ENTARON XR: the self cleaning air cleaner
The elaborate and potentially risky manual cleaning of the air cleaner filter element with construction and agricultural machinery is now a thing of the past: The innovative self-cleaning air cleaner ENTARON XR from MANN+HUMMEL saves time and money for customers and protects the health of users. Premature engine wear is prevented. The first series application for the self-cleaning air cleaner is in the Fendt 900 and 1000 Vario series.
Air blows across a dusty field and time is in short supply as the harvesting has to be finished before the arrival of a thunderstorm. And to make matters worse the air filter element of the agricultural machine now has to be changed. Depending on the application, this can often be the case in extremely dusty regions. A failure to change the filter element means the engine will no longer be supplied with sufficient air and as a result will suffer a loss of performance or the fuel consumption will increase. If the air filter element is not easily accessible, changing the filter element can take a lot of time. It is frequent practice to manually clean the filter element with a mechanical process which can lead to the filter element being damaged. If the damaged filter element is subsequently used, this can lead to increased engine wear or even engine failure. This in turn can cause machine downtimes.
The ENTARON XR removes the need for machine operators to carry out this elaborate and time‑consuming work. This is because the MANN+HUMMEL air cleaner cleans itself. Unplanned or preventive manual cleaning is no longer necessary and users are not exposed to harmful dust particles. Machine operators benefit from this while the owners of agricultural and construction machinery also take advantage from lower maintenance costs, the extended service life of the filter, and the longer operating life of the innovative air cleaner. Using the ENTARON XR reduces your total costs of ownership.
Impulse cleaning technology
The advantages are convincing with a service interval which is up to 25 times longer, less manual service, reduced downtime and increased machine availability. To achieve this the filtration experts at MANN+HUMMEL further developed an existing product. The ENTARON XR is based on the proven ENTARON XD two-stage air cleaner. A solenoid valve connected to a compressed air reservoir triggers a compressed air pressure surge which is directed into the air cleaner through a nozzle. This results in a cleaning process which removes dust and dirt particles from the surface of the filter element. The user no longer has to be concerned about the right time for cleaning. A pressure sensor fitted to the air cleaner supplies a signal which automatically triggers impulse cleaning via the vehicle electronics. The dust released is then scavenged either by the ventilation or exhaust system.
Newly developed filter media
The ENTARON XR also convinces with its filter media. The media used is MICROGRADE A-C-ME F1 which is a new development and combines the durability of conventional cellulose‑based filter media with a high-performance PTFE membrane. The membrane prevents filter pores from being irreversibly clogged with fine dust particles and enables extremely good and consistently reproducible cleanability. In addition, the membrane provides excellent protection for the engine components against harmful dust. The separation efficiency for fine test dust is higher than 99.997%. As a result, the passage of dust is reduced by roughly a factor of fifty compared to conventional cellulose-based filter media.
First series application
The self-cleaning air cleaner will firstly be fitted as an option to Fendt 900 and 1000 Vario tractors. The user can manually initiate the cleaning cycle of 30 seconds or it can be carried out fully automatically and is signaled by a popup window on the display. More details on the application at Fendt are available .
