Product Overview
The Ingersoll Rand 47704439001 / 47569978001 Gasket Pre-Filter is a high-quality compressor intake pre-filter and sealing gasket designed to provide primary air filtration while ensuring an effective seal within the intake filtration system of Ingersoll Rand rotary screw air compressors. As an essential preventive maintenance component, it protects the primary air filter from excessive contamination and prevents unfiltered air from bypassing the filtration system.
Installed at the compressor air intake assembly, the 47569978001 Gasket Pre-Filter captures larger airborne contaminants such as coarse dust, fibers, insects, and debris before they reach the primary intake air filter. This staged filtration design extends the service life of the main filter element, maintains stable airflow, and reduces overall maintenance frequency.
In addition to its filtration function, the integrated gasket provides an airtight seal between filter components, preventing leakage of contaminated ambient air into the compressor. Maintaining proper sealing is critical for protecting sensitive internal components including the intake valve, airend, rotor assembly, oil separator, oil filter, and lubrication system.
Manufactured from durable industrial-grade filtration and sealing materials, the 47704439001 / 47569978001 is engineered to withstand continuous operation in dusty manufacturing environments while maintaining low airflow resistance and excellent sealing performance.
With dimensions of 457 × 15 × 304 mm and an approximate weight of 0.45 kg, this gasket pre-filter is ideal for scheduled preventive maintenance across a wide range of industrial compressed air applications.
Typical installations include manufacturing facilities, automotive plants, mining operations, cement production, woodworking factories, food and beverage processing, pharmaceutical manufacturing, metal fabrication, chemical processing, and other industrial compressor systems.
