A Powder inlet from powder container

D Dosage air inlet
S Powder/air mixture outlet to gun
The switched air mode:
No powder is fed to A if the feed air F is
switched off and, simultaneously, the
dosage air quantity D is increased to
maximum level.
No new powder A is fed to the spray
gun, while the powder feed hose S is
regularly purged with dosage air. The
powder flow A starts immediately as
soon as the feed air is switched on
again and the dosage air is switched to
normal quantity.
The powder injector is used for powder feeding in manual as well as automatic powder coating
systems. In addition to this, the powder injector is also ideally suitable for switching mode.
All types of coating powder can be processed with the injector.
A choice of two powder injectors is available:
• powder injector PI-P1 and
• powder injector PI-F1
The PI-P1 powder injector is connected to control units, which regulate air pressure.
The PI-F1 powder injector, on the other hand, is connected to control units which control the
compressed air flow rate, making this powder injector suitable for applications involving control
units with AFC technology (flow rate control) and purging air mode for powder flow.
Both powder injectors can be operated with the following control units:
• powder injector PI-P1 with EPG 2008/EPG Prima or PrimaTech
• powder injector PI-F1 with EPG-D1 or ProfiTech
Caution
The maximum temperature should not exceed 35 °C / 95 °F. Otherwise it cannot be
ensured that the powder output quantity of the HiCoat-ED Pump can be reached.
