Multiquip 1180870 Air Filter Inner F4L1011 - OEM Replacement Part

The inner air filter protects the Deutz F4L2011 and BF4L2011 diesel engines powering structural concrete pumps from dust, debris, and contaminants that can cause premature wear and engine failure. This critical filtration component works in tandem with the outer air filter element to provide two-stage protection for engine intake air, preventing abrasive particles from reaching cylinder walls, pistons, and valves during demanding concrete pumping operations.

Designed specifically for the Deutz F4L1011 engine series, this inner air filter maintains optimal airflow while capturing fine particulates that bypass the primary filter element. Regular replacement of both inner and outer air filters is essential for maintaining engine performance, fuel efficiency, and preventing costly engine damage on concrete pump equipment operating in dusty jobsite conditions. Clogged or damaged inner filters can restrict airflow, reduce engine power, and allow contaminants to enter the combustion chamber.

Compatible with the following Multiquip concrete pump models:

• LS-40
• LS-40TD
• LS-50TD
• LS400
