Features and Benefits

nnnn

■ Fast cycling with positive cutoff - provides precise

nnnn

operation with minimal dripping and spitting.

nnnn

■ Rugged, production-proven construction - minimizes

nnnn

downtime and maintenance costs.

nnnn

■ Several models available - dual-chamber guns can be

excellent finish quality with minimal overspray. Air-actuated ATA

nnnn

guns provide fast response time (30 to 40 milliseconds) and high-

nnnn

speed cycling capability (up to 2500 cycles per minute), and are

nnnn

ideal for coating situations requiring precise material application.
