Wiwa Gun 500F PFP

On the WIWA Gun 500F PFP, PFP stands for Passive Fire Protection - the gun is specifically designed to handle the high-viscosity fireproofing materials used in these applications, providing the pressure, durability, and performance required for professional PFP projects.

Passive fire protection coatings - often called intumescent coatings - are specialized materials applied to structural steel and other building components to help maintain their integrity during a fire. These coatings expand when exposed to heat, creating an insulating char layer that helps protect the substrate and delay structural failure.

Yes, the WIWA Gun 500F PFP is suitable for waterborne paints and coatings, thanks to its stainless-steel fluid passages and material-contact components, which resist corrosion and prevent contamination when spraying water-based products.

This makes the gun compatible with many waterborne industrial coatings in addition to passive fire protection (PFP) materials. The 500F PFP is a robust high-pressure airless spray gun designed for demanding coating applications, offering durability, ease of use, and reliable performance across both fireproofing and compatible waterborne products. Always check with the material supplier to confirm compatibility.

Both guns offer similar durability and performance, but the 500F PFP is optimized for intumescent and passive fire protection coatings, while the standard 500F is intended for general industrial coating applications.

The WIWA Gun 500F PFP and the standard WIWA 500F share the same core design, including a robust airless spray gun construction, stainless-steel fluid passages, a four-finger trigger, and a maximum working pressure of 500 bar (7,250 psi). The key difference is that the 500F PFP is specifically configured for Passive Fire Protection (PFP) applications, such as spraying intumescent fireproofing coatings, and is supplied with a 7/8" UNS tip housing thread to accommodate the larger spray tips often required for high-build fire protection materials. The standard 500F is a more general-purpose industrial airless spray gun designed for a broad range of protective coatings, corrosion-control coatings, and waterborne paints.

The wetted parts of the WIWA 500F are made of stainless steel to provide superior resistance to corrosion, wear, and chemical attack when spraying a wide range of industrial coatings.

Since these components come into direct contact with the coating material, stainless steel helps prevent contamination, extends service life, and improves compatibility with demanding products such as waterborne paints, corrosion-control coatings, and passive fire protection (PFP) materials. It also makes cleaning easier and helps maintain consistent spray performance over time, particularly in harsh industrial environments where durability and reliability are critical. WIWA specifically notes that the stainless-steel material passages make the 500F particularly suitable for waterborne coatings.

Yes. The WIWA Gun 500F PFP is compatible with hot spray circulation systems and is specifically recommended for applications where maintaining a consistent material temperature is important.

WIWA notes that the 500F can be used with its hot spray circulation system and return manifold to help keep coatings at a constant temperature during spraying. This is particularly beneficial when applying high-build materials such as intumescent fireproofing coatings, where proper temperature control can improve material flow, atomization, and overall finish quality. The gun's stainless-steel wetted parts and robust high-pressure design make it well suited for demanding heated coating applications.

The WIWA 500F PFP is specifically designed for demanding Passive Fire Protection (PFP) and industrial coating applications, primarily the application of intumescent fireproofing coatings on structural steel, storage facilities, industrial infrastructure, and commercial buildings to help maintain structural integrity during a fire.

The gun's high-pressure airless design and compatibility with large spray tips make it well suited for spraying the thick, high-build coatings commonly used in passive fire protection systems. In addition to fireproofing applications, the WIWA 500F PFP can also be used for a variety of industrial protective coatings, including corrosion-control coatings and compatible waterborne products. Its stainless-steel wetted parts, high operating pressure, and compatibility with hot spray circulation systems make it a versatile solution for contractors working in the fireproofing, industrial maintenance, marine, petrochemical, and structural steel industries.
