High-Velocity Oxy Fuel (HVOF)

High-Velocity Oxy Fuel (HVOF)

Producing the highest-quality coatings

Nothing is more important in an HVOF system than its ability to produce high-quality coatings. Each of our systems is designed to generate extremely high particle velocity to produce ultra-dense coatings at exceptional rates. And we offer both liquid-fueled high-pressure and gaseous-fueled equipment developed to help you achieve the highest-performing coatings possible. See our HVOF coating equipment below.

TAFA Model 5220 HP/HVOF Gun -

Model 5220 HP/HVOF GunThe TAFA Model 5220 is a kerosene-fueled HP/HVOF gun that is used to achieve extremely high coating densities. 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.

Model 5220 features:

  • Efficient combustion and particle heating

  • Efficient gun cooling

  • Multiple gun configurations with multiple barrel lengths

  • Radial, low-pressure powder injection

  • Thick coating capability

TAFA Model 8200 HP/HVOF Gun -

Model 8200 HVOF GunThe TAFA Model 8200 is a kerosene-fueled HP/HVOF gun that is used to achieve extremely high coating densities. More efficient than the Model 5220 Standard Gun, it offers the same outstanding coating characteristics but at dramatic operating cost savings—increasing powder deposit efficiency and feed rate while reducing fuel and oxygen consumption.

Model 8200 features:

  • Efficient combustion and particle heating

  • Efficient gun cooling

  • High feed rates without loss of deposit efficiency

  • Lower operating costs

  • Radial, low-pressure powder injection

TAFA Model 825 JPid HP/HVOF Inside Diameter (ID) Gun -

Model 825 JPid HP/HVOF ID GunThe TAFA Model 825 JPid is a kerosene-fueled HP/HVOF gun that achieves quality carbide coatings on inside diameters as small as 8” /203 mm. The model is ideal for spraying HP/HVOF-quality coatings on cylinder bores, pump housings, tight confines of Francise turbine vanes and more.

Model 825 features:

  • Extension length up to 36” / 914 mm

  • High feed rates

  • Inside diameter coating capability

  • Low operating costs

  • Radial, low-pressure powder injection

TAFA Model 7700GF Gaseous-Fueled HVOF System -

Model 7700GFThe Mode l 7700GF system is a cost-effective, efficient and safe way to produce high-quality gaseous-fueled HVOF coatings.
