Bernoulli self-cleaning filters are high-efficiency filtration devices based on fluid dynamics principles, utilizing the Bernoulli Effect to achieve automated cleaning. Widely used in industrial fluid processing, this article explores their working principles, core advantages, applications, and selection guidelines to help you optimize production efficiency and reduce energy consumption.
A Bernoulli self-cleaning filter is an intelligent filtration system designed using Bernoulli’s Principle. Its core mechanism relies on the dynamic balance between fluid velocity and pressure to automatically remove impurities from the filter surface without downtime or manual intervention.
Key Components:
High-pressure-resistant filter housing
Precision filter screen (stainless steel or specialty alloys)
Hydrodynamic cleaning module (based on Bernoulli Effect)
Differential pressure sensor and intelligent control system
How Bernoulli Self-Cleaning Filters Work
Filtration Phase: Fluid enters the filter through the inlet. Impurities are captured by the filter screen, while clean fluid exits through the outlet.
Pressure Differential Trigger: When accumulated impurities increase the pressure differential, the sensor signals the control system.
Bernoulli Effect Cleaning: The system temporarily increases local fluid velocity. According to Bernoulli’s Principle (higher velocity → lower pressure), a low-pressure zone forms on the filter surface, reverse-sucking impurities into the outfall.
Cycle Reset: The system resumes normal filtration within seconds after cleaning.

Core Advantages of Bernoulli Self-Cleaning Filters
Advantage | Description |
Zero-Energy Cleaning | No external power required—cleaning relies solely on fluid kinetic energy, reducing energy consumption by 30%. |
Extended Filter Life | Non-contact cleaning minimizes screen wear, doubling lifespan compared to traditional scraper filters. |
Ultra-Low Maintenance | No mechanical scrapers or complex moving parts, cutting maintenance frequency by 60%. |
High-Precision Filtration | Supports 1-100 micron accuracy, ideal for ultra-pure fluids (e.g., semiconductors, biopharma). |
Extreme Environment Adaptability | Stable operation in high temperatures (≤200°C), high pressure (≤10MPa), and corrosive media. |

Core Advantages of Bernoulli Self-Cleaning Filters
How to Select a Bernoulli Self-Cleaning Filter?
Flow Rate & Pressure Drop: Match the model to your system’s max flow rate (m³/h) and allowable pressure drop (bar).
Filtration Accuracy: Select screen pore size (e.g., 5μm, 10μm) based on process requirements.
Material Compatibility: Choose Hastelloy for acidic media or 316L stainless steel for high-temperature environments.
Smart Features: Optional IoT modules for real-time monitoring of pressure, flow, and cleaning cycles.
Q: Does the Bernoulli filter require external energy for cleaning?
A: No! Cleaning is powered entirely by the fluid’s kinetic energy, aligning with zero-energy design principles.
Q: Can it handle high-viscosity fluids (e.g., resins, colloids)?
A: Yes, but requires custom low-flow startup modes and larger pore screens (≥50μm).
Q: Does cleaning interrupt production?
A: Never. Bernoulli cleaning is instantaneous (<2 seconds) and maintains continuous operation.
