Anping County Boli Hardware Wiremesh Products Factory, established in 1998, is a professional manufacturer specializing in filtration solutions. With an annual export value of US$5-10 million and markets spanning North America, Europe, Asia, and Oceania, we bring decades of expertise to every product. Our Automatic Backwash Stainless Steel Wedge Filter with Johnson Vee Wire Screen is designed for efficient, low-maintenance solid-liquid separation in demanding industrial environments. Powered by 220V and rated IP65 waterproof, this filter ensures reliable operation even in wet or dusty conditions.
The core of this filter is the Johnson Vee Wire screen, a wedge-wire construction that provides precise filtration slots, high mechanical strength, and excellent backwash efficiency. The automatic backwash mechanism cleans the screen without interrupting flow, reducing downtime and manual labor. The stainless steel material offers corrosion resistance and long service life. Below are key technical parameters:
| Parameter | Value |
| Filtration Precision | 50-500 micron (customizable) |
| Working Pressure | Up to 10 bar |
| Voltage | 220V AC, 50/60Hz |
| Protection Rating | IP65 (waterproof, dustproof) |
| Screen Material | Stainless Steel 304/316 |
| Connection Type | Flange or threaded (optional) |
| Backwash Mode | Automatic, pressure differential or time-based |
Product Features and Benefits:
- Automatic Backwash: Built-in control system triggers backwash when pressure drop exceeds set point or at preset intervals, no manual cleaning required.
- Johnson Vee Wire Screen: Continuous slot opening ensures uniform filtration, high flow capacity, and easy backwash cleaning. The wedge wire profile reduces clogging.
- Stainless Steel Construction: Resistant to corrosion, rust, and high temperatures, suitable for water, oil, chemicals, and food processing.
- IP65 Waterproof: Enclosure protects electrical components from water jets and dust, allowing outdoor or wet-area installation.
- Low Maintenance: Self-cleaning mechanism reduces filter replacement frequency and labor costs.
- Customizable Options: Filtration precision, connection size, flange standards, and motor voltage can be tailored to your application.
Typical Applications:
- Industrial water treatment (cooling water, process water)
- Oil & gas (produced water, crude oil filtration)
- Chemical processing (liquid-solid separation)
- Food & beverage (juice, beer, wine filtration)
- Wastewater treatment (primary and tertiary filtration)
- Irrigation systems (agricultural water filtration)

Frequently Asked Questions (FAQ):
Q1: What is the working principle of the automatic backwash filter?
A: The filter operates continuously. When the differential pressure across the screen reaches a preset value, the control system activates a backwash cycle. A motor-driven mechanism rotates a suction scanner or uses reverse flow to clean the wedge wire screen, flushing debris out through a drain valve. The process takes only a few seconds and does not interrupt main flow.
Q2: What media can be filtered with this wedge wire screen?
A: It is suitable for liquids with suspended solids, such as water, wastewater, oil, chemicals, and food liquids. The stainless steel construction can handle mild corrosive fluids; for highly corrosive media, SS316 or other alloys are available.
Q3: What filtration precision range is available?
A: Standard precision ranges from 50 to 500 microns (0.05mm to 0.5mm). Custom slot sizes down to 20 microns or up to 1000 microns can be produced upon request.
Q4: Does the filter require an external power source?
A: Yes, the backwash motor and control box require 220V AC power supply. The IP65 rating ensures the electrical components are protected from water and dust.
Q5: How often does the automatic backwash occur?
A: The backwash frequency depends on the solid load and flow rate. Typically, it can be set based on time intervals (e.g., every 2-8 hours) or triggered by differential pressure (e.g., 0.5 bar difference). The controller is programmable.
Q6: Can I customize the connection size and flange standard?
A: Yes, we offer various flange standards (ANSI, DIN, JIS) and pipe sizes (2"/4"/6"/8"/10" etc.). Threaded connections are also available for smaller diameters.
Q7: What is the typical lifespan of the wedge wire screen?
A: With proper operation and maintenance, the screen can last 5-10 years or longer, depending on the fluid characteristics and abrasiveness. Stainless steel resists wear and corrosion.
Q8: What warranty and after-sales support do you provide?
A: We offer a 12-month warranty against manufacturing defects. Technical support is available via email or phone, and we can provide spare parts such as screens, seals, and motors.
