Internal air filter for Hahn & Sohn Diesel Generator HDE20SS3-DW

The inner air filter represents an important safety component of the intake system of the generator engine. This filter is designed for the Hahn & Sohn HDE20SS3-DW model and functions as a second stage of filtration behind the main (outer) filter.

• Its main task is to capture fine dust particles that may pass through the primary filter, thereby maximally protecting the engine from wear and damage. The inner filter is especially crucial when operating in extremely dusty environments or in case the outer filter becomes clogged or damaged.
• Thanks to its construction from high-quality filter material, it ensures high filtration efficiency while maintaining sufficient airflow. The proper function of this filter has a significant impact on engine lifespan and the overall reliability of the generator.

WHY CUSTOMERS CHOOSE IT
