Generac Foam Screen Pre Filter #119701

Protect your Generac generator’s engine with an additional layer of filtration defense by replacing this Genuine OEM Foam Screen Pre Filter. Precision-manufactured to exact Generac factory specifications, this authentic foam pre-cleaner sits over the primary air filter cartridge — capturing larger dirt particles, dust, grass clippings, and debris before they ever reach the main filter element, significantly extending primary filter service life and maximizing engine protection during generator operation.

What the Foam Screen Pre Filter Does:
The foam pre-filter traps dirt along with the main air filter to prevent contamination inside the engine. It acts as the outermost layer of the engine’s air filtration system, intercepting coarse particles and debris that would otherwise load the primary paper filter element prematurely. By catching this first wave of contamination, the foam pre-cleaner keeps the main air filter element cleaner for longer — reducing the frequency of primary filter replacements and maintaining consistent, unrestricted airflow to the carburetor and engine throughout generator operation.

Why Genuine OEM Pre Filter Matters:
A foam pre-cleaner that is the wrong size, wrong density, or wrong shape can allow unfiltered air to bypass the main filter — exposing the engine directly to damaging dirt ingestion. The filter can be cleaned but eventually will need to be replaced as part of normal maintenance. Using the correct genuine OEM foam screen ensures a perfect, gap-free fit against the primary filter and air filter housing — no bypass, no gaps, no compromised engine protection.

Signs Your Foam Pre Filter Needs Replacement:

• Foam element torn, crumbling, compressed, or structurally deteriorated
• Foam heavily saturated with dirt, oil, or debris that cannot be cleaned out
• Pre-cleaner no longer fits snugly against the primary air filter housing
• Visible hardening, brittleness, or disintegration of the foam material
• Scheduled seasonal maintenance — replace pre-filter at the start of each season
• Primary air filter loading faster than expected — a failed pre-cleaner may be the cause

Key Features:

• Genuine Generac OEM part — not aftermarket or generic
• Foam screen construction captures coarse debris before it reaches the primary air filter element
• Extends the service life of the primary air filter cartridge by reducing its contamination load
• Precision-formed to fit flush against the OEM air filter housing with no bypass gaps
• Cleanable and reusable for multiple service intervals before requiring full replacement
• Lightweight, easy to remove and reinstall during routine maintenance

This foam screen pre-filter also fits the following Generac-branded generators: Honeywell, Guardian, Siemens, Carrier, Watchdog, Centurion, Eaton, and Bryant. Always confirm fitment using your generator model and serial number — found on the generator label or data plate — and cross-reference against your unit’s operator’s manual or Illustrated Parts List (IPL) before ordering to verify the correct pre-filter specification for your specific engine and air filter housing configuration.
