Product Overview
The Ingersoll Rand 47623611001 / 47569978001 Gasket Pre-Filter is a high-quality compressor intake pre-filter designed to provide primary filtration for Ingersoll Rand rotary screw air compressors. Installed ahead of the main air filter element, the pre-filter captures larger airborne contaminants before they reach the primary filter, significantly extending filter service life and improving overall compressor efficiency.
As an essential component of the compressor air intake system, the 47623611001 / 47569978001 reduces the accumulation of dust, fibers, insects, leaves, and coarse particles on the primary air filter. By minimizing contaminant loading, it helps maintain stable airflow, reduces pressure drop across the filtration system, lowers maintenance frequency, and protects critical compressor components from premature wear.
Manufactured from durable, high-efficiency filtration material with an integrated gasket design, the pre-filter provides reliable sealing and consistent filtration performance even under demanding industrial operating conditions. It is well suited for installations exposed to heavy dust concentrations, outdoor environments, mining operations, cement plants, woodworking facilities, and other harsh industrial applications.
With dimensions of 10 × 530 × 740 mm and an approximate weight of 0.75 kg, the 47623611001 / 47569978001 is lightweight, easy to install, and designed for periodic replacement as part of routine compressor maintenance.
Typical applications include manufacturing plants, mining operations, cement production, woodworking facilities, power stations, food and beverage processing, chemical plants, pharmaceutical factories, textile mills, and other industrial compressed air systems.
