$5.67Introducing the Spacer Back 4 Stage Turbine, model 17N376, by Graco, engineered to elevate air delivery in demanding finishing environments. Designed around a four-impeller system, this turbine achieves stable output pressures while maintaining smooth, pulsation-free airflow. Its spacer-back geometry improves cooling and reduces vibration, ensuring prolonged motor life. Precision manufacturing tolerances deliver consistent performance even under extended operation, making it ideal for commercial painters, industrial coating specialists, and rental fleets seeking reliable, high-volume output. Integration with existing sprayer units is straightforward, reducing setup time and optimizing workflow efficiency for both new builds and refurbishment projects.
Robust housing components use high-grade polymer composites reinforced with glass fibers to withstand harsh solvent exposure and occasional accidental drops. Bearings are heavy-duty and sealed against contamination, minimizing downtime caused by particulate intrusion. Internal heat channels guide airflow across the motor windings, preserving insulation integrity and preventing thermal overload. Integration with a magnum airless paint sprayer setup is seamless thanks to standard 1/4-inch NPT ports and universal mounting brackets that adapt to a wide range of pump frames without modification.
Each of the four turbine stages is dynamically balanced at the factory to limit radial runout below 5 micrometers, dramatically reducing audible noise and mechanical wear. Aerodynamic impellers employ backward-curved blades, optimizing static pressure generation while controlling tip speed for quieter operation. A precision-engineered diffuser cage further converts velocity into usable pressure, pushing coating material through longer hose runs without compromising spray quality. Consistent volumetric flow supports delicate finishes such as automotive clear coats or architectural lacquers, delivering uniform atomization across the full spray gun fan width.
Routine inspection is simplified by a modular front end plate that provides quick access to impellers and bearings without disturbing electrical connections. An optional service kit bundles replacement seals, mounting grommets, and graco quickshot parts recommended by factory-trained technicians. Scheduled bearing lubrication intervals, based on operational hours, help prevent premature failures. For workshops offering on-site adjustments, calibrated tachometer ports allow real-time RPM verification, ensuring turbines remain within specified operating windows.
Model 17N376 mates with a broad range of sprayer pumps and pressure control units. Upgrade paths include an advanced noise-reduction shroud or a low-EMI version for sensitive electronics rooms. Power connections support both 120 V and 240 V supplies with simple jumper-bar adjustments, so international deployment requires minimal effort. Custom voltage configurations and exterior color options are available through authorized service centers, helping branding-conscious contractors maintain a consistent fleet appearance.
Technical support remains a cornerstone of the ownership experience, with certified technicians offering guidance on fluid compatibility, turbine reconstruction, and electronics calibration. Replacement schedules, based on service hours, guarantee uninterrupted project timelines, aided by genuine graco replacement pump assemblies sourced directly from factory distribution channels. This comprehensive approach ensures that performance benchmarks are met from initial startup through thousands of operating cycles.
