The pump pumps the exhaust to the environment from the coating chamber through the exhaust processor. | 06-18-2009 |
| 20090301308 | Filter Arrangement for Fuel Cell - A filter arrangement for cleaning fuel cell supply air, including at least two filter layers, whereby a first filter layer is designed as a coarse filter and a second filter layer as a fine filter, wherein the second filter layer includes an electret filter material. | 12-10-2009 |
| 20130340621 | COALESCING FILTER DEVICE FOR COLLECTING MIST AND EXTRACTING PARTICLES - A coalescing filter device that extracts harmful particles and mist from the air. The coalescing filter device may include a housing with a coalescing filter suspended within the housing. The coalescing filter may be suspended at an angle relative to the housing, such as a 45 degree angle. A blower may be attached to the top of the housing and may blow air from the inside of the housing to the outside. A bag filter may be sealed to the top of the coalescing filter and a charcoal filter may be secured to the housing in between the blower and the bag filter. | 12-26-2013 |
| 20140137742 | Air Cleaning Unit and Storage System Using the Same - The present invention provides an air cleaning unit which contains a blower, an acid/alkaline filter device, and a particle filter device. The blower draws in outside air through the acid/alkaline filter device and produces an air flow through the particle filter device. The acid/alkaline filter device absorbs the acid/alkaline gases in the outside air. The particle filter device traps the particles in the air flow. Through this design, the blower draws in air filtered by the acid/alkaline filter device. The blower therefore does not suffer erosion and therefore the air cleaning unit enjoys prolonged operation life span. | 05-22-2014 |
| 20140165842 | Fluid Filtration Device and System - A medical fluid filter system is provided comprising a housing having: a liquid trap chamber having a volume; a filter media chamber; a filter media arranged within the filter media chamber; the liquid trap chamber having a liquid trap outlet port in fluid communication with the filter media chamber; the liquid trap outlet port configured and arranged within the liquid trap chamber to inhibit flow of liquid from the liquid trap chamber to the filter media chamber and configured and arranged to allow gas to flow from the liquid trap chamber to the filter media chamber; a filter system inlet passing through the housing for intake of fluid originating from a surgical site; and a filter system outlet passing through the housing for fluid exhaust. | 06-19-2014 |
| 20140238243 | APPARATUS FOR FILTERING AIR - An air filtering apparatus includes a housing defining a top opening and having a front portion defining a bottom opening. A filter is positioned within the top opening and sealed to the housing so that air flowing into the housing passes through the filter. An expansion chamber is in fluid communication with the bottom opening. A motorized fan is located within the housing and is configured for drawing air through the filter, into the housing and out through the expansion chamber. The air output of the motorized fan is directed toward a bottom of the housing proximate a rear of the housing with the expansion chamber extending from the air output of the motorized fan to the front portion of the housing. | 08-28-2014 |
