 M2 provides filters with longer life and higher dust holding capacity. This is a perfect choice for your most critical environments. APPLICATIONS: These filters are suitable for almost any allocation, such as pre filter for power generating facilities, or final filter for high-tech industries. These filters can function normally in areas of repeated turbulent air flow, repeated fan shutdown, desert, and marine installations.

Pneumafil’s STMP line of high efficiency static barrier air filters is specifically designed for gas turbine inlet air systems. Using an all synthetic medium and an all plastic frame, the STMP product offers a wide range of filtering efficiencies, high volumetric airflow, low pressure drop, and high dust holding capacity. At the heart of the STMP is an all synthetic medium with fibers made from an electret spinning process which imparts a deeply imbedded electrostatic charge. The charge ensures peak particle collection efficiency from the first day of service. The fibers are thermally bonded so the medium is non shedding and has a higher mechanical strength than the glass medium. There are no mechanical fasteners of any type used in the assembly. The frame is all plastic so that the entire filter is incinerable or shreddable when it is time for disposal. The assembly is extremely rugged and resists handling and installation damage. The pleated media packs are offset* from the air entering face to provide better air distribution and lower pressure drop when prefilters are mounted directly in front of the Synthetic TMP.

DuraVee? HXL High Capacity, High Efficiency Barrier Filter for Rotating Machinery ? High efficiency and dust holding capacity ? Extended media area ? Water resistant media ? Sturdy construction ? Full polymer construction ? Fully incinerable ? Free of halogens DuraVee? HXL is a heavy duty, high efficiency filter developed specially for the Gas Turbines industry. It is designed to withstand the rigours of centrifugal compressors, gas turbines and engines where surging or pulsation occur.The DuraVee HXL dust holding capacity is higher than comparable 12 inch deep filters, providing longer periods between replacement. Media DuraVee? HXL media is water resistant and can withstand exposure to free moisture in the airstream. When wet there will be a temporary rise in resistance, which quickly returns to normal as soon as the moisture evaporates. The design ensures a full depth loading of dirt across the entire surface of the filter. Construction The header and cell sides provide a sturdy construction that resist damage during shipping and handling. Rigid construction and minimum depth make DuraVee? filters easy to install in front, rear and side access systems. Separators The hot melt separators maintain uniform spacing between pleats to allow optimal flow of air into and through the filter. They also ensure large effective media area for low resistance and high dust holding capacity. Better Air is Our Business ? Operating Temperature DuraVee? HXL filters can operate at temperatures up to 70°C (158 F). The filter is fully incinerable. Rear view filter detail. DuraVee?
