Abstract: The separator is of a type comprising at least one inclined deflecting surface mounted within a fluid flowing path so that water droplets contained in the flow of fluid are separated from the fluid when the fluid is deflected by the deflecting surface. The deflecting surfaces comprise collecting recesses for water that has been separated, which recesses are connected to an under-pressure space in which is maintained an under-pressure with respect to the pressure prevailing in the fluid flowing path.

Abstract: In an oil reservoir tank having a tank body and a tank cover, an air/oil separator includes a filter media pack, arranged radially symmetrically about an axis, a bottom end cap secured to one end of the filter media pack, and a top end cap and flange member.

Abstract: Apparatus and methods for separating fluids of differing specific gravities are discussed. More specifically, apparatus and methods for separating a high volume flow mixture of air and water into an essentially dry air component and a pure water component are discussed. The separator is high volume and is structured around three physical elements which are defined as an input, a water chamber and an air separator chamber. A composite flow enters the input where most of the heavier water component separates, under the force of gravity, and flows into the water chamber. The remaining fluid, which is air and water in the form of vapor, mist, or droplets, is drawn into the air separator chamber using a vacuum pump, and subsequently flows through a condensate sub chamber which physically is an element of the air separator chamber. Any moisture in this flow is condensed within, and drained from, the condensate chamber such that dry air is discharged from the air separator chamber.

Abstract: A mechanical fluid separator defines an interior chamber for centrifugally separating entrained media from a fluid stream. The mechanical fluid separator has a fluid inlet connecting the interior chamber with a media entrained fluid source. A cone shaped baffle disposed within the mechanical fluid separator defines a conical surface having a concave surface and a convex surface. The conical surface has an annular base side and an annular apex side. The base side terminates in a circumferential rim contacting the annular chamber surface above the fluid inlet and said apex side terminates in an apex annular hole. The fluid stream is centrifugally directed in a first direction about the annular chamber surface and the convex surface of the conical baffle to disentrain the entrained media from the fluid stream. The disentrained fluid stream then passes through a window in the cone shaped baffle and escapes through a fluid outlet.
