RigiFil is a rigid, durable extended surface filter that is ideal for Variable Air Volume (VAV) systems. It provides a high level of filtration in those applications where cleaner air is required. With metal cell sides and a layered media pack, the RigiFil® offers superior dust holding, moisture resistance and overall performance. Color-coded media designates each efficiency : yellow (90-95%), pink (80-85%), green (60-65%), and white (45-50%). Both single header and double-header are available.

The RigiFil, with its galvanized steel enclosing frame and plastic pleat spacers on the air-entering and air-leaving sides, withstands the most demanding applications. The pleat spacers and expanded metal support grid maintain the shape of the synthetic media pack and ensure both efficiency and dust-holding capacity are maximized. The wire grid covers less than 2% of the media area such a manner that the surface filtration is promising.

RigiFil rigid construction with supported pleat media pack maintains a compact unitized structure under variable air velocities and repeated fan shutdowns. The interlocked header and cell sides, along with entire length of each side, provide maximum sealing. Competitive filters are designed with loose fitting headers that allow greater potential for bypass leakage.

For RigiFil single header model, AAF's unique open-header design creates a built-in handle that makes carrying and installing RigiFil easy. As an added safety measure, we roll the edges of the header to eliminate sharp edges that can make handling competitors' products hazardous.

The layered media used in the RigiFil is a meltblown synthetic protected by a scrim on the air-leaving side. Layering the media provides both a high-efficiency final filter layer that effectively filters fine particulate and an integral lofted prefilter layer that captures larger particulate. Meltblown synthetic media is stronger than fiberglass, non-shedding, and is water-resistant. The media pack is ultrasonic sew both edge and is bonded to the cell sides to ensure a leak-free seal.
