Self-cleaning Filters

The cleaning process of a filter involves using a plunger or a series of scrapers to remove impurities caught on the filter element. The captured particles are scraped into a sludge chamber at the bottom of the filter, where they are drained away from the filter. The drainage takes place through the bottom valve, which can be set to be activated after a certain number of scrapings. The cleaning cycle can be controlled through an electronically automated system, a pneumatically operated control system or a manual system depending on the model. As impurities are concentrated before being pushed out of the filters, product loss is reduced to the minimum. The flow through the filter is continuous during the cleaning process, allowing an uninterrupted production and improving lifetime of the filter element.

Self-cleaning filters can help to eliminate downtime to clean manually or to change filter elements; cut costs on maintenance and replacement of filter elements and improve productivity and quality of the manufacturing process. The simple yet robust and reliable construction makes the filters easy to service and suitable for applications with limited spaces.
