Standard Features*

  • Solvent Free >>> The Gusmer Air Purge  Gun, as with all Gusmer guns, features a mechanically self-cleaning valving rod assembly that purges all mixed material from the mixing areas at the end of each shot, eliminating costly and environmentally harmful, solvent flushing procedures.
  • Ergonomic Design  >>> 33% lighter than other air purge guns, its compact size and ergonomic handle combine to give the gun superior balance and feel for unparalleled maneuverability, reduced operator fatigue and improved directional control of spray.
  • Trigger Action >>> The air purge system in the GAP Gun is accurately rated to operate at 125 psi. This produces more responsive trigger action while keeping the mixing chamber cleaner, longer.
  • Screens >>> Less clogging, a more uniform pattern. The GAP Gun is the only air purge gun to have screens on each side of the gun to have screens on each side of the gun to filter out impurities in iso and resin lines that lead to clogging and pattern deformation.
  • Mixing Chamber >>> Longer lasting - with a standard mixing chamber fabricated from high strength hardened alloy steel and coated with the proprietary Gusmer Gold Teflon, the GAP Gun promises durability and optimal mixing at all times.
  • Variable Spray Pattern  >>> A variety of outputs and patterns. Interchangeable mixing chambers and spray tips provide virtually every output and flat or round pattern you'll ever need.
