The ERP75 compressor air filter 3/8 NPT is a complete replacement intake filter assembly designed for compatible rocking piston compressors with a 3/8 threaded inlet.

A clean, correctly fitted intake filter helps reduce the amount of dust and debris pulled into the compressor during operation. By maintaining proper filtration at the intake, you support consistent performance and help protect internal components from premature wear caused by airborne contaminants. This replacement unit is intended for Stratus ERP compressor applications that use a 3/8 NPT connection, making it a practical choice when your existing filter is damaged, clogged, or due for routine service.

Key benefits

• Direct-style replacement: Complete air filter assembly for 3/8 threaded inlets (NPT).
• Supports cleaner intake air: Helps capture common particulates before they enter the compressor.
• Service-friendly: Ideal for regular maintenance intervals to help keep airflow consistent.
• Application fit: Intended for ERP compressor setups that specify a 3/8 NPT inlet.

How to choose and install

Confirm your compressor model and inlet thread size before ordering. This product is specified for a 3/8 threaded inlet; if your system uses a different port size or adapter, choose the matching filter configuration. During installation, ensure the connection is clean and that the filter is seated securely to avoid air leaks. Replace the filter if it becomes visibly dirty, airflow seems restricted, or as part of scheduled upkeep.

For maintenance accuracy and long-term reliability, use the ERP75 compressor air filter 3/8 NPT as the correct intake filtration component for compatible ERP75 compressor installations. Keeping a spare ERP75 compressor air filter 3/8 NPT on hand can reduce downtime when service is needed.
