| 20150316274 | Dehumidifier Air Filter System - A dehumidifier air filter system has: a dehumidifier module; a scrubber module; a dehumidifier adapter connected to the dehumidifier module; an air duct connecting the dehumidifier module to the scrubber module, and an air control window formed on the dehumidifier adapter. The air duct connects to the dehumidifier module at the dehumidifier adapter. The dehumidifier air filter system may be constructed with a front shell forming a housing for the dehumidifier apparatus within the dehumidifier module. The front shell has a front shell aperture. The front shell aperture receives the dehumidifier adapter, and the dehumidifier adapter is formed as a plate having at least two openings including: an air control window opening, and a ducting hose connector opening. | 11-05-2015 |
| 20150369182 | INLINE DUMP-ABLE FUEL SYSTEM DUST FILTER WITH PRESSURE RELIEF VALVE - A number of variations may include a product comprising a dump-able filter comprising: a filter body; a filter assembly, wherein the filter assembly is seated in the filter body; and a filter cap, wherein the filter cap attaches to the filter body and encloses at least a portion of the filter assembly. In some embodiments the filter assembly may include a filter carrier that includes a pressure relief valve. | 12-24-2015 |
| 055310000 | Pressure relief means to or from atmosphere | 1 |
| 20160023153 | MULTI-STAGE FILTER WITH PRESSURE RELIEF APPARATUS - A filter apparatus, a pressure relief apparatus methods are provided. The filter apparatus includes a tubular hull having an inlet port and an outlet port. A tubesheet partition separates the tubular hull interior into a first stage portion and a second stage portion. A plurality of filter elements are mounted in annular guides. A pressure relief apparatus is configured to relieve pressure through at least one of the annular guides with the pressure relief apparatus in parallel fluid circuit with the filter elements. The pressure relief apparatus includes an elongated tube, a sealing plug, an end cap, a rod disposed within the elongated tube with one end of the rod coupled to the sealing plug and another end of the rod coupled to the end cap; and a spring disposed in the elongated tube between the sealing plug and the end cap. | 01-28-2016 |
| 055312000 | Valved bypass means | 6 |
| 20100257824 | Filter Device, Particularly Reflux Vacuum Filter, and Filter Element For Such A Filter Device - The invention relates to a filter device, in particular a reflux vacuum filter, having at least one filter housing ( | 10-14-2010 |

| 20110030322 | SUPPLEMENTAL FILTER MEDIA SUPPORT INSERT FOR AN AIR CLEANER - A supplemental filter media support insert is provided for use with a filter element to reinforce the filter media against filter media deformation resulting from fluid flow induced forces. The support insert is configured for installation into an air cleaner near the filter outlet face and includes support ribs which may be generally aligned to overlay reinforcement bands provided on filter media. | 02-10-2011 |
| 20110113737 | Combination Relief Valve and Drainage Mechanism Requiring Inserted Element to Permit Drainage in a Coalescer System - Disclosed are coalescer systems for coalescing a liquid phase dispersed in a gas phase. The disclosed systems include a filter element which, when installed in the system, contacts and moves a valve to an open drainage position to permit flow of liquid through the system. In the disclosed systems, the filter element and valve also are configured such that under excess pressure conditions the valve permits the gas phase to bypass filter media of the filter element. In particular, the disclosed coalescer systems may be utilized in a CV system in order to remove oil mist from gas in the CV system. | 05-19-2011 |
| 20140290193 | FILTER MEMBER - A filter member is movable between a first position and a second position when passage of air through the filter member is obstructed. | 10-02-2014 |
| 055314000 | Shunt means for total flow | 1 |
| 20140366494 | Filter with a replaceable filter insert - A fluid filter with a housing, a releasable cover, and a replaceable filter having a filter body and two end discs. The filter is plugged onto a housing pipe and a locking ring is guided on the pipe, preloaded in a push-out direction. The locking ring is locked in a pushed-out position by a locking device. An unlocking device guided by the filter unlocks the locking device when the filter is pushed onto the pipe and enables the locking ring and the filter to be pushed in. When the filter is fitted into the housing, a seal on the end disc or locking ring interacts with a housing sealing surface to separate an untreated filter side from a clean side. When the locking ring is in the pushed-out position and the filter bears against the locking ring, the seal is held away from the sealing surface of the housing. | 12-18-2014 |
