The Multiquip 84002309 Air Filter is a genuine OEM component designed for CA4HC and CA5BC walk-behind power trowels and QP2TB and QP303B centrifugal pumps. As a direct OEM replacement, this air filter is manufactured to the same standards as the original part your machine left the factory with, ensuring a proper fit and correct airflow performance across all compatible models. Sourced directly through authorized Multiquip supply channels, part number 84002309 is the correct service replacement for operators maintaining any of these machines.
Key Features
- OEM Filtration Media: — Manufactured to the original filtration rating, trapping dirt and debris at the same efficiency level as the factory-installed unit to protect engine internals.
- Drop-In Replacement: — Engineered to seat and seal exactly like the original, using the same housing interface on CA4HC, CA5BC, QP2TB, and QP303B models — no trimming or adapting needed.
- Broad Fitment Coverage: — A single part number covers both walk-behind power trowel and centrifugal pump applications, making it a practical stocking item for mixed fleets.
- Engine Protection at Every Hour: — A clean, properly seated air filter maintains the air-to-fuel ratio your engine needs to run efficiently; a clogged or wrong-size filter accelerates wear on cylinder walls and piston rings.
- Fuel System Integrity: — Correct filtration prevents particulate ingestion that can disrupt carburetor function and cause hard-starting or rough running in gas-powered trowel and pump applications.
An air filter's job is to clean the air entering the engine before it reaches the carburetor and combustion chamber. By capturing dust, grit, and debris, it prevents abrasive particles from grinding against internal engine components. When an air filter becomes clogged or deteriorates, airflow is restricted, causing the engine to run rich, lose power, and consume more fuel — and if the filter media breaks down entirely, unfiltered air can cause accelerated internal engine wear. Regular replacement with the correct OEM part like the Multiquip 84002309 keeps combustion conditions optimal and extends engine service life.
