What is FiltEdge's Candle Filter Housing?
FiltEdge’s Candle Filter Housing is the centerpiece of your filtration system, which is the core component that withstands pressure, feeds slurry, filters and separates, and collects residue, etc. It is also the core of the entire filtration system. It is also the centerpiece of your filtration system. From the time your filter material is put into the Candle Filter Housing, it is continuously filtered and clarified in the same pressure vessel, and the residue is retained and collected. It is the cornerstone to ensure that your production process can run continuously and stably for a long period of time.

FiltEdge’s Candle Filter Housing Addresses Leakage Risks
Have you ever worried about that tiny leak at the moment of pressure buildup in a high-pressure differential filtration process? For high-value raw materials or toxic media, even a small leak that is not visible to the naked eye can expose you to environmental contamination, employee health risks, or even force an entire production line to shut down.
At FiltEdge, we help you seal off the risk with four levels of protection:
- Eliminate weld hazards. We understand your need for structural strength. That’s why FiltEdge’s candle filter housings are not only made of high-strength materials such as 316L, but are also fully welded to minimize the number of welds. Every weld is 100% non-destructive testing to ensure that leaks caused by welding defects are avoided at the source.
- Top quality sealing material, suitable for your extreme working conditions. Whether your process is corrosive or high temperature, you can choose the most suitable FFKM, Viton or PTFE seals on the candle filter housing. With our double-layer sealing structure, you can get a long-lasting and stable sealing performance even under severe pressure fluctuations.
- Intelligent monitoring system, be your “second pair of eyes”. You no longer need to keep a close eye on the pressure gauge. Our candle filter housing intelligent system will automatically adjust the pressure and smooth out erratic fluctuations. If any abnormality occurs, the system will alert you immediately, allowing you to intervene before an accident occurs and to resolve the crisis.
- Structural reinforcement against flange deformation. In response to your concern about flange loosening, we adopt thickened flanges and high-strength O-rings in candle filter housing. Together with the metal ring sealing technology, even if the equipment is subjected to thermal expansion and contraction or vibration for a long period of time, it can still help you guard the last line of defense and ensure that no water leaks from the interface.
How FiltEdge’s Candle Filter Housing Tackles Contamination？
In pharmaceutical or food processing, there’s nothing you worry about more than the remnants of one batch hiding in a “dead end” and ruining the next batch of expensive finished product. Cross-contamination from incomplete cleaning is not only a recipe for a product recall, it’s also a nightmare when faced with a compliance audit.
How can FiltEdge help you stay clean?
- Ra 0.4μm Mirror Grade Protection: Not just for brightness, but for safety. We offer a high standard of electropolished interior surfaces for our candle filter housings, with a surface smoothness of up to Ra 0.4μm or less. This means that you can significantly reduce the amount of cleaning fluid you need to use and significantly reduce the probability of microbial growth.
- Truly CIP-automated cleaning: You no longer have to deal with tedious disassembly. Our candle filter housing systems are natively adapted to your CIP (Cleaning In Place) process, with fully automated cycles starting at the touch of a button. This not only avoids the fluctuation caused by incomplete manual cleaning, but also allows your equipment to return to fighting condition in the shortest possible time, keeping your production rhythm.
- Completely eliminate dead corners: For your most worried about valve ports, joints and other hidden trouble locations, we have adopted a unique flow optimization design in the candle filter housing. This “no dead space” construction ensures that the cleaning solution covers every inch of the metal surface, completely removing hidden buildup and helping you pass the toughest industry compliance audits with ease.
- 6-Petal Plum Blossom Cartridge: Instead of the traditional round shape, we’ve configured our candle filter housing with a 6-petal plum blossom cartridge. During the self-cleaning phase of the blowback, the unique “pulse pop” of this construction quickly dislodges the filter cake like a shell. This means that your filter cartridge is no longer gummed up with sticky material and is as efficient as a new unit every time you start up.
Candle Filter Housing for High Viscosity and High Solid Content Slurry
In the face of high solid content and high viscosity slurry, traditional filters will give you the biggest headache, such as “the filter cake sticks” and “the filter cartridge can’t be washed”. Once the filter element is stuck, it not only means frequent downtime for dismantling and cleaning, but also the loss of raw materials, and even affects your reputation in the market due to the delay of delivery.
At FiltEdge, we’ve got the right combination of tools for difficult pastes:
- Large capacity design: We will extend the filtration area of Candle Filter Housing up to 150 square meters according to your flow demand. By increasing the physical area, we can directly help you to extend the single filtration cycle and reduce the frequency of cleaning fundamentally.
- “Residue Filtration”: We not only equip your Candle Filter Housing with 0.1μm high-precision filter element, but also introduce the “Pre-coating Filtration” technology. Self-filtration through the formation of a cake layer not only improves the purity of your product, but more importantly, it changes the structure of the cake, making subsequent blowback stripping a breeze.
- 6-Petal Plum Blossom Design: Difficult to strip the filter cake? Our Candle Filter Housing utilizes a 6-part plum-shaped cartridge, which creates a slight deformation at the moment of blowback, like an umbrella being retracted, to “pop” the sticky filter cake. This structure can greatly reduce the risk of deep clogging of the cartridge and extend the life of your consumables.
- Pre-filtration: For very high content slurries, we recommend that you have a FiltEdge automatic backwash or bag filter on the front end. By intercepting large particles at the front end, the load on the Candle Filter Housing at the back end will be significantly reduced, ensuring that your core line remains efficient.
