Multiquip 4384102 Air Filter Cartridge

The Multiquip 4384102 Air Filter Cartridge is a genuine OEM replacement designed for LS40D, LS40TD, and LS50TD hydraulic-driven concrete pumps. As a factory-sourced component, it meets the exact filtration specification required to protect the engine on these machines. This is the correct OEM cartridge for operators who need a direct, verified replacement to get their pump back in service. Confirm your model code against the fitment list before ordering.

Key Features

• OEM Filtration Media: — Manufactured to the exact porosity and surface area specification of the original, ensuring consistent engine air flow and contaminant capture on these concrete pump models.
• Direct Housing Match: — Sized and sealed to fit the factory air filter housing on LS40D, LS40TD, and LS50TD units without trimming, shimming, or adapter hardware.
• Confirmed Fitment: — Verified for Mayco LS-series hydraulic concrete pumps — LS40D, LS40TD, and LS50TD model codes.
• Engine Protection at the Air Intake: — A correctly seated, in-spec cartridge prevents dust, aggregate fines, and jobsite particulates from reaching the engine intake, helping sustain compression and reducing internal wear over time.
• Fuel Efficiency Maintained: — A clean, unrestrictive air filter holds the correct air-to-fuel ratio; a clogged or under-spec cartridge causes rich running, increased fuel consumption, and hard starting.

The air filter cartridge sits between the open atmosphere and the engine's intake system, trapping dust, fine aggregate particles, and airborne debris before they can enter the combustion chamber. On a concrete pump operating in a dusty pour environment, the filter works hard and loads up quickly — a cartridge that is past service life or incorrectly sized allows abrasive particles to bypass the intake seal and accelerate cylinder and valve wear. Replacing the 4384102 on schedule with a genuine OEM cartridge ensures the engine breathes cleanly and maintains the power output needed to drive the hydraulic pump circuit at full working pressure.
