Large bore filter

Automatic cleaning filter

|Product introduction

1. Automatic washing system
When impurities block the tube of filter, the automatic washing system is turned on, removing the impurity from the filter to regenerate the filter. Meanwhile, the impurities are collected in the tank under the filter and are finally emitted from the outfall.
2. Control System
The auto-cleaning equipment is controlled by a timer. When time is up, the auto-cleaning equipment will be turned on automatically. Also auto-cleaning system can be controlled by a differential pressure sensor, but a timer-controlled system is recommended.

|Installation and maintenance

1, the core part of the filter is a filter core, filter by the filter box and stainless steel wire mesh, stainless steel wire mesh is a suitable loss, need special protection;
2, when the filter for a period of time, the filter core precipitation of a certain impurity, then the pressure drop increases, the flow rate will drop, need to promptly remove impurities in the filter core;
3, cleaning the impurities, especially pay attention to the filter on the stainless steel wire mesh can not be deformed or damaged. Otherwise, then installed filters, filter medium purity is not up to the design requirements, compressors, pumps, instruments and other equipment will be destroyed.
4, such as the discovery of stainless steel wire mesh deformation or damage, need to be replaced immediately.

|Order notice

Order shall be determined by the following parameters: diameter; work pressure; (3) material; (4) flange standard; dielectric; the operating pressure; to give you provide suitable products.
