The Multiquip EM511021 Air Ducting Clamp is a genuine OEM component designed for hydraulic-driven concrete pumps in the LS series, including the LS400, LS500, LS40D, LS40TD, LS50TD, and LS600. As a direct OEM replacement, this clamp is manufactured to the exact specifications required to secure air ducting within these machines, ensuring proper airflow routing and a tight, leak-free connection. Sourced directly through Multiquip's authorized parts channel, the EM511021 delivers the fit and function your pump depends on. DHS Equipment stocks genuine Multiquip parts to help keep your concrete pump running without guesswork.
Key Features
- Genuine OEM Retention Strength — Manufactured to Multiquip's exact clamping specification, ensuring the ducting stays secured under operational vibration and pressure cycles typical of concrete pump environments.
- Direct Drop-In Replacement — Engineered to match the original mounting points and duct diameter on LS series concrete pumps, allowing straightforward installation without modification.
- Broad LS Series Compatibility — Confirmed fitment across LS400, LS500, LS40D, LS40TD, LS50TD, and LS600 hydraulic-driven concrete pump models.
- Maintains Proper Airflow Routing — A correctly functioning air ducting clamp keeps cooling and intake air directed where the engine and hydraulic system need it, preventing heat-related performance issues.
- Fuel and Thermal System Safety — Properly secured air ducting prevents hot air recirculation and reduces the risk of heat buildup near fuel and hydraulic components, making this a safety-relevant service item on concrete pump equipment.
The air ducting clamp secures flexible or rigid air ducting within the machine's engine and ventilation system, keeping airflow directed along the correct path for cooling and combustion intake. On concrete pumps like the LS series, where hydraulic and engine components generate significant heat during extended operation, a failed or loose clamp can allow hot air to recirculate or ducting to collapse, leading to overheating, reduced engine efficiency, and potential damage to surrounding components. Replacing a worn or damaged clamp promptly with the correct OEM part, such as the EM511021, restores the integrity of the airflow system and protects the broader drivetrain.
