Multiquip EM231011 Air Vibrator

The Multiquip EM231011 Air Vibrator is a genuine OEM component designed for the C30HD series concrete pumps, including C30HD, C30HDG, C30HDZ, C30HDN, and C30HDNI variants. As a direct OEM replacement, this part meets the original design specifications set for Mayco concrete pump equipment in the Multiquip portfolio. Sourced directly through DHS Equipment, the EM231011 ensures you are receiving an authentic part with the correct fit for your specific machine. Verify your model code against the C30HD series before ordering to confirm compatibility.

Key Features

• Genuine OEM Construction: — Built to the original pneumatic output and vibration frequency specifications required for consistent hopper agitation on C30HD series concrete pumps.
• Direct-Fit Replacement: — Mounts to the existing air supply connections on compatible C30HD series machines without additional modification to fittings or brackets.
• Broad C30HD Series Coverage: — Confirmed fitment across C30HD, C30HDG, C30HDZ, C30HDN, C30HDNI, and C30HDNI Precision and Zenith engine configurations.
• Sustained Concrete Flow: — A properly functioning air vibrator keeps material moving through the hopper and prevents concrete from bridging or stalling during pump operation, maintaining consistent output.
• Authentic Multiquip Part: — The EM231011 part number is verified against Multiquip OEM documentation, so you can order with confidence that this is the correct replacement for your pump.

The air vibrator on a concrete pump is mounted to the hopper and uses compressed air to generate a rapid vibrating action against the hopper walls. This vibration keeps freshly mixed concrete agitated and flowing freely down toward the pump intake, preventing the material from clumping, segregating, or bridging across the opening. When the air vibrator fails or loses output, concrete can stall in the hopper, causing pump cavitation, uneven output, or a complete stoppage — all of which interrupt the pour and add time to the job.
