Catalog excerpts

The production-proven Nordson RA-20 rotary atomizer delivers painting efficiency and superior finishing quality and operating safety for a wide range of finishing applications. Unlike conventional painting bells, the patented RA-20 has no minimum sparking distance. As a result, it can be positioned close to parts for optimal coverage and minimal overspray. In addition, the fine atomization and soft spray apply thin, controllable film builds with minimal paint bounceback. The RA-20 delivers superior finish quality in a safer, more productive and cost-efficient painting operation. The RA-20 rotary atomizer’s superior performance and reliability are due to a combination of advanced features. These include RA-20 Rotary Atomizer Close-in painting capability with optimal coverage, greater operating flexibility and improved paint savings in a wide range of finishing applications. Features and Benefits Close-in painting for high transfer efficiency and superior penetration into part recesses. Outstanding atomization delivers fine finishers and precise film-build control. Excellent pattern control reduces overspray significantly for reduced paint waste. Applies a variety of coatings including solvent-based, high-solids, waterbornes, waterborne emulsions, two-component materials, metallics and 100-percent-solids coatings. Wide pattern adjustability - from 8 to 42 inches. Compact size for easier positioning within spray booth. Long-life, air-bearing turbine. Durable composite cup. Safe, non-sparking operation. Choice of manual or automatic controllers. Special design helps prevent backflow into turbine at high flow rates and during flushing operation. vector air for superior pattern shaping, long-life air-bearing turbine design, innovative electrostatic charging system and a proprietary composite cup. Close-in painting for superior performance. The close-in painting capability of the RA-20 delivers superior penetration into part contours and recesses. The RA-20 provides stronger electrostatic attraction for more complete parts coverage and reduced touch-up requirements for unmatched finish quality. And overspray is reduced substantially for significant paint savings

RA-20 Rotary Atomizer Excellent spray-pattern control. The RA-20 rotary atomizer uses vector air to control pattern shaping, rather than by shaping air from the cup. Elimination of shaping-air holes that can plug with paint reduces rejects, and speeds maintenance and cleaning. In addition, different cup sizes can be easily changed to meet spray pattern requirements. With the RA-20, spray patterns can be adjusted from eight to 42 inches wide, depending on the coating material used. This allows for application of a precise amount of paint with minimal overspray with less paint waste and lower...

RA-20 Rotary Atomizer Patented atomizing cup design for operating versatility. Patented Nordson RA-20 atomizing cups are available in several sizes and styles to optimize atomizer performance based on coating type, part profile and finish requirements. The composite construction of the RA-20 cup contributes to the non-sparking design, and is actually more durable than conventional metal cups. The RA-20 atomizing cup will not chip, crack or lose its shape under normal use. Three edge styles are available to deliver performance benefits for specific types of coatings: Finned cup – delivers...
