  • Page 32: Equipment Description

    1264 is used with plasma and High Velocity Oxygen Fuel (HVOF) thermal spray systems. The Model 1264 operates on a volumetric feed principle, where slots in a powder wheel at the base of the canister fill with powder. As the powder wheel rotates past the exit port, the powder is metered into the powder hose and carried to the spray gun in the gas stream.

  • Page 33: Options

    When the canister is in HVOF Pressurization Mode, the pressure relief valve remains closed and the canister remains pressurized until operator turns off power to canister. See Section 4 for a description of Model 1264 modes. A large numeric display shows current and pertinent canister conditions.
