Hvof Gun

Fuel and oxygen combine and atomize within the combustion area under conditions that monitor the correct combustion mode and pressure required for coating.

Hvof gun. The unique design of this gun allows it to produce particle velocities of 3 300 to 3 900 fps which is significantly higher than any other gaseous fueled hvof device on the market today. Tafa model 5220 hp hvof gun the tafa model 5220 is a kerosene fueled hp hvof gun that is used to achieve extremely high coating densities. Combustion gases such as hydrogen and liquid fuel such as kerosene are used. We offer both gas fueled and liquid fueled options.

Wokastar series liquid fuel spray guns. Hvof gun is a thermal spray system utilizing the combustion of gases or liquid. Hvof guns for thermal spray the need for tougher more wear and corrosion resistant surfaces is served by our high velocity oxygen fuel hvof spray guns. The compressed air cools the chamber when entering the gun.

The mixture of compressed air oxygen in hvof system mode and the fuel gas flows into the combustion chamber through the orifices of a catalytic ceramic insert. The resulting hvof process creates high particle velocities and dense low oxide coatings.
