water separation

Whether a filter also drops free water out of the fluid, and whether that water can be drained off at service or leaves with the discarded body. Declared at `Filter` and not on any child, because the fact is not fuel's alone: Hy-Pro publishes its water-removal elements — G8 Dualglass media behind a water-removal scrim, in spin-on and cartridge styles — for hydraulic, lubrication AND fuel systems alike. Diesel is where it matters most, since diesel always carries water and water destroys a high-pressure injection pump, but a lubrication or hydraulic circuit takes in water too. Unstated for intake air and cabin air, which have no water phase to separate.

Water separation is answered with one word chosen from the water separation types list — the same word shared across every product that uses it.
