Automatic Filter F400/ F440

The self-cleaning Automatic Filter F490 is electrically/pneumatically operated and used for the separation of solids in various different media like cooling water, process water or water in water treatment. The Filter ensures reliable and continuous filtration in a variety of applications.

The automatic filter F400 and F440 consist of a welded or cast (G) housing. The cleaning cycle is initiated by defined time interval or differential pressure. Depending on the actual operational conditions the cleaning cycle can also be initiated manually. During the cleaning cycle the backflush valve opens and creates a pressure drop towards the atmospheric pressure. Simultaneously the flushing nozzle will travel along the inner surface of the strainer insert. This ensures an effective cleaning of the strainer. The filtration will not be interrupted during the entire cleaning cycle. The backflush valve closes automatically at the end of the cleaning cycle.
