This Must Be What You Care About Most
In environments with high corrosion, heavy loads, and continuous operation, only two things truly matter:
Reliable equipment performance
Lower maintenance costs
This is exactly where wedge wire filter elements deliver their value.
With years of industry experience, SINFT has developed a complete design and manufacturing system for wedge wire products. We are especially strong in wedge wire candle filters, providing high-reliability solutions for automatic backwashing filtration systems — fully compatible with leading international brands.
- • High mechanical strength — built to withstand pressure shocks
- • Continuous backwashing — resists clogging and deformation
- • Extended service life — significantly reduces operating costs
- • Engineered for harsh applications: desalination, steel plants, chemical processing, power generation, and more
For a more stable and efficient system, SINFT delivers high-quality wedge wire filter elements and matching components — an integrated solution for demanding filtration operations.
The SINFT Advantage
• Fully compatible with mainstream filters
SINFT delivers proven manufacturing expertise and extensive industry experience, specializing in wedge wire candle filters for automatic backwashing systems. Our filters are fully compatible with major brands such as BOLL, HYDAC, and MAHLE — offering complete model coverage, excellent fit, and consistently reliable performance.
• Long-life filter media
Made from stainless steel wedge wire or metal fiber materials, providing superior pressure and temperature resistance. The elements can be repeatedly cleaned and are especially suitable for harsh environments with high humidity or corrosive media. (Material inspection reports available.)
• Bidirectional automatic backwash design
The filter element is mounted inside the housing, where a vertical reverse-flow path combined with a top-mounted rotary throttling mechanism enables efficient online cleaning. This design effectively removes accumulated contaminants without disassembly or replacement, significantly reducing maintenance costs.
• Wedge wire elements offer 25–150 μm slot sizes and can serve as filtration media or support layers. Slot size, structure, length, material, and filtration area can be customized to suit specific operating conditions.
• Manufacturing & Quality Control
Continuous resistance welding
Slot size inspection via projector
Bubble point & flow testing
Spectrometer material verification
Dimensional & structural inspection
Welding procedure qualification (WPS / WQR available)
Each wedge wire product is inspected to ensure slot accuracy, structural integrity, and long-term reliability.
