Frequently Asked Questions
It’s a complete sprayer. It doesn’t install into another unit. The “Compatible & Related Models” list shows platforms that share accessories/components (hoses, guns, tips) within the DutyMax HD family.
Use professional airless hoses rated to at least 3300 psi (or higher). 3/8 in main line with a whip hose at the gun is common for heavy materials. Keep total length and pressure drop in mind for thick coatings.
Yes. The 3-in-1 convertible design allows swapping to an electric motor kit for indoor/low-emission work while maintaining pressure and pattern control.
Maximum single-gun tip size is typically up to 0.053 in, but always match tip to material, temperature, hose length, and desired production rate. Start with manufacturer-recommended sizes and adjust based on pattern and pump load.
