What is the Industrial Candle Filter?
FiltEdge’s Industrial Candle Filter is a highly efficient, fully enclosed pressure filtration system with no moving parts, and is the most central and critical component of the entire filtration system. It performs all key functions independently, from the feeding of the slurry, to the clarification of the liquid, to the final drying and discharging of the filter residue. It is not just a simple filtration equipment, but also the core lifeline to control the quality of your final product.
Why Choose FiltEdge's Industrial Candle Filter?
Industrial candle filters perform solid-liquid separation within a filtration system. Selection must account for slurry properties, operating conditions, containment and maintenance requirements. FiltEdge coordinates design and supply with manufacturing support in China; applicable documentation and suitability must be confirmed for the selected equipment.
FiltEdge Supply Industrial Candle Filter Types
FiltEdge offers different types of industrial candle filters to better suit your production process. In case of extreme conditions, we can deeply customize the filter according to your needs.
It significantly releases labor cost and realizes 24/7 uninterrupted production. Designed for stable continuous high flow conditions, the fully automatic blowback and sludge removal keeps the filtration system at consistently optimal performance entirely without human intervention.
The ultimate sealing to protect your safety and compliance. Fully Enclosed Pressure Structure completely eliminates the risk of volatilization, dripping and hazardous material contact, which is the first choice for leakage prevention in pharmaceutical, strong corrosion and fine chemical industries.
It meets the stringent requirements of GMP, controlling purity of every gram of material for you. Specifically designed for API and pharmaceutical intermediates, the machine has no dead space and zero residue structure, which realizes 100% filter cake recovery and eliminates the risk of cross contamination. It is ideal choice for your pursuit of high compliance and ultimate yield.
Stainless steel material options include the stated 304, 316L and 2205 grades. Confirm material compatibility, welding requirements and surface finish against the actual chemical and operating conditions.
Easy to handle high-viscosity slurry, greatly enhance the subsequent process efficiency. It is specially optimized for 1%-20% high solid content materials, and through the efficient thickening cycle technology, it can quickly push the originally difficult to handle slurry to the best separation state. It is the “efficiency booster” for doubling the production capacity of lithium-ion and new energy material production lines.
It challenges the limit of clarification and guards the last gate of product quality. Equipped with an ultra-high-precision filter element structure, the filter stably realizes ultra-precision filtration at the 0.1μm level. Even micron-sized suspended impurities can be precisely retained, ensuring that your final product has the ultimate clarity and helping your product stand out in the high-end market.
The ultimate in filter press drying, minimizing material loss and transportation costs. The unique backblast discharge system produces an extremely dry cake with a moisture content of <20%. No additional drying process is required for direct recovery or rapid disposal of solids, making your resource cycle more efficient and economical.
It is designed for large-scale industrial production and can easily handle a large number of filtration tasks. Adopting compact multi-tube bundle structure, it provides huge filtration area in a very small footprint. Designed for petrochemical, large-scale water treatment and other high-flow, high-continuity conditions, to ensure that your plant still has excellent system stability under continuous full load operation.
Features of Industrial Candle Filter
The superior performance of FiltEdge’s Industrial Candle Filter produces clarified filtrates, dry recoveries, increases your productivity and reduces your operating costs.
It is designed for fully enclosed pressure operation. It directly cuts off the volatilization path of flammable and toxic materials, eliminates the risk of dripping from the source, and helps your workshop pass the environmental safety audit easily.
There are no rotors, motors or other moving parts inside the system. This “static operation” means virtually zero wear and tear, saving you from costly seal replacements and downtime.
It is available with a wide range of high-performance microporous filter media with an accuracy of up to 0.1μm. This allows you to filter even the finest suspended contaminants, providing laboratory-grade clarification for your downstream processes.
It utilizes a highly efficient blowback press to produce a very dry cake with less than 20% moisture content. Recycling without secondary drying significantly reduces the hidden costs of solid waste disposal and transportation.
From feeding, filtration, washing, drying to discharging, the whole process is PLC controlled, and there is no need for manual attention after one key start, which not only saves manpower, but also avoids the batch instability caused by manual operation.
From 316L, Hastelloy to PTFE lining, we can customize according to your material pH. Whether it’s strong acid corrosion or high purity grade requirements, we have the proven material library to back it up.
It specializes in 1%-20% high-solids applications. With its unique thickening cycle design, it can rapidly increase the consistency of slurry in a small space, which is the key to “doubling the capacity” of subsequent centrifugal equipment.
It fully supports fully automated in-situ cleaning. No need to dismantle the machine for maintenance, it can be thoroughly cleaned during batch changeover, which is a mandatory safeguard against cross-contamination in API and sterile pharma.
6-Segment Petal-Shaped Design's Industrial Candle Filter
Can’t get the cake out? You’re not using the right cartridge. FiltEdge’s Industrial Candle Filter has a secret weapon: a 6-segment petal-shaped filter element. At the moment of blowback, the filter cartridge will pop open like a flower petal, and it will shake off all the sticky filter cake. With no hang-ups and no clogging, your filter cloth will naturally last longer than others.
Skid Block Modular Industrial Candle Filter
Don’t waste your time with installation. FiltEdge has taken the complexity of the Industrial Candle Filter and made it a complete package, ready to use out of the box.

Shipping schedules for customized housings, skid-mounted systems and consumables depend on specifications, stock availability, quantity and production scheduling. Confirm the delivery and shipment terms in the quotation; next-day shipment is not guaranteed.
Absolutely.
We offer PTFE-lined candle filters and Hastelloy filter housings specifically designed for strong acid or hazardous chemical filtration to ensure that your filters are corrosion resistant.
The lifespan of an Industrial Candle Filter is primarily based on a combination of material of manufacture, usage and frequency of maintenance. If you maintain it properly, your filter can last up to 10 years.
Automatic Self-cleaning Filter relies on the cartridge to separate the slurry into mother liquor and filter residue, the filter residue adsorbed on the surface of the cartridge, and so on, when the pressure reaches a certain level, the backblowing device will be activated automatically, through the backblowing technology will be stripped of the filter residue discharged to achieve the filter element of the automatic cleaning demobilization, and automatically enter the next filtration. Automatically enter the next filtration. In the operation process you do not need any manual intervention operation, to give you a continuous high flow of slurry for full filtration.
Our filters use high-precision cartridges, combined with dregs filtration technology, the precision can be increased to 0.1μm such as high-precision, it depends on what precision is suitable for your actual filtration media, and we configure the appropriate precision to ensure that your final product is of high quality.
FiltEdge’s candle filters are usually vertical filters with a small footprint that requires upward space. You can tell us the condition of your plant, and we will design the layout according to your actual space.
Safety interlocks are standard on our filters. All actuators of the system are “normally closed” or with “fail-safe” position. Once your filter encounters a power failure, its valves will automatically close, locking the material in the tank and preventing it from getting out, improving your production safety.
