Mechanical Purge: PX-7 incorporates a valving rod to mechanically purge the mixed material from the mixing module at the end of each shot; eliminates the need for solvent flushing or air purge.
Hand Honed One-Piece Valving Rod: In addition to tight tolerance manufacturing of the one-piece valving rod, the PMC PX-7 valving rod is then hand honed in the areas that mate with the mixing module, thus improving the life of the module.
Internal Impingement: Mixing module is designed for long service life. A large variety of styles are available to be used in conjunction with various pattern control discs to provide the highest level of mixing and pattern development.
Machined Coupling Block: PX-7 comes standard with a precision machined coupling block made from high strength steel.
Rebuildable Manual Valves: PMC has included the latest innovation in rebuildable manual valves on the PX-7 guns that are sturdy, simple and economical to rebuild.
Stainless Steel Hardened Gun Block: No more worries about cracking a cast gun block. The PX-7 gun block is made from Stainless Steel and is then hardened for long life, minimum wear and provides a positive and robust connection for the coupling block screw.
Check Valves: Easy removal of check valves from Side Screen Screws for maintenance and cleaning.
How the Mixing Chamber Diferrers from Other Models:
There are two basic types of spray guns: Air Purge and Mechanical purge. Air purged spray guns are popular among spray foam contractors for interior and exterior spray foam insulation applications. Air purged spray guns (shown in photo) work by a piston attached to a mixing chamber. Air is used to actuate the piston and purge the mixing chamber. In the non-triggered position, air is constant. When triggered, the air supply, traveling through the mixing chamber, is halted and replaced with the A and B chemicals. The material is then mixed and dispensed. The spray foam insulation material is manufactured through the spray gun. When the trigger is released the material supply is halted and replaced with air, purging the mixing chamber. While the basic principles of the spray guns are the same, the designs differ.
Mechanical purge spray guns are popular among spray foam contractors for interior and exterior spray foam insulation. Mechanical purge spray guns (shown in photo) work by a piston attached to a valving rod. Air is used to actuate the piston moving the valving rod through a mixing chamber. In the non-triggered position, the valving rod halts the material flow. When triggered, the piston moves the valving rod and the material is mixed and dispensed. Spray foam insulation is manufactured through the spray gun. Using an air purge spray gun or a mechanical purge spray gun is a matter of preference. Each has its own merits. Consult with a distributor or a supplier for specific uses.
Press Release:
Over the past few years, many of our distributors and end users have requested that PMC provide a mechanical purge gun. We listened and are excited to announce that PMC unveiled our new PX-7 Mechanical Purge Gun at the Spray Foam Show in Palm Springs California this past week.
Our product brochure, for the new PX-7 gun, highlights some of the benefits and features over current mechanical purge guns on the market. The PX-7 will be available initially as a POUR GUN designed primarily for concrete slab jacking and will be available for shipments starting on April 1, 2017.
The second model that will be available will be a SPRAY GUN, designed for high output foam and coatings i.e. residential foam, roofing, pipelines and containment. This spray model will be available shortly after the pour gun is released.
The third version will be a low output spray gun designed primarily for spraying low output polyurea.
The PX-7 Gun Package will be offered at a very competitive price and spare parts will be very reasonably priced as compared to our competition.
PMC thanks for your continued support.
