According to one embodiment of the invention, a system for mixing particles in fluid is provided. The system includes a container defining a chamber. The chamber has a narrowing region and is operable to be pressurized. The system also includes an agitator that has one or more flexible edges positioned in contact with the surface of the narrowing region. The agitator is operable to sweep the surface of narrowing region using the one or more flexible edges to agitate the particles. The system also includes an opening that is positioned at the narrowing region.

System for fluid agitation

An air pollution control apparatus usable for capturing airborne pollutants present in a relatively confined environment. The apparatus is a portable airborne-pollutant capturing device movable to a site of pollutant origin and having at least one airborne-pollutant collector member, a vacuum system, and a filter system. The filter system can include one filter or more than one identical or different filters chosen for enhanced filtration capabilities in relation to pollutants present. Preferably, more than one type of filter can be accommodated simultaneously to thereby capture multiple pollutants. Fugitive particulate is captured by positioning the airborne-pollutant collector member proximate the activity causing pollution, and operating the collector member simultaneously with the polluting activity to thereby cause particulate to be captured by the filter system.

Portable air pollution control apparatus

An air pollution control apparatus for capturing airborne pollutants present in a relatively confined environment. The apparatus includes a portable airborne-pollutant capturing device movable to a site of pollutant origin and having at least one airborne-pollutant collector member which can be non-limitedly exemplified as a collection hood positionable at the site of pollution for pollutant collection or a painting tray upon which items can be placed and painted and beneath which resultant pollutant can be collected. A vacuum system is present within the capturing device and is in communication with the one or more collector members to draw airborne pollutants into the capturing device through the pollutant collector member. Actual capture of pollutants is accomplished by a filter system within the capturing device. The filter system can include one filter or more than one identical or different filters chosen for enhanced filtration capabilities in relation to pollutants present. Preferably, more than one type of filter can be accommodated simultaneously to thereby capture multiple pollutants.

Portable air pollution capture apparatus with painting tray

In accordance with the present invention, there is provided a high volume, low pressure paint spray gun connectable to a paint source, an atomization air source and a shaping air source. The paint spray gun is provided with a spray gun body which is in fluid communication with the paint source, the atomization air source for atomizing paint and the shaping air source for shaping paint spray patterns. The spray gun is further provided with a nozzle which defines a paint atomizing zone for discharging atomized paint and a paint spray pattern shaping zone shaping atomized paint spray patterns. The spray gun is further provided with a paint hose, atomization air hose, and shaping air hose each having an inlet end which is connected to the spray gun body and a discharge end which is connected to the nozzle. The spray gun is further provided with a bendable, shape-retaining paint conduit having an inlet port which is connectable to the spray gun body and an outlet port which is connectable to the nozzle. The hoses extend through and are contained within the paint conduit. The paint conduit allows the nozzle to be self-supporting for maintaining the paint atomizing and shaping zones remote from and at any angle relative to the spray gun body for selectively discharging atomized paint and shaping resulting paint spray patterns thereof.

Micro spray gun

An apparatus for the cleaning of spray guns and components thereof, and more particularly, a preferably portable and compact apparatus including an enclosed cabinet structure for the contained cleaning of paint spray guns and various accessories thereof in order to minimize the emission of volatile organic compounds from cleaning solvents.