- True Automation: Our Candle Filter Housing system incorporates one-touch backwashing and self-cleaning. No longer do you need to have someone on the machine at all times, the system will automatically maintain high throughput, returning valuable production time to your shop floor.
How FiltEdge’s Candle Filter Housing Tackles Temperature Instability？
Are you facing frequent temperature swings in post-crystallization filtration or solvent system filtration? This dramatic thermal expansion and contraction is the “invisible killer” of your equipment. Not only does it accelerate fatigue damage in welds, it can even cause the polish to crack and peel off. If your equipment fails, you not only face costly downtime for repairs, but also the possibility of massive contamination from tiny metal shavings or weld cracks that can undo your compliance efforts.
FiltEdge’s thermal stress protection system keeps you safe:
- Optimize high-performance materials to combat thermal expansion and contraction. Considering the extreme temperatures you are exposed to, we insist on using high-quality 316L stainless steel for our candle filter housings. The excellent thermal stability of this material ensures that your filter will maintain its structural strength and will not be easily deformed during frequent temperature cycles.
- “High temperature insurance” at the sealing level. You no longer need to worry about the seals of the candle filter housing becoming brittle or failing in hot solvents. We provide you with the top sealing configurations such as FFKM and PTFE, which can still maintain excellent elasticity under high temperature fluctuations and help you seal every potential leakage point.
- Micron-level polishing to guard the life of the weld. In order to minimize the “tearing” effect of thermal stress on the welded joints of the candle filter housing, we will polish the inner and outer walls of your equipment with high precision. This not only optimizes surface smoothness and prevents material accumulation, but also effectively buffers the physical impact of thermal expansion and contraction, extending the service life of the equipment.
- Redundant reinforcement design, rejecting structural cracks. For the weak areas of flange connection and welding that you are most worried about, we have specially thickened and reinforced the candle filter housing. This “redundant design” ensures that your equipment will not loosen or stress crack due to thermal fatigue even during long periods of high temperature and high pressure cycling.
- Deep annealing process to completely eliminate “internal damage”. Every FiltEdge candle filter housing will undergo a rigorous annealing process before leaving the factory to eliminate the residual internal stresses generated during the machining process. This dramatically improves the toughness of the material, making your equipment feel like it’s made of steel and ready to take on every thermal cycle.

Since the filter cartridge is a whole vertical hanging inside the candle filter housing and cannot be folded, so when you check and maintain the equipment and need to pull out the filter cartridge, you need to consider whether the height space between the top of the filter and the plant can satisfy the length of the filter cartridge (usually between 1.6m and 2.6m), so that you can use the crane or manually carry out the maintenance.
Yes, this is possible. Considering that some customers are renovating old plants or upgrading production lines, we at FiltEdge support customized Inlet and Outlet orientations for the candle filter housing. We will design the candle filter housing 180° side to side, 90° vertical or side to side, depending on your requirements for the inlet and outlet. If you have a requirement for the height of the bottom outlet from the floor, we can also design it precisely for you.
No. ф60 and ф86 are the most common industrial standard sizes of Candle Filter Housing, which you can get easily in the market. If you have extreme requirements for the balance of the flow field, we can customize non-standard diameters for you.
FiltEdge’s candle filter housing can realize intelligent control for you. Once the turbidimeter detects an abnormality in the filtrate clarity, the PLC control system will immediately switch to the recirculation filtration mode for you and send an early warning to your console simultaneously.
FiltEdge’s candle filter housing is equipped with an intelligent differential pressure monitoring system, which triggers a back-purging program before bridging occurs, blowing off the soon-to-be-constructed filter cake, thus eliminating the risk of sludge jamming in your equipment.
You don’t need to have such concern. The cartridges in our Candle Filter Housing have a plum tube structure that provides you with excellent rigid support. Whether it is a filter aid such as diatomaceous earth, perlite or activated carbon, they form a uniform and stable pre-coating on the surface of the filter cartridge and will not damage the structure of your equipment.
Yes, you can. We can configure all-welded Wedge Wire cartridges for rough filtration or catalyst recovery applications that do not require filter cloth. In this configuration, your Candle Filter Housing is virtually “maintenance free” for life, with automatic backwashing to restore flow and no need to purchase and replace filter media.
The biggest advantage of the Candle Filter Housing over the Plate & Frame Filter Press is that it is “fully automated and fully enclosed”. It not only solves the problem of “dripping and leaking” that is common in traditional plate and frame machines, but also protects your workers from chemical and toxic substances, and helps your process easily meet compliance requirements.
The air consumption when driving the candle filter housings is very small. This is because the blowback is an instantaneous pulse action and does not require constant air consumption. If you don’t have a stable compressed air source at your production site, we can equip your candle filter housing with an air compressor to ensure that your equipment has sufficient power for slagging.
We can provide upgrading service for your old candle filter housing, provided that the housing of your old equipment is intact. We customize a full set of internals (e.g., dispensing tubes, cartridge holders) to give your old filter a new lease of life at the lowest possible cost.
Yes, of course. Every Candle Filter Housing delivered to your site comes with a detailed O&M Manual in English and Chinese. The manual contains the exploded views, parts lists, PLC logic, and troubleshooting procedures you need to get your operators up and running.
We offer a fast 24/7 response. Our engineers can guide you remotely if you have a question about software logic, or if it’s a hardware problem, our warehouses in the U.S. and China will ship you spare parts as quickly as possible. This model is designed to minimize your downtime losses and keep your production line running smoothly.
