Wacker Motor-in-Head Internal Concrete Vibrators

The micro-converter built into the on/off switch automatically converts the single-phase 60-cycle to a three-phase 180-cycle. This high-tech, solid-state electronic brain even senses "dirty power" (low voltage from a too-small extension cord, erratic voltage from a faulty generator, etc.) and shuts the vibrator down before it can become damaged.

The sealed switch housing encloses electronic components that are embedded in a special resin to ensure protection against moisture, impact and vibration.

Three IRFUN models are available with the converter system. The IRFUN 38 has a 1½-inch diameter head and an effective compaction diameter up to 20 inches. This unit can compact up to 34 cubic yards of concrete an hour. The midsize model, IRFUN 45, has a 1¾-inch diameter head and an effective compaction diameter up to 24 inches, which can compact up to 41 cubic yards of concrete an hour. The largest vibrator, IRFUN 57, has a 2¼-inch diameter head and an effective compaction diameter of 33 inches to compact up to 57 cubic yards per hour.

The IRFUN motor-in-head internal vibrators are built for reliability and require minimal maintenance. Disassembly and repair are fast because repair parts are designed as component groups. These vibrators feature Class H windings, the most heat resistance available, and motor protection if the vibrator is run outside of the concrete.
