Paint Overspray Collection Systems Air Technologies Inc. Ottawa, Kan.

Air Technologies Inc. (ATI) announces that its OSM- 100 and Aerospace 3000 Paint Overspray Collection Systems exceed the EPA Aerospace NESHAP Final Rule for paint overspray collection of inorganic HAPS for aerospace manufacturing and rework facilities. Each system was tested using Test Method #319, which is the only test method recognized by the EPA to determine if an overspray collection system meets the efficiency guidelines. Existing paint booths and new paint booths have different requirements.

Ion Exchange Membranes Koch Membrane Systems Inc. Wilmington, Mass.

Koch Membrane's K-Cel l offers signif icant advan- tages to any existing or new line for electrocoat paint applications. K-Cell electrodes are seamless, tubular, ion-exchange membranes specifically designed to con- trol paint chemistry by selectively removing disassoci- ated paint solubilizers from electrocoat tanks. Longer electrode life, more current capacity per cell, and no paint fouling configuration result in significant savings compared to other electrode configurations.
