Brush self-cleaning filter

Product Details

product description

LH-SZ series brush type self-cleaning filter is a device that uses filter screen to intercept impurities in the liquid and has the function of automatic cleaning and drainage. It adopts modular design, compact structure, excellent performance, and the system is constantly water during cleaning and drainage.

working principle

LH-SZ series brush self-cleaning filters are controlled by the pressure difference between the inlet and outlet. When the pressure difference reaches a preset value, self-cleaning starts: the sewage valve opens, the reduction motor drives the cleaning brush to rotate, and the impurities intercepted on the filter are brushed off. Discharge through the drain.

structure type

Type Y: The equipment is imported and exported on a straight line, which can be installed horizontally or vertically, suitable for installation in the straight pipe section of the system.

Type L: The equipment inlet and outlet are at an angle of 90 °, which can be installed vertically or horizontally, which is suitable for installation in the corner of the system pipeline.

Type F: The inlet and outlet of the equipment are perpendicular to the body and face the same direction. It can be installed vertically or horizontally. It is suitable for installation in straight pipe sections with insufficient space at the bottom or side.
