PRE-FILTER
Ingersoll Rand 99331811 Prefilter Foam Element
Ingersoll Rand 99331811 is a durable prefilter foam element engineered to intercept coarse dust, airborne fibers, and large particulates at the compressor air intake.
Part Number
99331811
Product Type
Prefilter Foam Element
Application
Air Compressor Intake & Enclosure Panels
The 99331811 prefilter foam element provides essential first-stage barrier protection for compressor air intake paths. Its porous foam construction captures heavy environmental contaminants before they reach the internal primary filter, maintaining consistent volumetric airflow and extending overall filter element lifespan.

Product Information
High-Airflow Foam Media Protection
Engineered with high-permeability open-cell foam, the 99331811 prefilter foam element traps lint, ambient dust, and coarse debris without creating restrictive intake drop pressure. By filtering incoming process air before it strikes downstream primary elements, it preserves intake system efficiency in heavy-duty plant conditions.
Thermal & Filter System Longevity
Allowing particulate build-up at intake vents increases compressor power consumption and causes thermal stress on internal drive components. Timely replacement of the 99331811 foam element preserves smooth air delivery, prevents cabinet heat retention, and reduces total primary filter replacement costs.
