Sturdy Construction and Dependability
The VariCel RF filter, 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 efficiency and dust holding capacity are maximized.
Supported Pleat Media Pack
The 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 the entire length of each side, provide maximum sealing. Competitive filters are designed with loose fitting headers that allow greater potential for bypass leakage.
Layered Synthetic Media Pack
The layered media used in the VariCel RF filter 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, and is non-shedding and water-resistant.
Open Header Design
AAF Flanders’ unique open header design creates a built-in handle that makes carrying and installing the VariCel RF filter easy. As an added safety measure, we roll the edges of the header to eliminate sharp edges that can make handling competitors’ products hazardous.
