Wiwa Gun 500F With Swivel, 4-Finger

The WIWA Gun 500F with Swivel, 4-Finger is a professional high-pressure airless spray gun designed for applying a wide range of industrial coatings, including protective coatings, corrosion-control coatings, primers, waterborne paints, and other heavy-duty coating materials. Its robust construction and maximum operating pressure of 500 bar (7,250 psi) make it suitable for demanding industrial, marine, manufacturing, and structural steel applications. The integrated swivel connection helps prevent hose twisting and improves operator comfort, while the four-finger trigger provides better control during extended spraying sessions.

The 500F is particularly valued for its stainless-steel material passages, which offer excellent durability and compatibility with waterborne coatings and other chemically demanding materials. It can also be used with WIWA hot spray circulation systems to help maintain consistent material temperatures when processing specialized coatings. Overall, the WIWA 500F with Swivel is a versatile airless spray gun built for contractors and industrial painters who require reliable performance in challenging coating applications.

The primary difference is intended application: the WIWA 500F PFP is specifically configured for Passive Fire Protection (PFP) coatings, such as intumescent fireproofing materials, and uses a 7/8" UNS tip housing thread commonly required for the larger spray tips used with high-build fireproofing coatings. The standard WIWA 500F is a more versatile industrial spray gun designed for a broad range of coatings, including corrosion protection coatings, primers, and waterborne paints.

Both guns are built on the same high-pressure airless spray gun platform and share many features, including a 500 bar (7,250 psi) pressure rating, stainless-steel wetted parts, a four-finger trigger, and an optimized swivel connection that reduces hose twisting and operator fatigue.

In short, if your primary application is intumescent fireproofing or passive fire protection, the 500F PFP is the preferred choice. For general industrial coating work, the standard 500F offers the same durability and performance while supporting a wider range of coating applications.

The swivel joint on the WIWA 500F is designed to improve operator comfort and make spraying easier by allowing the spray hose to rotate freely as the gun is moved. This helps prevent hose twisting, kinking, and resistance during operation, reducing fatigue during long spraying sessions and improving overall handling.

WIWA also notes that the optimized swivel design contributes to a lighter-feeling gun and makes it easier to maneuver when applying coatings in challenging positions or confined spaces. For contractors applying industrial coatings, corrosion protection systems, or fireproofing materials, the swivel joint can improve productivity by allowing smoother gun movement and reducing strain caused by heavy high-pressure hoses - resulting in better control, greater comfort, and a more efficient spraying experience, especially on larger projects where the gun may be used continuously for extended periods.

Yes. The WIWA Gun 500F is specifically designed to be compatible with waterborne coatings. WIWA states that all material-contact (wetted) parts of the 500F are made from stainless steel, which provides excellent resistance to corrosion and makes the gun well suited for spraying water-based paints and coatings.

This construction helps prevent material contamination, improves durability, and allows the gun to handle both traditional solvent-based coatings and modern waterborne coating systems. In addition to waterborne paints, the WIWA 500F is commonly used for a wide range of industrial coating applications, including protective coatings, corrosion-control coatings, primers, and specialty finishes. Its high-pressure airless design, durable construction, and swivel connection make it a versatile choice for professional contractors and industrial painters who require reliable performance across multiple coating types.
