Key Features
- Genuine OEM Construction — Manufactured to original Multiquip specifications, so ducting geometry, material grade, and connection points match the factory-installed component exactly.
- Correct Channel Routing — Designed to route and direct airflow through the engine and hydraulic cooling circuit without modification to mounts, clamps, or adjacent components.
- Broad LS-Series Compatibility — Fits LS400, LS500, LS40D, LS40TD, LS50TD, and LS600 Mayco concrete pump models, covering a wide range of hydraulic-driven units in the lineup.
- Cooling System Integrity — Properly sealed and routed ducting maintains the thermal balance needed to keep hydraulic components and the drive engine operating within safe temperature ranges during continuous pumping cycles.
- Verified Part Number — Part number EM511019 cross-references directly to the Multiquip Mayco LS-series parts catalog, eliminating guesswork when ordering a replacement.
Air ducting channels and directs airflow to critical heat-generating components — typically the engine, hydraulic system, or both — within an enclosed pump housing. On hydraulic-driven concrete pumps like the Mayco LS series, maintaining proper airflow is essential to preventing overheating during extended pour operations, which can cause hydraulic fluid degradation or engine thermal shutdown. When the ducting cracks, collapses, or becomes dislodged, cooling efficiency drops sharply and the risk of heat-related component failure increases significantly.
