High-Strength Wedge Wire Filter Candles
Engineered for demanding backwash systems and pre-coat filtration. Our V-wire filter candles provide a perfectly uniform slot gap, exceptional structural rigidity, and a non-clogging surface for maximum uptime.
The Standard for Automatic & Pre-coat Filtration
Wedge wire filter candles are the heart of modern Candle Filters. Unlike traditional mesh or fabric sleeves, these all-metal V-wire elements are designed to handle high pressure drops and intense back-pulsing cycles without deformation.
They are particularly effective for pre-coat filtration (using diatomaceous earth or perlite) in the chemical, beverage, and oil industries, providing a stable foundation for the filter cake.

Key Benefits
Superior Backwashing
The V-profile wire ensures that particles only touch two points on the slot, making them easy to dislodge during reverse flow.
High Collapse Strength
Reinforced internal support rods allow the candle to withstand high differential pressures (up to 20-50 bar).
Reusable & Sustainable
Unlike disposable cartridges, wedge wire candles are permanent elements that can be cleaned and reused for years.
Diverse Configurations
Edible Oil: Clarification and winterization of oils using pre-coat technology.
Brewing & Beverage: Beer and wine filtration for crystal clear results.
Chemical Industry: Catalyst recovery and fine chemical separation.
Water Treatment: Automatic self-cleaning filters for industrial cooling water.
Applications
Flow Out-to-In (Standard): Solids collect on the outer surface.
Flow In-to-Out: For specific internal collection needs.
Reinforced Type: Extra support rods for high-viscosity fluids.
Sanitary Finish: Electropolished surface for food and pharma use.
Frequently Asked Questions
Yes, wedge wire candles are excellent upgrades. They offer better slot consistency and much longer service life compared to mesh or fabric.
We can achieve slots as fine as 20 microns (0.02mm), which is ideal for many fine chemical and beverage applications.
We use a proprietary resistance welding process that fuses the V-wire to the support rods at every intersection, creating a single rigid structure.
