Sizing
Formula
■ Based on the engine intake parameters provided by the engine factory, select a pre filter that is suitable for this flow parameter;
■ If the manufacturer or user does not have relevant engine intake flow parameters, please calculate the intake volume as follows.

CFM - Cubic Feet Per Minute
CMM – Cubic Meters Per Minute
L- Liters
RPM - Revolutions Per Minute
CID – Cubic Inch Displacement

Conversion Formula for Metric Displacement to CID:
Cubic Centimeters (cm³) × 0.06102 =CID
Displacement in Liters × 61.02=CID
Conversion of CFM to CMM multiply by 0.0283
Installation
Guide
The air precleaner is sized according to the engine airflow ratings and not according to the air intake pipe size.
The air precleaner must not be mounted flush against any surface of the equipment as clearance is needed for the discharge of debris, dirts, dust. A minimum clearance of 5cm is recommended.
For optimum results, vac valves, rubber valves on the filter canister, air intake system should be properly sealed/closed to prevent contaminated air from by-passing the precleaner.
Hump hoses are strongly recommended for air precleaner installed in high vibration applications.
KleanAire precleaners are self-powered & self-cleaning and it virtually requires no maintenance. However, the discharge ports should be checked periodically to ensure that it is not plugged by debris, dirt, mud (especially in moist environment)
For optimum results, vac valves, rubber valves on the filter canister, air intake system should be properly sealed/closed to prevent contaminated air from by-passing the precleaner.
