Mobile App
Put this site on your phone or tablet. The app carries the website you are looking at now: the model data, the technical articles and the contact details all come from the same content, so the app follows the website when it is updated and does not need a separate release.
A client that carries this site and nothing else
The app stores no business data and has no account system. What opens is the content of this site. All the technical data, the test references and the fault-finding steps are the same as on the web: a colleague checking the data on a phone in the workshop and another reading the detail on a computer are looking at the same thing.
It runs on Android 5.0 and above, in landscape and in portrait, and the same package is used on phones and tablets. The package is about 10 MB and the whole site is inside it, so once it is installed the app opens without a network and the parameters can still be looked up where the signal in the workshop is poor. If the network is down it offers a retry instead of the browser's default error page.
Scan the code with your phone
Scan the code with the camera or the browser on your phone and the package goes straight into the download list.
What you get once it is installed
The model data at hand
The throughput, the vacuum level, the filtration accuracy, the water content and the breakdown voltage of the 14 models on sale are listed by model, so you can go through them category by category instead of searching through a table.
Technical articles available offline
About 100 articles on the vacuum degassing principle, the element replacement interval, the water content and breakdown voltage tests and the order for fault-finding on site can be called up in the workshop when there is no signal.
Calls and mail go to the system
The call button on a page calls the system phone app and the mail button opens the system mail client. The contact channels are the applications already on your phone; the app does not build a second set of its own.
Files go straight to the download folder
When a manual or an image has to be downloaded, the app hands it to the system downloader, which saves it in the download folder of the phone and takes nothing from the storage of the app itself.
Installation requirements
The package is one universal apk. Phones and tablets use the same file, so there is no separate download per screen size.

The table holds the actual parameters of the package, and the app shows the same. No package is offered for iOS or iPadOS at the moment.
The package is about 10 MB because the whole site is inside it: once it is installed the app opens without a network and never waits for a slow connection. After that one download, every start reads the local files. The package is updated once a week, with the same signing key, so it can be installed straight over the old one without uninstalling.
Installation steps
- Open this page on an Android phone and tap the download button in the corner or the download link above, or scan the code on the right with the camera.
- When the download has finished, tap the package file. The first time, the system warns that installing from unknown sources is blocked. Follow the prompt into the settings and allow installation once for the browser or file manager you are using.
- When the installation has finished, the Yanneng Oil Filter icon is on the home screen. Opening it shows the content of this site.
The package is signed by the company itself. Later versions are published with the same signing key, so they install straight over an earlier version without uninstalling. If an older version is already on the phone, download the new one and install it over the top.
If the download does not start, send the package link to a computer and download it there, or call 400-023-9089 with the model and the system version and we will help.
