444-8059: Filler Breather

The Filler Breather is used to regulate the pressure inside the exhaust unit. It allows the release of excess pressure that may build up due to temperature changes, exhaust gas flow, or other factors. By maintaining the pressure within a safe range, the breather helps prevent damage to the exhaust unit parts. It helps to exchange air between the inside and outside of the exhaust unit. Attributes: • Sufficient airflow capacity allows for the desired air exchange and pressure regulation • Manufactured to precise specifications and are built for durability and reliability Applications: The Filler Breather maintains atmospheric pressure within the Diesel Exhaust Fluid (DEF) tank, preventing pressure buildup or collapse due to temperature fluctuations or fluid level changes. This ensures smooth Diesel Exhaust Fluid (DEF) transfer from the tank to the injection system.
