It can efficiently intercept suspended solids, particulate matter, sediment, impurities and other pollutants in fluids/gases, and stably guarantee filtration accuracy and discharge quality.

This equipment balances universality and customization, which can not only meet the basic filtration needs of conventional working conditions, but also adapt to complex and harsh scenarios such as high impurity content, high viscosity and continuous production. It is a core equipment for reducing costs, improving efficiency and optimizing filtration processes in industrial production, municipal operation and maintenance, agricultural irrigation and other fields, effectively solving the industry pain points of traditional filtration equipment such as frequent blockages, cumbersome operation and maintenance, and high operating costs.

Technical Features

Intelligent Dual-Control Self-Cleaning System: Equipped with a differential pressure induction + timing dual-mode control module, it can monitor the accumulation of impurities on the filter screen in real time. When the inlet and outlet differential pressure reaches the set threshold or the operation reaches the preset time, the cleaning procedure is automatically triggered without manual startup. It features high intelligence, adapts to 24-hour uninterrupted operation requirements, and completes the entire process of self-cleaning and sewage discharge without additional external energy.

High-Precision Customizable Filter Screen: Adopts high-quality filter materials such as wedge wire and stainless steel woven mesh, with a flexibly customizable filtration accuracy ranging from 5μm to 3000μm. It can not only achieve micron-level precision filtration to meet high-standard purification requirements, but also adapt to coarse filtration scenarios, balancing filtration efficiency and interception effect. The filter screen has uniform pores, avoiding impurity jamming and leakage, ensuring stable filtration performance.

Uninterrupted Operation Design: Adopts partition polling cleaning and online backwashing technology, eliminating the need for shutdown and flow interruption during cleaning and sewage discharge. The filtration system maintains continuous operation at all times, avoiding production interruptions caused by equipment maintenance. Compared with traditional filters, it greatly improves overall operating efficiency, especially suitable for industrial production lines with extremely high continuity requirements.

Corrosion-Resistant and Wear-Resistant Durable Materials: The main frame, filter screen and sewage discharge components are made of corrosion-resistant and wear-resistant materials such as 304/316L stainless steel. It can adapt to various media including water, chemical liquids, acid-base containing fluids and dust-containing gases, resisting erosion from harsh working conditions. The service life of the equipment far exceeds that of ordinary filters, with no deformation or rust during long-term operation.

Low Pressure Loss & Energy-Saving Structure: Optimizes the fluid/gas flow channel design to reduce pressure loss during filtration, cutting down energy consumption for fluid transportation and fan operation. It is also equipped with a high-efficiency sewage discharge structure, featuring short self-cleaning and sewage discharge time and low water/gas consumption, further reducing operating energy consumption and meeting the needs of energy-saving and environmentally friendly production.

Core Advantages

Compared with traditional bag, basket and core filters, the core advantages of this self-cleaning filter focus on three dimensions: cost reduction, efficiency improvement and convenience, fully adapting to customers' actual usage needs. Firstly, significantly reduces operation and maintenance costs: no manual disassembly, cleaning, filter element replacement or supervision is required, saving labor costs and filter element consumables costs, with annual operation and maintenance costs reduced by more than 60%. The filter screen is reusable, eliminating consumable waste. Secondly,ensures production continuity: the non-shutdown self-cleaning design avoids production interruptions, reducing capacity losses caused by filtration failures, especially suitable for large-scale and continuous production scenarios. Thirdly, stable and controllable filtration effect: the intelligent self-cleaning technology keeps the filter screen clean at all times, preventing the decline of filtration accuracy and flow attenuation caused by impurity accumulation, and the filtration effect remains up to standard during long-term operation. Fourthly, strong scenario adaptability: specifications can be customized according to media type, working conditions and flow demand, with flexible installation methods and no need for major modification of existing pipelines, enabling convenient deployment. Fifthly, outstanding environmental protection and energy-saving properties: low-energy operation and low sewage discharge loss conform to the global trend of green industrial production, while reducing operational risks caused by manual operation and maintenance.

Frequently Asked Questions (FAQ)

Q1: What is the cleaning principle of the self-cleaning filter, and will the cleaning process affect the filtration effect?

A: The equipment triggers automatic backwashing and suction cleaning processes through differential pressure or timing, relying on hydraulic/pneumatic power to complete impurity cleaning and sewage discharge on the filter screen. It adopts a partition polling cleaning design, with only part of the filter screen working during cleaning and the rest operating normally. There is no flow interruption or shutdown throughout the process, which will not affect the overall filtration effect and flow stability.

Q2: Does the equipment require regular maintenance, and is the daily maintenance cost high?

A: No frequent manual maintenance is required in daily use, only regular inspection of the sewage discharge pipeline and filter screen loss is needed, with a long maintenance cycle. There is no need for consumable replacement, and only a small amount of electric/hydraulic power is needed to support the self-cleaning process. The daily operation and maintenance costs are extremely low, far lower than traditional filters.
