Painter Review
BEST Porphis gun ever made? New tip design for optimized clear coat atomization. PRD 817
Porphis PRD817 Spray Gun, Low Pressure, Low Overspray, Low Air Consumption V Tip PRD815
Say goodbye to orange peel and cloud patterns
— Achieve a flawless mirror finish in one go.
After all the hard work of spraying, do you still end up with an uneven finish that requires tedious sanding, polishing, or even rework? The PRD-817 features a fully optimized atomization pattern that improves coating uniformity by 30%. From the first coat of primer to the final layer of clear coat, it delivers a smooth, level finish as flawless as a mirror. It not only saves you hours of sanding but also ensures every project you deliver has a truly professional-grade surface quality.
The iconic orange finish is not just about looks
— It’s built to withstand years of wear and tear.
The appearance of a tool that is frequently used in harsh environments is a direct reflection of its durability. The military‑grade plasma electrolytic coating on the PRD-817 is no ordinary paint. Its multi‑layer protective shield resists solvent corrosion, scratches from hard objects, and daily abrasion. Years down the road, that signature orange finish will still look as vibrant as the day you first held it.
Critical parts last longer
— Let time become the witness of quality.
The air cap and nozzle are the heart of a spray gun’s atomization performance, yet they are also the most vulnerable wear parts that need frequent replacement. Through a structural breakthrough in the “dynamic tolerance zone,” the PRD-817 extends the service life of these key components by 30% compared to other spray guns. This not only reduces the hassle of finding and replacing parts but also significantly lowers long‑term maintenance costs.
Low to the ground? Tight angles?
It moves more nimbly than your hand.
When you need to get the spray gun extremely low to paint car rocker panels or furniture bottoms, ordinary swivel joints tangle the hose and make operation painfully difficult. The PRD-817’s 300° limited‑swivel connector was born to solve exactly this problem. Its compact design and extra‑wide rotation angle allow the hose to follow your movements freely, without ever tangling. You can easily lower the gun even further and handle complex angles with ease — your work is no longer limited by the hose.

FAQs - PRD-817
Q1: Many other brands have metal shavings or rust inside their guns. How does the PRD-817 ensure cleanliness and corrosion resistance?
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.
Q2: Are the threads prone to stripping? How durable are the cup and air line connections?
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.
Q3: Why do some other spray guns have unresponsive fan control knobs? Is the PRD-817's adjustment linear?
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.
Q4: Does the PRD-817 suffer from "spitting," especially with thinned clear coats?
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.
Q5: Can my small home compressor (2-6 gallon / 8-24L) run the PRD-817?
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.
Q6: Is the PRD-817 suitable for waterborne clear coats? Will the atomization be sufficient?
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.
Q7: What is the difference between the PRD-817 and PRD-717? Which should I choose?
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.
Q8: How does the PRD-817 compare to brands like Iwata or SATA?
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.

the gun works realy good.

This is the best fun I’ve used so far. I spray a hybrid clear coat that I developed for restoring oxidized RVs so consistency is key for me for those big vertical walls. If anything goes wrong while spraying such as dry spots or heavy top and bottom patterns I have to respray the entire wall, with this gun I haven’t had that problem at all.

Seller stated the item with a value on the cn22 form resulting in a sales tax and administration fee for me. The website clearly stated that sales tax was included, annoying and not the first time this happened. Item is original and arrived in new condition.
