The candle filter is an automated pressure filter device, mainly composed of a cylinder, filter element, filter cloth, filter aid, and other components. The cylinder and filter element are mainly made of stainless steel, carbon steel, and titanium; the filter cloth is mainly made of PP, PE, PPS, PTFE, etc. The candle filter has the characteristics of good sealing, high filtration accuracy, easy maintenance, and high degree of automation.

1. Q: What is a candle filter and how does it work?
A: A candle filter is a pressure-driven filtration system using vertical tubular filter elements. Liquid flows from outside to inside the candles, retaining solids on the surface while filtrate passes through.
2. Q: What industries commonly use candle filters?
A: Key applications include pharmaceuticals (API purification), chemicals (catalyst recovery), food/beverage (edible oil refining), and mining (slurry dewatering).
3. Q: What materials are available for filter elements?
A: Standard options include 316L stainless steel (most common), PP/PTFE for corrosion resistance, and ceramic for high-temperature applications up to 400°C.
4. Q: What filtration accuracy can be achieved?
A: Typical range is 1-100 microns. Sintered metal elements can reach 0.5μm absolute, while pleated designs offer higher flow rates at 5-10μm.
5. Q: How is cake discharge performed?
A: Our systems feature automatic gas (N2/compressed air) blowback at 4-6 bar pressure, ensuring >95% dry cake removal without manual intervention.
6. Q: Can the filter handle viscous liquids?
A: Yes. Our patented pulsating blowback technology successfully processes materials up to 50,000 cP viscosity.
7. Q: What's the maximum operating pressure?
A: Standard units withstand 10 bar at 150°C. ASME-certified designs are available for 16-25 bar applications.
8. Q: How long do filter elements last?
.A: Typical service life is 3-5 years with proper maintenance. We offer element refurbishment services to extend lifespan.
9. Q: What maintenance is required?
A: Only periodic gasket replacement (annually) and visual inspections. Our IoT-enabled models provide predictive maintenance alerts.
