The Wacker Neuson is a genuine OEM Breather Valve designed for a range of Wacker Neuson equipment including the CRT36-24A ride-on concrete trowel series, RD12A-90 tandem roller, BFS 2020AS floor saw, RD11A and RD11AEC vibratory rollers, and GS12Ai portable generator. As a factory-sourced component, the is manufactured to the same specifications as the original part, ensuring a direct, compatible installation across all listed models. Sourcing a genuine OEM Breather Valve means you get the exact component your machine was built with — no guesswork, no fitment uncertainty. Keep your equipment running at its best by replacing a worn or failed breather valve with the correct Wacker Neuson part.
Key Features
- Genuine OEM Venting Integrity — Manufactured by Wacker Neuson to precise venting tolerances, ensuring proper crankcase or reservoir pressure regulation specific to these engine and hydraulic applications.
- Direct Drop-In Installation — Engineered to match the original mounting port and thread specification, allowing straightforward replacement without modification to the existing assembly.
- Broad Model Coverage — Fits the CRT36-24A ride-on trowel family, RD12A-90 tandem roller (including foldable ROPS variant), RD11A and RD11AEC vibratory rollers, BFS 2020AS floor saw, and GS12Ai portable generator.
- Protects Internal Components — A functioning breather valve prevents pressure buildup and contamination ingress; a failed unit can lead to seal damage, oil leaks, or accelerated internal wear across the host system.
- Fuel and Fluid System Safety — Proper crankcase venting is essential to prevent overpressure conditions that can compromise gaskets and seals, making this a safety-relevant replacement on engine-equipped machines.
A breather valve regulates internal pressure within an engine crankcase or hydraulic reservoir by allowing gases to escape while preventing outside contaminants — dirt, moisture, and debris — from entering the system. Without a properly functioning breather valve, pressure can build beyond design limits, forcing oil past seals and gaskets and causing leaks or accelerated component wear. When the valve becomes clogged, cracked, or fails to seat correctly, the resulting pressure imbalance can lead to oil consumption issues, seal failure, and costly internal damage, making timely replacement with a correct-spec part critical to long-term machine health.
