The Shape of the Future Key to the performance advantage in Ultipleat SRT filters is the wave-shaped pleat geometry. Wave-shaped pleating: • Allows more filtration area to be packed into a given filter element envelope • Creates uniform flow distribution through the filter element • Protects against pleat collapse and bunching Mathematically Optimized Filter Area Figure 1 represents the geometric model used to determine the optimal pleat shape to maximize filtration area. Pall has determined that a geometric “involute” shape, more simply described as a wave shape, yields maximum pleat area. This...

The Ultimate in Filter Design Pleat Stability Figure 4 represents a poorly supported fan-pleat filter Pleat Grouping element subjected to high differential pressure or “cold start” flow conditions. The pleats tend to be unstable and can move, thus increasing pressure on the flanks of the pleats. The result can be pleat collapse and the “bunching” together of pleats, which reduces useable filtration area and filter service life. In contrast, the pleats in Ultipleat SRT filter elements touch and support each other (see figure 3) and are held in place via the helical wrap on the outside of the Area...

Reporting Filter Performance Ultipleat SRT Filter Performance Rated as an ISO 4406 Cleanliness Code Ratings Problem Filter A ISO 4406 Cleanliness Code 20/17/13 • ISO 16889 (Beta ratings) are derived under steady state conditions. • Real world conditions including cyclic variations in flow, pressure and dirt loading can affect filters, leading to a decline in Beta value with increasing element pressure drop. Particle Count Summary Size >4 µm(c) Ratings Solution • Pall's Cyclic Stabilization Test (CST), based on SAE ARP 4205, applies cyclic flow (25 to 100% of rated flow) and contaminant loading...
