Introduction
Backed by decades of industrial manufacturing expertise,LEFILTER’s stainless steel self-cleaning filters leverage 304/316L corrosion-resistant construction, precision-engineered stainless steel scrapers (replacing traditional brushes for 40% longer service life), and intelligent dual-control automation (pressure-difference sensing + timed cleaning) to deliver uninterrupted filtration for critical industrial processes. Designed to handle flow rates from 10–500 m³/h across configurations—including multi-column, straight-through, and scraper-driven models—these filters remove particles as small as 5 μm, minimize energy loss with low-pressure drop, and eliminate consumable costs through self-cleaning technology. From power plant cooling systems to food and beverage production, they ensure consistent fluid purity in harsh environments while slashing maintenance labor by 80%.
The filter adopts mechatronics design. Automatic self-cleaning filter is composed of driving mechanism, control pipeline (including differential pressure switch), main component, filter component, cleaning mechanism, connecting flange and other main components. The control part of the filter is composed of an electronic controller, a control line and a blowdown valve, which is used to realize the automatic cleaning and blowdown process. The control pipeline is composed of differential pressure switch, pipe joint, brass pipe and other accessories. Conventional filter is equipped with a stainless steel brush, but you can also choose other types of brushes according to different usage conditions (water temperature, water quality).
1) The filter precision is 100 micron by default, and can be selected from 50 to 5000 micron. The filtering area is large and the pollution absorption is high. Users can customize the filter according to the actual working conditions.
2) The cleaning method is simple, and the cleaning cycle monitoring can realize automatic cleaning and sewage. All parameters of the automatic filter control system can be adjusted.
3) The filter is equipped with motor overload protection function, which can effectively protect the motor.
4) It has the characteristics of uninterrupted water supply and no bypass during cleaning and sewage discharge. Besides, the cleaning time is short and the sewage discharge consumption is less than 3% of the total flow.
5) Strong maintainability, easy installation and disassembly. The connection flange has strong versatility.

Application Fields
Agricultural irrigation-especially suitable for water sources with high impurity particlecontent.Sprinkler irrigation,dripinrigation,parks,golf courses,turfwatering drip irrigation treatment, etc.
Raw water treatment - surface river water, lake water, sea water, reservoir water, well water and ground water can be filtered to remove sand, algae,organic matter, etc.
Industrial circulating water filtration-used in equipment with certain requirements for water quality, such as: cooling towers, rolling mills, continuous casting machines, polishing, pumps, ion exchangers, sprayers, heat exchangers, etc. or supply and drainage pipelines, canfilter out impurities inwater to avoid blockage of pipelines,nozzles and other components.
Cooling water treatment -cooling towers, supplemental water systems, air conditioning systems, DC system water fltration, reducing the generation of sediment in heat exchangers and maintaining their cooling effect.
Paper industry-white water filtration.
Plastic industry -product recovery cooling water filtration.
Power industry-turbine cooling water filtration, power plant dust removal cycle ash water filtration.
Q&A: Your Concerns, Answered
Q1: Can the filter handle viscous fluids?
A: Yes. For high-viscosity media (e.g., lubricants), we recommend customizing the scraper design and motor torque to ensure effective cleaning.
Q2: How to select the right filtration precision?
A: Consider the particle size to remove and downstream equipment sensitivity. Our team provides free testing—send a sample, and we’ll advise the optimal precision.
Q3: What’s the warranty period?
A: 24 months for the entire system. The stainless steel scraper and filter element are covered for 12 months under normal use.
Q4: Can it be integrated with PLC/DCS systems?
A: Absolutely. The filter’s control panel supports MODBUS communication, enabling seamless integration with industrial automation networks.
