The Wacker Neuson Ventilator Breather is a genuine OEM component designed for KTU and FUE series frequency converters, including the KTU 2/042/200W, FUE 2/042/200W, FUE 1/042/200W, FUE 2/250/200W, FUE 1/120/200W, KTU 2/250/200W, KTU 1/042/200W, and KTU 1/120/200W. Sourced directly from Wacker Neuson, this part meets the exact specifications of the original component it replaces. Verify your model number before ordering to ensure a correct, direct-fit installation.
Key Features
- Genuine OEM Venting Performance — Manufactured by Wacker Neuson to the original ventilation and pressure-equalization specification, ensuring the breather functions exactly as the converter's enclosure design requires.
- Drop-In Replacement — Matches the original mounting interface and port dimensions of the 5000201221, so installation follows the same procedure as the factory-fitted unit.
- Broad KTU and FUE Series Coverage — Confirmed fitment across eight KTU and FUE converter models in the 042 and 250 input ranges, covering both single- and dual-output configurations.
- Protects Internal Components — A properly functioning breather regulates pressure differentials inside the converter housing, preventing moisture ingress and condensation buildup that can damage sensitive electrical components over time.
- Electrical Safety Integrity — Maintaining correct enclosure ventilation is directly tied to safe converter operation; a failed or blocked breather can compromise moisture protection ratings and create conditions for internal corrosion or insulation degradation.
A ventilator breather allows a sealed or semi-sealed enclosure — such as a frequency converter housing — to equalize internal air pressure as temperatures rise and fall during operation and cooldown cycles. Without a functioning breather, pressure differentials can draw unfiltered air and moisture into the housing, accelerating corrosion and shortening the service life of internal electrical parts. Replacing a worn or blocked breather restores proper pressure management and helps maintain the environmental protection the converter enclosure was designed to provide.
