$20.29Graco 17N387 Cover Filter Turbine Std Series delivers a robust first-line barrier for airless turbine motors, ensuring uninterrupted operation and painting precision. Precision-engineered for compatibility with standard turbine-driven spray systems, this cover filter integrates seamlessly into maintenance regimens, extending equipment longevity while preserving paint quality. Advanced mesh architecture traps debris at high flow rates, reducing downtime and costly repairs. Expert installers appreciate its straightforward mounting procedure and user-friendly orientation marks. When reliability is paramount, 17N387 stands out as a go-to choice for professionals demanding peak productivity under rigorous conditions.
Compatibility with numerous commercial-grade units lets operators integrate this filter cover into existing systems, especially those built around versatile pump paint sprayer platforms. Precision tolerances ensure leak-free seals, while quick-release clamps simplify part swaps during shutdown cycles. By maintaining consistent flow profiles, this cover filter helps sustain the sprayer’s output quality throughout extended tasks. Contractors valuing uninterrupted workflow can count on its maintenance-friendly design to minimize interruptions and protect internal turbine components from abrasive particulate contamination.
Optimized filter media captures particles down to sub-micron levels without impeding airflow, preserving turbine efficiency. Computational fluid dynamics (CFD) data guided the design of internal flow channels, reducing turbulence-related pressure drops. This ensures a steady supply of clean air to the turbine blades, preventing abrasive wear and maintaining rotational balance over time. When spray viscosity or environmental dust levels vary, this adaptive filtration system consistently delivers uniform suction performance, safeguarding coating consistency across large-scale architectural or industrial projects.
Versatility extends beyond primary filtration. As part of a portfolio of graco airless sprayer accessories, users can fine-tune turbulence and pressure dynamics via optional pre-filters or post-filter expansions. This modularity supports application-specific requirements, whether applying heavy-bodied coatings or thin primers. Cover geometry optimizes airflow to maintain consistent atomization at various PSI settings. Installation within existing manifolds demands minimal reconfiguration, allowing technicians to deploy or swap the assembly with ease during routine maintenance or process adjustments.
Routine upkeep is streamlined thanks to a snap-fit design and clear flow-direction arrows molded into the housing. When servicing intervals arrive, operators can replace filter elements without disassembling downstream components or disconnecting hoses. Integration with common graco paint gun accessories—including quick-connect fittings and adaptor kits—ensures compatibility with diverse spray guns and fluid circuits. This smart configuration minimizes tool requirements and training overhead, letting teams focus on coating operations rather than complex part changes.
Exposure to solvent-laden atmospheres and abrasive particulates can accelerate wear on lesser filter covers. Manufactured from engineered thermoplastic composites reinforced with fiber additives, the 17N387 housing resists chemical attack and mechanical shock. UV-stabilized compounds protect against sunlight degradation on outdoor projects, while sealed gaskets prevent moisture ingress during high-humidity applications. This rugged construction supports continuous operation in harsh jobsite conditions, reducing unplanned stops and ensuring consistent surface finish quality.
To maximize service life, replace filter cartridges on a regular schedule aligned with coating viscosity changes and environmental dust loads. Periodic inspection of clamp hardware and sealing surfaces prevents the risk of leaks, which can introduce contaminants into the turbine chamber. When integrated into a comprehensive preventive maintenance program—complete with documented filter logs and torque calibration—this cover filter becomes a central component in achieving repeatable, high-quality spray results for large-scale commercial projects.
For those seeking additional support, Graco offers dedicated filter replacement kits and on-site maintenance training tailored to the 17N387 model. These professional maintenance services ensure optimal filter performance and compliance with industry standards.
Whether upgrading an existing turbine system or specifying a new airless spray line, 17N387 provides the filtration integrity and mechanical resilience required by serious coating professionals. Rely on this turbine cover filter to maintain peak equipment uptime, enhance finish consistency, and streamline service workflows.
