Frequently Asked Questions
Yes. Performance specs are similar, but the 25U478 is cordless and uses DEWALT® 20V/60V MAX FLEXVOLT® batteries. Choose cordless when outlets are not convenient or mobility is critical.
Up to 0.019 in, provided your coating and application support it. Always match tip size to material viscosity and desired finish.
The sprayer is designed for DEWALT® 20V/60V MAX FLEXVOLT® packs. Higher-capacity FLEXVOLT® batteries typically provide longer runtime per charge.
Up to 150 ft of 1/4 in airless hose, within the unit’s pressure/flow capability and coating requirements.
High-build or very viscous coatings may exceed a 0.019 in tip or the sprayer’s flow capability. Check the coating manufacturer’s spray spec; you may need a larger-frame sprayer for heavy elastomerics.
Rinse/flush after each use, keep inlet strainers and filters clean, use storage fluid when idle, and leverage the ProXChange™ pump for quick swaps if wear occurs.
