The PORPHIS VS (Variable Split Nozzle) Spray Gun is engineered for professionals who demand consistent, high-transfer atomization across large surface areas. The split nozzle design breaks paint into a finer, more uniform mist without requiring excessive air pressure, reducing overspray and material waste on every pass. Requiring 15.2 CFM at 29 PSI, VS guns are built for serious bodywork, full-panel refinishing, and industrial coating where finish quality is non-negotiable.

A:The PRD-817 features anaviation-grade forged aluminum body, with all fluid passages, nozzles, and needles crafted from304 stainless steelto eliminate rust at the source. Before assembly, every unit undergoestriple ultrasonic vacuum cleaningand an internal anti-corrosion coating process. We guarantee that your air cap pores and fluid passages are free of any machining debris.Ready to spray out of the box—no clogs, no rust.
A:Unlike other brands that tap threads directly into soft aluminum, the PRD-817 uses embedded stainless steel thread inserts at both the cup and air inlet. This prevents stripping even with frequent cleaning or over-tightening. Additionally, it comes standard with a 300° swiveling limited joint, reducing lateral torque from the air hose and further protecting the threads.
A:The PRD-817 utilizesVS Split Nozzle Technology. The fan control knob provides a clear"Click" mechanical feedbackwith every turn. The pattern width changes linearly—no more "dead zones" where half a turn does nothing, followed by a sudden jump. Paired with our precision needle valve, you get consistent tactile feedback from a fine detail line to full-width coverage.
A:"Spitting" is usually caused by poor sealing or pressure fluctuations. The PRD-817’s needle and nozzle arefactory-matched and hand-lapped, featuring adual-layer conical seal. This ensures a continuous, uniform spray even when using low-viscosity waterborne clears or heavily thinned coatings. Furthermore, theself-cleaning air capactively prevents residue buildup, eliminating clogs that cause spitting.
A:The PRD-817 requires 15.2 CFM (430 L/min), which is the standard for professional-grade performance. For optimal results, we recommend a 3HP+ compressor with a 60-gallon tank. If you are using a small home setup, we highly recommend our PRD-510 LVLP series(only 5.6 CFM). For pros seeking the ultimate atomization, the PRD-817 is designed to unleash its full potential with a full-size air system.
A:Absolutely. The PRD-817’s VS Split Nozzle and Self-Cleaning Air Cap are optimized specifically for waterborne coatings. It produces ultra-fine droplets that are "Long but Full"—ensuring a wet edge without the "dry spray" or "orange peel" common with waterborne clears. Paired with a 1.3mm nozzle, you can achieve a show-car-level mirror finish.
A:The PRD-817 is our flagship model, offering lower overspray (1% vs average), higher pattern uniformity (+30%), a self-cleaning air cap, military-grade coating, and a 300° swivel joint. The PRD-717 is our classic split-nozzle workhorse—highly reliable and perfect for most professional repairs at a competitive price. Choose the PRD-817 for maximum efficiency and mirror-like finishes; choose the PRD-717 for proven reliability on a budget.
A: The PRD-817 is designed to go head-to-head with Tier-1 international brands in atomization quality, coating durability, and overspray control, but at a more accessible price point. Our unique advantages—such as the Self-Cleaning Air Cap, 300° Swivel Joint, and extended consumable life—are features many competitors lack. We back this up with a 1-year warranty and full spare parts availability for total peace of mind.
