Dura-Metal has designed, manufactured and commissioned many thermal spray systems internationally. With over 50 years of combined experience and a product range that covers virtually all thermal spray processes, we can offer you the highest quality equipment to support your application needs.
High Velocity Air Fuel (HVAF) torch system has revolutionized thermal spraying with a new level of coating quality. Compared to commercially available High Velocity Oxygen Fuel (HVOF) systems, the HVAF process offers significant advantages in two areas. First, the use of air for combustion in the AF 6000 HVAF System offers tremendous savings over the cost of oxygen in HVOF systems. Second, the HVAF torch is regeneratively cooled by the same air it burns, so it does not require water cooling as the HVOF system does. This eliminates the problems and expense of the cooling water and associated systems.
AF 6000 Thermal Spray System consists of the Model AF-6000 torch, Model AF-6000C Control Console, the Model DM 1200HP-PF Powder Feeder, and the cable and hose set.
AF 6000 Thermal Spray System uses up to 5 GPH (19 LPH) of kerosene, (A-1). This fuel is inexpensive, safe, easily stored, and readily available around the world. The system uses 140 SCFM (3948 SLM) of compressed air which cools the torch and supports combustion. The air requirement can be met using a standard 50 HP shop air compressor. If this is unavailable, Dura-Metal offers both motor and diesel-driven compressors.

For more than 20 years, Dura-Metal has been working in the field of HVOF coating to restore worn out parts and also with OEM to develop wear resistance coating applications.
We are pleased to introduce the Durajet HV 3000 HVOF system. It’s economical, robust, lightweight, and of excellent quality. Durajet HV 3000 powder thermal spray system melts metallizing powder by heat generated through the combustion of fuel gas and oxygen. The metallizing powder is fed at a regulated speed to a flame-spraying torch that may be hand-held or motion-controlled. A continuous flow of compressed air surrounds the flame, atomizes the molten metal, and disperses it over the surface of the object to be coated. The spraying torch may be guided by hand for spraying large or intricate pieces; for production work, the torch may be mounted to programmable equipment, such as an x-y manipulator or a robotic arm. The HV 3000 system also comes with an optional add on, water cooled jacket (HV-JET HYBRID ASSEMBLY). This module will increase the torch thermal efficiency and also powder depositing efficiency – resulting in high-density coatings. This low capital HVOF equipment is an ideal system for small and medium size jobs shops.
We also offer model HV 3000-A auto-start HVOF system. It is PLC control with I/O signals or commands for turnkey integration.
