Latest Patents
One of Ager's latest patents is the Shift Pleat Air Filter. This panel-type filter employs a rectangular filter element with shifted pleats, where the peaks of the pleats on the upstream and downstream sides alternate between high and low peaks. This configuration decreases turbulence at the upstream side of the filter, which reduces restriction. The reduced restriction increases air flow to the engine, resulting in lower fuel consumption and higher engine output power. Additionally, compression and turbulence are minimized at the downstream side, leading to a more laminar flow past sensors, thus enhancing their effectiveness.
Another significant patent is for Air Filter Elements with Foam Pre-Cleaners. These filter elements feature primary filter media with foam pre-cleaners that have an increased surface area defined by an upstream face with peaks and valleys. In one embodiment, the peaks and valleys are created by parallel ribs. If the filter element is a panel-type with pleated primary filter media, the pre-cleaner is secured to the primary filter media by adhesive deposits on the peaks. For annular filter elements, the pre-cleaner is slid axially over a perforated sleeve or screen and held by friction. This design significantly improves the capacity, efficiency, and lifespan of the filter element.
