• Redesigned for improved performance and durability.
• Layered synthetic media with plastic pleat spacers on both sides.
• Heavy-duty expanded metal media support grid.
• Ideal for VAV systems.

The RigiFil II has been redesigned for improved strength and durability, and is ideal for Variable Air Volume (VAV) systems. It provides
a high level of filtration efficiency in those applications where cleaner air is required. With metal cell sides and a layered synthetic media
pack, the RigiFil II offers superior dust holding, moisture resistance, and overall performance. Color-coded media designates each
efficiency: 90-95% (Yellow), 80-85% (Pink), 60-65% (Green), and 45-50% (White). Both single and double-header models are
available.

The RigiFil II, with its galvanized steel cell sides 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
that both the efficiency and dust-holding capacity are maximized.

RigiFil II's 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 the entire length of each side, provide maximum sealing.
Competitive filters are designed with loose fitting headers that allow greater potential for bypass leakage.

AAF's unique open-header design creates a built-in handle that makes carrying and installing RigiFil II 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 II 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.
