PMC PX-7 Mechanical Purge Spray Gun Features

  • Mechanical Purge: There�s no need for solvent flushing or air purge due to a valving rod that mechanically purges material from the mixing module for optimal self-cleaning.
  • One-Piece Valving Rod: The one-piece valving rod is hand honed to integrate with the mixing module to extend the life of the module.
  • Internal Impingement: Designed to last, the mixing module has a variety of styles that can be used with different pattern control discs for high-level mixing and pattern development.
  • Steel Construction: Both the machined coupling block and gun block are created with high-strength stainless steel. Cracking is a thing of the past!
  • Rebuildable Manual Valves: The PX-7 includes sturdy, simple and affordable manual valves to rebuild easily.
  • Check Valves: Check valves on the PX-7 mechanical spray gun are easy to remove from side screen screws, making cleaning and maintenance a breeze.
