Function of the Filter Felt

The AC-0333 Filter Felt O/L is an essential component of the compressor's air intake system. It helps to:

• Filter dust and debris from incoming air
• Protect internal pump components from contamination
• Maintain unrestricted airflow into the compressor
• Improve compressor efficiency and performance
• Extend the service life of the compressor pump
• Restore the compressor's original intake filtration performance

Using a genuine OEM replacement filter felt helps ensure proper airflow, dependable filtration, and long-lasting compressor operation.

Common Signs Replacement Is Needed

Replace the filter felt if you notice:

• Dirty or clogged filter media
• Reduced compressor performance
• Decreased airflow into the pump
• Visible tears or deterioration in the felt
• Excessive dust buildup
• Increased pump operating temperature

A clogged or damaged intake filter can restrict airflow, reduce compressor efficiency, and accelerate wear on internal pump components.

Installation & Service Notes

Turn off the compressor, disconnect the spark plug wire or power source as applicable, and completely bleed all air pressure from the tank before performing maintenance.

Remove the air cleaner housing or filter cover according to the manufacturer's service instructions. Remove the old AC-0333 Filter Felt O/L, clean any accumulated dust or debris from the filter housing, and install the new felt filter in the same orientation. Reinstall the filter cover securely and verify that all components are properly seated before returning the compressor to service.

Important: Always verify your compressor model, type number, and original part number before ordering. Inspect the filter housing and intake components during routine maintenance, and replace the filter whenever it becomes excessively dirty or damaged. Using a genuine OEM DeWalt replacement filter helps maintain proper airflow, protect the compressor pump, and maximize equipment longevity.

Maintenance Recommendations

• Inspect the intake filter before each period of extended compressor use.
• Replace the filter whenever it becomes clogged, damaged, or oil-soaked.
• Keep the air intake housing clean and free of debris.
• Operate the compressor in a clean, dry environment whenever possible.
• Follow the manufacturer's recommended maintenance schedule for intake filter replacement.
• Use genuine OEM replacement parts to maintain factory fit, clean airflow, and long-term air compressor performance.
