Abstract
Abstract An in-line trap (10) for removing water and/or oil vapor from a compressed airline which includes a manifold (12) having spaced coaxial inlet and outlet openings (20, 30) and a hollow base (32) suspended from the manifold. A first cartridge (54) extends between the manifold inlet and the enclosed volume (37) within the hollow base, and includes a wire fiber pad (62) adapted to coalesce water and/or oil vapor in air passing therethrough into droplets which are then entrained by the air and carried into the base volume. Within the base, a plate (48) having parallel louvers or vanes (52) upwardly struck therefrom in a direction opposted to air travel is supported with respect to the base bottom wall by a honeycomb spacer (44) which forms a dead air space beneath the louver plate. The louvers function to trap vapor droplets which fall by gravity from the air entering the base volume. A second cartridge (56), which includes spirally wound fiber (92) and wire (94) mesh materials, directs compressed air from within the base volume to the manifold outlet and simultaneously functions to remove any remaining vapor therefrom.
