Spin-On Filter Heads
Aviation Aquacon® Spin-On Filters - Data Sheet #1769

AC-405SP is the popular 3.75” diameter x 5.5” long size. The AC-409SP is 3.75” diameter x 8.5” long. Five mounting head styles are offered for use with these two cartridges. Refer to the back side of this sheet for details.
Aquacon® Cartridges filter out water by chemically locking it into layers of super-absorbent media. Water removal efficiency is not affected by surfactants or additives, and once captured, the water cannot be squeezed out. These cartridges also effectively filter out dirt, rust, and other particulates.
As a cartridge reaches its water-holding limit, the media expands very rapidly and restricts the flow. For fuels, the flow may completely stop. For oils and other high viscosity liquids, the pressure drop will rapidly increase, signaling the need to change cartridges.
