Multiquip D4374100003 Air Cleaner Hose - OEM Replacement Part

The air cleaner hose is a critical component that connects the air filtration system to the engine intake on Multiquip welders, ensuring clean, filtered air reaches the combustion chamber while preventing dust, debris, and contaminants from entering the engine. This hose must maintain an airtight seal to prevent unfiltered air from bypassing the air cleaner element, which could cause premature engine wear, reduced performance, and potential engine damage.

Designed specifically for demanding welder applications, this OEM air cleaner hose is engineered to withstand exposure to heat, oil vapors, and vibration common in industrial welding environments. A degraded or cracked air cleaner hose can lead to poor engine performance, increased fuel consumption, rough idling, and contamination of internal engine components. Regular inspection of this hose during routine maintenance intervals is essential for maintaining optimal engine performance and longevity.

This air cleaner hose is compatible with the following Multiquip welder models:

• DLW-400ESA4
• DLW-400ESA4F
• DLW330X2
