  • Page 14: Guarantee

    SAMES KREMLIN atomizer PPH 308 is covered by a one-year guarantee for use in two 8-hour shifts under normal operating conditions. By concession, the guarantee is extended to 10000 hours on the air turbine of the PPH 308. The guarantee does not apply to wearing parts such as atomizing bellcups, diaphragms, clips, seals, etc.

  • Page 15: Description

    Atomizer PPH 308 is used in automatic mode for electrostatic atomization of solvent-based liquid paints. The PPH 308 is a complete atomizer with built-in painting and rinsing assemblies for single or dual circuits. It is fitted with a magnetic air bearing turbine, operating under an air cushion, capable of reaching a rotation speed of 45000 rpm.

  • Page 17: Magnetic Air Bearing Turbine Type "Btm

    2.5. Magnetic air bearing turbine type ”BTM” see RT Nr 6350 This turbine has no mechanical shaft; it is centered by the polarity difference between the bear- ing magnets making it totally frictionless. The bearing air evenly spread over the stator surface produces an air cushion that pushes the rotor away from the stator.

  • Page 18: Turbine Rotation Speed

    2.5.1. Turbine Rotation Speed An acoustic method is used to measure rotation speed. The air arrives at the injector holder. The channel machined in the ’microphone reader” located on the bellcup allows air to pass each time the bell cup rotates This pressure variation induces a noise, or "frequency signal"...
