The AHFV22 equips concrete professionals with what product engineers note is a powerful, compact and efficient solution for better mix consolidation in most applications. Its Intelli-Vibe feature utilizes internal sensors to control vibration in response to concrete slump variations and rebar blockage. This ensures consistent high centrifugal force, stable speed and high amplitude for professionally finished concrete. A built-in frequency converter enables users to turn to a regular wall socket versus a generator or invertor. — Allen Engineering Corp., Paragould, Ark., 870/236-7751; www.alleneng.com
