Part 975-300 is a 2-gun add-on kit designed for compatible PowrTwin airless sprayers. It contains all necessary components to operate two spray guns simultaneously from one pump, allowing two operators to work at once. This kit maximizes productivity on large-scale projects when original systems need multi-gun capability.

The 975-300 2-gun add-on kit is a comprehensive accessory package engineered to enable compatible PowrTwin airless sprayers to operate two spray guns simultaneously from a single pump. This capability transforms a standard single-operator sprayer into a high-production system capable of doubling application rates on large-scale commercial, industrial, and multi-unit residential projects. The kit includes all hydraulic and mechanical components necessary to tap into the pump's fluid output and provide two independent, fully functional outlets. Typical contents include a precision-machined manifold block, pressure-adjusting valves for each outlet, check valves to prevent backflow, mounting hardware, and all required fittings and connectors.
Successful dual-gun operation requires careful system engineering to ensure both operators receive adequate flow and pressure regardless of individual trigger demands. The 975-300 kit addresses this with integrated pressure compensation and independent adjustment for each outlet. This allows operators using different hose lengths, tip sizes, or spraying techniques to optimize their respective pressure settings without affecting the other. The kit's check valves ensure that triggering one gun does not cause pressure drop at the other, and permit safe tip changes or gun maintenance while the second operator continues working. All components are constructed from materials compatible with the full range of professional coatings and cleaning solvents, and are rated for the high operating pressures typical of airless spraying.
Installing the 975-300 kit significantly enhances productivity on suitable projects. The installation process typically involves mounting the manifold assembly at a convenient, accessible location on the sprayer cart, connecting it to the pump outlet, and attaching the two gun hoses to the manifold outlets. Each operator then has independent control over their spray gun, with the pump responding to both triggers. It is essential to verify that the specific PowrTwin model has adequate flow capacity for two-gun operation; using the kit on an undersized pump will result in inadequate performance for both operators. The kit includes detailed, illustrated instructions and all necessary hardware for a professional installation. For contractors with high-volume applications, the investment in a 975-300 kit delivers rapid return through reduced labor hours, faster project completion, and improved equipment utilization.
