20090020486 | Filter assembly and method - A filter assembly comprising a filter head having inlet and outlet ports; a filter bowl attached to the filter head, wherein the filter bowl has a drain hole located at the bottom of the filter bowl for draining fluids; a filter element housed within the filter bowl, the filter element including a barrier of filtration media, a drain layer and at least one support tube; wherein a pressure differential exists across the filter element; a bottom cap that seals fluid within the filter element; a top cap having a non-planar flange portion, wherein the flange portion has a substantially curving, generally s-shaped cross-sectional profile, the non-planar flange sealingly received within the filter head such that the filter head is divided into inlet and outlet partitions; wherein the top cap directs fluid from the inlet port into the filter element, where the fluid flows through the barrier of filtration media and then out of the assembly through the outlet port; and, a float drain component attached to the base of the filter bowl and aligned with the drain hole for controlling a condensed fluid level within the assembly. | 01-22-2009 |
20100043637 | Filter Assembly and Method - A filter assembly having a filter head having inlet and outlet ports and a top cap having a substantially curved, non-planar flange portion, the non-planar flange sealingly received within the filter head such that the filter head is divided into inlet and outlet partitions. In some embodiments, the flange portion has a generally s-shaped cross-sectional profile. The flange portion incorporating a modified venturi for improved flow of both inlet and outlet streams through the filter assembly. | 02-25-2010 |
20120174599 | THERMOELECTRIC COMPRESSED AIR AND/OR INERT GAS DRYER - A gas dryer is provided. The gas dryer includes a first opening structure forming a cooling pathway fluidly connected to the first opening; a first thermoelectric device thermally connected to the structure forming the cooling pathway and a heat exchanger. A condensate drain is located near an end of the cooling pathway and configured to drain condensate formed when a fluid is cooled along the cooling pathway. A structure forming a warming pathway is located between the condensate drain and a second opening, and a second thermoelectric device thermally connected between the structure forming cooling pathway and the structure forming the warming pathway and connected to exchange heat between the cooling pathway and the warming pathway. A method of drying a gas is provided. The method includes directing the gas through a cooling pathway, removing heat from the gas in the cooling pathway with a first thermoelectric device to a heat exchanger, condensing a fluid out of the gas. The method further includes draining the condensed fluid from the gas, directing the gas though a warming pathway and removing heat from gas in the cooling pathway with a second thermoelectric device and inserting that heat into gas in the warming pathway. | 07-12-2012 |
20160038862 | Multi-Cartridge Filter Adapter and Interface System and Method - An attaching system for a filter cartridge may include: a top cap configured to attach to a filter cartridge; a mating projection located on the top cap; at least one locking projection projecting radially away from the mating projection; and a base portion defining an annularly shaped flat surface surrounding the mating projection on a first side and configured to attach to the filter cartridge on a second side. A method of attaching a filter cartridge to a filter assembly may include: providing locking projections on a top cap of a filter cartridge; locating a spring around a mating projection of the top cap; forming annular groove between the spring and the locking projections; and configuring the top cap to a portion of the filter cartridge. | 02-11-2016 |
