CE 0080 P/N: * ISSeP06ATEX032X** II 2 G EEx > 350mJ (Serial no.) * ATEX PPH 308 configurations P/N PPH GNM 200A P/N 1517071 910003721 ** 'X' indicates that the safety distance specified in this manual (between the HV components of the atomizer and all grounded parts) must be observed to ensure safe operation of the equipment. -
Page 7: Precautions Foruse
This document contains information that every operator must be familiar with and understand before using the PPH 308 atomizer. This information highlights situations that could result in seri- ous damage and indicates the precautions that should be taken to avoid them. - Page 8 The electrostatic spraying device must be regularly serviced in accordance with the indications and instructions given by SAMES KREMLIN. The equipment must be cleaned either in authorized areas equipped with a mechanical ventilation system, or using cleaning fluids with a flash point at least 5°C higher than the ambient temperature.
- Page 9 WARNING : The use of extra high voltage power increases the risk of sparks. SAMES KREMLIN atomizers and high-voltage electrostatic generators are designed to minimise this risk. Although the HV electrode is the only accessible part, a safety distance of X mm (see table below) must be maintained between the HV parts of the atomizer and all grounded parts.

Page 17: Description
The PPH 308 atomizer is used in automatic mode for the electrostatic spraying solvent liquid paints. The PPH 308 is a complete atomizer with built-in painting and rinsing assemblies. It is fitted with an air-cushioned magnetic air bearing turbine capable of reaching a rotation speed of 45,000 rpm. -

The injector holder is permanently secured to the body of the PPH 308. It is fitted with an injector whose restrictor can be changed according to the pressure drop required for the paint spraying equipment and product used. -
Page 19: Magnetic Bell Cup" Type Magnetic Air Bearing Turbine
2.4. “Magnetic bell cup” type magnetic air bearing turbine see RT Nr 6350 The bell cup is rotated by means of a pneumatic motor. Paint is sprayed due to the centrifugal forces generated by rotation of the bell cup. The higher the rotational speed, the smaller the particles that are sprayed. -

For values greater than 6 MΩ.cm, you are advised to use the PPH 308 with integrated high voltage unit. ** m values given for a temperature of 20 °C at 1013 mbar atmospheric pressure. -
Page 22: Operating Principle
3.3. Operating principle 3.3.1. Turbine see RT Nr 6350 This turbine has no mechanical shaft and is kept aligned simply by the polarity difference between the bearing magnets. This system also completely eliminates friction. The bearing air, which is uniformly distributed across the stator surface generates an air cushion, separating rotor and stator. -
Page 23: Turbine Rotation Speed
The microphone is linked to a SAMES KREMLIN frequency/voltage control to convert the analogue frequency signal into an analogue level signal (0 - 10 V) or digital signal (pulse).
