Many open‑loop circulating‑water systems face continuous impurity accumulation problem. Manual‑disassembly cleaning brings frequent system‑halt loss. LFZ Series Automatic Self‑cleaning Filter adopts internal brush‑type cleaning mechanism, which completes screen‑scraping and sewage‑discharge automatically while equipment keeps running. This whole set equipment belongs to complete water‑treatment unit matched with Water Filter Element consumable accessories. It is widely deployed for cooling‑tower circulating‑water, agricultural irrigation raw‑water, river/lake raw‑water pre‑treatment, paper‑mill white‑water and power‑plant auxiliary‑water loop. No need to stop downstream production flow during self‑cleaning procedure.

One typical scenario is cooling‑tower circulating‑water for steel‑mill and chemical‑plant. Wind‑blown dust, algae and rust continuously enter circulating pipeline; blockage will happen to heat‑exchanger nozzle without continuous filtration. LFZ self‑cleaning filter intercepts these contaminants and executes brush‑scraping automatically, no need worker to open housing. Another large application is agricultural drip‑irrigation system for park and farmland, filtering river/reservoir raw‑water to prevent drip‑hole blockage. Paper‑mill white‑water recovery and power‑plant ash‑removal circulating‑water are also mature application fields. High Flow Filter Cartridge can cooperate as fine‑polishing unit after this coarse self‑clean filter.
Automatic cleaning triggered by differential‑pressure or fixed‑timer avoids human‑operation error; production‑line does not need to shut‑down during sewage‑discharge. Stainless‑steel filter‑screen can be reused long‑term, largely reducing consumable‑replacement cost comparing to disposable‑cartridge solution. Modular control cabinet supports local manual operation and remote signal feedback for central‑control‑room monitoring. Multiple screen‑precision selections adapt different raw‑water impurity‑content. Welded pressure‑vessel shell meets industrial‑site pressure‑safety requirement. Oil Filtration Machine series also adopt differential‑pressure alarm logic for pollution‑blocking reminding.
Xinxiang Lifeierte Filter Corp.,Ltd (Stock Code:837936) completes whole‑machine design, pressure‑vessel welding, electric‑control assembly and overall testing in‑house. Every LFZ unit will pass pressure‑holding test and full‑cycle self‑clean function test before delivery. We support customized caliber, flow‑rate and screen‑material for special corrosive water quality. Spare parts including brush assembly, filter screen and solenoid‑valve can be supplied separately for after‑sales maintenance. replacement imported filter element division provides supporting spare‑part service for whole‑system solution.
Q1:Will water‑supply be interrupted during LFZ self‑cleaning cycle?
A1:No. The internal‑brush scraping and sewage‑draining process will not cut off main‑channel water‑supply, downstream equipment can keep running normally.
Q2:What kind of raw‑water is NOT fit for brush‑type self‑clean filter?
A2:Water containing large‑quantity soft fiber or sticky biological sludge may stick to screen and cannot be fully removed by mechanical brush; for such case, please consider back‑flush‑only‑type self‑clean filter solution.
Q3:What signals trigger automatic cleaning action?
A3:Two trigger modes: preset fixed time interval; or when inlet‑outlet differential‑pressure reaches set threshold value.
Q4:Can LFZ filter work under outdoor open‑air installation environment?
A4:Standard control‑box is indoor‑type. For outdoor scenario, we can provide rain‑proof and dust‑proof enhanced control‑cabinet option.
Q5:Do you supply complete spare‑parts for long‑term site‑maintenance?
A5:We provide separate spare‑part supply for filter screen, brush assembly, solenoid‑valve, pressure‑gauge and controller module.
