VITHY® Titanium Powder Sintered Cartridge is made from titanium powder through high-temperature sintering. It does not have any media shedding and does not introduce any chemical contaminants. It can withstand repeated high-temperature sterilization or continuous high-temperature use. The titanium rod filter cartridge can withstand a maximum temperature of 280°C (in a wet state) and can withstand pressure changes or impacts. It has high fatigue strength, excellent chemical compatibility, corrosion resistance, and is suitable for filtering acids, alkalis, and organic solvents. The titanium material can withstand strong acids and can be cleaned and reused. With outstanding performance, it can be used for both suction filtration and pressure filtration.
The cartridge is available with end caps such as M20, M30, 222 (insertion type), 226 (clamp type), flat, DN15, and DN20 (thread), while special end caps can be customized.

The cartridge can be made into both automatic filter and manual filter.
1. Automatic filter:
2. Manual filter:
The filter housing is made of high-quality stainless steel 304 or 316L, with both inner and outer surfaces being mirror polished. It is equipped with a single or multiple titanium rod cartridge, which gives it the characteristics of high temperature resistance, corrosion resistance, high filtration precision (up to 0.22 um), non-toxicity, no particle shedding, no absorption of medication components, no contamination of the original solution, and long service life (typically 5-10 years) - all of which meet the requirements of food hygiene and pharmaceutical GMP.
Furthermore, it has the advantages of small size, light weight, easy use, large filtration area, low blockage rate, fast filtration speed, no pollution, good thermal stability, and excellent chemical stability. Microfiltration filters are capable of removing a majority of particles, making them widely used for precision filtration and sterilization.

It is mainly used in acid, alkali, and organic solvent filtration, etc. in industries such as pharmaceuticals, food, chemicals, biotechnology, and petrochemicals.
1. Corrosion Resistance
Titanium metal is an inert metal with excellent corrosion resistance. A titanium rod cartridge made of titanium metal can be used for filtration in strong alkali and strong acid materials. It is widely utilized in the chemical industry and the filtration process of organic solvent enzyme production in the pharmaceutical industry. Titanium cartridge is particularly useful in cases where organic solvents like acetone, ethanol, butanone, etc. are used. In such situations, polymer filter cartridges like PE and PP cartridges are prone to dissolution by these organic solvents. On the other hand, titanium rods are quite stable in organic solvents and thus find extensive use.
Corrosion resistance grade of titanium filter can be categorized as follows:
Class A: Fully corrosion-resistant with a corrosion rate below 0.127mm/year. Can be used.
Class B: Relatively corrosion-resistant with a corrosion rate between 0.127-1.27mm/year. Can be used.
Class C: Not corrosion-resistant with a corrosion rate exceeding 1.27mm/year. Cannot be used.

2. High Temperature Resistance
Titanium filter can withstand high temperatures up to 300°C, which is unmatched by other filter cartridges. This feature is widely used in high-temperature operating environments. However, filter cartridges made of high-polymer materials have poor temperature resistance, generally not exceeding 50°C. When the temperature exceeds 50°C, their support and filter membrane will undergo changes, resulting in significant deviations in filtration accuracy. Even PTFE filter cartridges, when used in operating environments with an external pressure of 0.2 MPa and temperatures above 120°C, will deform and age over time. On the other hand, titanium rod filter cartridges can be used long-term in such environments, with no changes to its micro-pores or appearance.
Widely used for the filtration of high-temperature liquids and steam filtration (such as in steam filtration during fermentation processes).
3. Superb Mechanical Performance (High strength)
Titanium rod filter cartridges have superb mechanical performance, withstanding an external pressure of 10 kg and an internal pressure destruction force of 6 kg (tested without joints). Therefore, titanium rod filters can be used in processes that involve high pressure and fast filtration. Other high polymer filter cartridges undergo changes in microporous aperture or even breakage when subjected to external pressures exceeding 0.5 MPa.
Applications: Chemical fiber manufacturing industry, pharmaceutical industry, compressed air filtration, deep underwater aeration, aeration and foaming of coagulants, etc.
Excellent mechanical performance (as shown in the figure), sturdy and lightweight (specific gravity of 4.51 g/cm3).

4. Excellent Regeneration Effect
The titanium rod filter cartridge has good regeneration effects. Due to its good corrosion resistance, high temperature resistance, and high strength performance, there are two methods for regeneration: physical regeneration and chemical regeneration.
Physical regeneration methods:
(1) Pure water backflushing (2) Steam blowing (3) Ultrasonic cleaning
Chemical regeneration methods:
(1) Alkaline washing (2) Acid washing
Among these methods, chemical regeneration and ultrasonic cleaning methods are the best, with low decrease in filtration efficiency. If used or cleaned according to normal operation, the service life can be greatly extended. Due to the good regeneration treatment effect of titanium rods, they have been widely used in the filtration of viscous liquids.
