Poker vibrators
High-frequency poker vibrator with integrated inverter and PRCD.
The HS-ER is designed around ease of use and operator safety for flooring professionals. Its integrated 230V inverter does away with a separate converter — it plugs into any wall socket — while a built-in PRCD guards against electrical danger. The vibration-damping handle removes around 90% of the vibration reaching the body and leaves room for a gloved hand. It shares the LHF and HS build quality and long life, and its plug-and-go simplicity makes it well suited to hire.
No separate converter needed — the inverter is built in.

The 'ER' in HS-ER refers to its built-in electronic converter, which automatically regulates the 230V mains supply into the 42V/200Hz high-frequency power the poker head needs — no separate converter box to carry, tune or protect from wet concrete. A PRCD residual-current device and a vibration-damping handle, which removes around 90% of the vibration reaching the body, round out the safety and comfort side.
The HS-ER ships complete with a 0.85 m hose and a 20 m special wear-resistant cable with built-in PRCD protection, in bottle diameters from Ø36 to Ø65 mm. Custom lengths are available on request.
