Multiquip 17218ZE0505 Outer Filter

The Multiquip 17218ZE0505 is a genuine OEM Outer Filter designed for a wide range of Multiquip, Whiteman, Essick, and STOW equipment sharing a common Honda engine air filtration platform. This OEM-sourced component delivers a direct, drop-in fit across concrete mixers including MC42S, MC44SH, MC44SE, and CMS-4S models, walk-behind trowels including the CA4HC, CA4HM, and CA4.4HM series, centrifugal and diaphragm pumps including QP2H, QP303H, MQD2H, and MQ-D306HA, and plate compactors including the MVB85H. As a genuine OEM part, the part meets the original design specifications set for every machine it fits, so there is no guesswork on compatibility or performance.

Key Features

• Genuine OEM Air Filtration Media — Sourced directly from Multiquip, this outer filter meets the original pore structure and filtration efficiency spec required by the Honda engine platforms used across this equipment family.
• Wide Cross-Equipment Compatibility — A single part number covers concrete mixers, walk-behind power trowels, centrifugal pumps, diaphragm pumps, and plate compactors across the Multiquip, Whiteman, Essick, and STOW lines including MC44SH, CA4HM, QP2H, MVB85H, and more.
• Direct Drop-In Installation — Matches the original housing dimensions and retention method, seating securely against the inner filter element without adaptation or trimming.
• Protects Engine Performance Under Load — A fully functioning outer filter prevents abrasive dust and debris from bypassing the air intake, keeping combustion clean and engine output consistent during heavy compaction, mixing, or pumping cycles.
• Fuel System and Engine Protection — A clogged or degraded outer filter allows particulate contamination into the carburetor and combustion chamber, accelerating wear and increasing the risk of hard-start conditions or power loss mid-task.

The outer air filter is the first line of defense in the engine's air intake system. It wraps around the inner filter element and captures larger airborne particles — dust, sand, and debris — before they can reach the finer inner filtration stage or enter the carburetor. On jobsites where concrete dust, aggregate fines, and soil particulates are constantly airborne, this filter works continuously under load. When the outer filter becomes clogged or torn, the engine runs rich, loses power, and risks accelerated internal wear from unfiltered air bypassing the intake. Regular inspection and timely replacement of the part keeps the air intake flowing correctly and extends overall engine service life across all compatible equipment.
