Thermo King Roanoke line of Air Intake Cleaners from Sy-Klone, allow for added horsepower, torque and air filter life and have a positive impact on vehicle efficiency, power, acceleration and maintenance.

The air flow that goes into the engine is controlled by the air intake system. For increased power and speed, the engine must get the proper air flow. Our line of Air Intake Cleaners remove dirt before it gets to the air filter. From noise, to sticking parts, to slower acceleration, having a dirty air intake can dramatically affect the efficiency of one’s vehicle.

The technologically advanced air intake cleaners that Thermo King Roanoke provides do not allow for dirt, dust, and contamination to rob your equipment of efficiency or your company’s profitability.

Series 9000 PhotoIncludes Precleaner and clamp. Please check the Series 9000 Sizing Wizard to confirm that you are ordering the correct model precleaner, as precleaner size is determined by airflow requirements, not your machine’s air inlet size. The Sizing Wizard will also specify whether or not your machine will need an installation kit.

Air filter life is directly related to the amount of debris ingested through an engine’s air intake. Installing a Sy-Klone Series 9000® Air Precleaner as the first stage of an air intake system prevents the majority of heavier-than-air particles from entering the system. This results in longer air filter life, more efficient engine performance and decreased maintenance expenses. See how much YOU can save by using the online Series 9000 Savings Calculator.
