Type 4 B/C Blow-by System Upgrade
Upgrading to the latest blow-by filter design—used in our Jenbacher Type 4 D-/E-version engines—offers a smarter, more efficient solution for your Type 4 B-/C-version engines. This upgrade allows you to exchange only the filter cartridge, rather than the entire blow-by system—without compromising service intervals or engine performance
Upgrade for:
What can this upgrade do for you?
- Reduced import duties
With the blow-by system upgrade, only cartridges need to be exchanged throughout the engine’s lifetime—eliminating the need to order and import blow-by housings. - Lower life-cycle costs
Exchanging just the cartridge instead of the entire blow-by system results in lower overall life-cycle costs and reduced engine downtime. - Enhanced sustainability
The upgraded blow-by filter housing is designed to last for the engine’s entire lifetime. After the new blow-by filter has been installed, only the filter cartridges need to be exchanged— reducing waste and environmental impact.
How we get you there?
- Typical upgrade scope
The filter housing including filter cartridge, insulation, pipings and clamps—aligned with the design of Type 4 D-/E-versions— are included. - OEM documentation update
All installation changes resulting from this upgrade are reflected in the operating manual and spare parts catalog. - Recommended timing
This upgrade should be performed during the next scheduled blow-by filter replacement and can be integrated early in the engine’s life cycle
