The challenge was to comply with
air regulations in the State of Texas in a non-attainment area. In order to
comply, an Alternate Reasonably Available Control Technology (ARACT) was
This committed Bell Helicopter Textron, Inc. (BHTI) to using High Volume Low Pressure (HVLP) paint guns. Additionally, paint improvements were completed in 1995 when Bell changed from high solvent paint to a high solid formula that required less solvent.
As a result of the paint gun installation and the new high solids paint, Bell reduced paint consumption by 15%. The cost of implementation is far outweighed by the compliance factor and reduced paint usage, thus air emissions.
Another waste reduction effort was to install plural component paint mixing systems. This system is used with multi-part paint. The objective is to mix the paint to the proper consistency just prior to spraying. After the paint gun is used, the nozzle is purged with solvent to clean the gun before the paint dries. This system has helped BHTI to reduce solvent usage and paint waste. Less material usage and lower waste disposal cost are the savings realized.
