AAF’s high velocity weather louver removes moisture and fine mist, the first stage to any filter system.

The presence of water and salt can cause irreversible harm to pre, fine and (H)EPA filter medias. Free moisture allowed to interact with pre and fine filters coalesces on media fibers, mixing with captured dirt particles which absorb the moisture, swell and increase pressure drop.

Water accelerates dirt- and salt-laden water leaching which carries over to foul the engine compressor.
