Automatic cleaning filters
Automatic cleaning filters
LiandaFiltration automatic self-cleaning filter integrates online backwashing and intelligent control to achieve continuous and uninterrupted self-cleaning filtration system operation. The core uses high-strength stainless steel filter element and rotating brushing device, which can automatically remove deposited impurities without disassembly. It is particularly suitable for the filtration needs of process water and circulating cooling water containing suspended particles. It is the first choice for enterprises pursuing high efficiency and energy saving.

FAQ
The timing mode (e.g. every 4 hours) or pressure differential trigger (ΔP ≥ 0.3 bar) automatic cleaning can be set according to the working conditions, which can flexibly adapt to various media.
The backwash system of LiandaFiltration intelligent self-cleaning filter accurately controls water consumption, which is only about 20% of traditional manual cleaning, saving significant water.
The equipment comes with universal casters and fixed brackets. It is recommended that the ground is flat and the power distribution is stable. If used in high temperature conditions, an insulation cover can be installed.
Under normal use, the filter element does not need to be replaced frequently. It is recommended to replace it every 12-18 months. The PLC system will remind you of maintenance based on the cumulative number of cleanings.
