The Aerostar Series 400 pleated air filter utilizes a state-of-the-art 100% synthetic media to achieve exceptionally high levels of efficiency with the lowest resistance to air flow available. The media is laminated to an expanded metal grid on the air exiting side to provide exceptional strength during installation. The media support grid prevents fluttering and maintains pleat uniformity for optimum performance. The filter pack is enclosed in a heavy-duty, moisture resistant die-cut frame that will not warp, crack, or distort under normal operating conditions.
