Product Introduction

The Sintered Stainless Steel Porous Metal Filter Tube is created from irregularly-shaped stainless steel powder, typically AISI 316L. The powder is compressed into a mold, then sintered at high temperatures to form a porous tube with exceptional resistance to high temperatures, corrosion, and mechanical strain.

The pore size of the filter can be determined by the choice of powder and the applied pressure during compression. The shape, size, and distribution of the powder impact the final properties of the filter.


At filtration accuracies of 70�µm or finer, particle chipping can be an issue with some filters. However, our sintered metal tube avoids this problem thanks to our advanced vacuum sintering equipment and skilled production staff.

Furthermore, each sintered metal tube undergoes rigorous testing with bubble point and air permeability tests according to ISO 4003 and ISO 4022, respectively. This ensures that our filters are of the highest quality and meet the needs of every customer.

Porous sintered metal filters are constructed from interconnected networks of uniformly distributed pores, creating intricate pathways that effectively capture solid particles present in gas or liquid flow streams. These filters are renowned for their exceptional mechanical strength and serve as outstanding depth filters. Type 316L stainless steel, known for its robustness, can endure temperatures up to 750�°F (399�°C) in oxidizing environments and 900�°F (482�°C) in reducing environments.

The production of sintered metal filters involves employing 316L stainless steel powder. The manufacturing process entails the uniaxial compaction of powder within a rigid tool possessing the inverse shape of the desired part, followed by sintering. By adjusting the compaction pressure and/or particle size of the powder, the pore size of the filter can be precisely controlled.

Therefore, a class of fasteners that already have national standards is called standard fasteners, or simply standard ones.

TOPTITECH stainless steel carbonation stones, not truly stones, are predominantly crafted from porous stainless steel 316L, also known as 'Air Stones'. These stones are commonly employed to aerate wort before fermentation, ensuring a robust start to the fermentation process. Constructed from top-tier food-grade stainless steel material 316L, TOPTITECH carbonation stones boast healthiness, practicality, durability, high-temperature resistance, and corrosion resistance. They offer easy cleaning and remain intact in beer or wort post-use.

These stainless steel carbonation stones from TOPTITECH are well-suited for force carbonating beer, making them an excellent choice for kegged beer carbonation or as an aeration stone pre-fermentation. Professionals use stainless steel carbonation stones to carbonate beverages such as beer, champagne, or sparkling meads with carbon dioxide. The micron stainless steel carbonating stone accelerates beer carbonation, producing a long-lasting head due to the creation of smaller bubbles. It rapidly infuses beer/soda water with CO2 or O2 by passing the gas through millions of tiny stone pores, effectively dissolving it into the liquid, enriching the mouthfeel of your beer or soda water.

Yeast thrives in an environment devoid of bacterial competition, ensuring both quality fermentation and a bacteria-free end product.

2. Enhanced Carbonation Control: Stainless steel filters provide brewers with precise control over the carbonation levels in beer, ensuring consistent quality and desired effervescence.

3. Enhanced Efficiency: Stainless steel filters used as carbonation stones offer enhanced efficiency in the carbonation process compared to traditional methods. The micro-pores in the stainless steel allow for a finer dispersion of carbon dioxide bubbles, resulting in more effective and controlled carbonation.

4. Consistent Carbonation: One of the key benefits of using stainless steel filters as carbonation stones is the ability to achieve consistent carbonation levels in every batch of beer produced. This consistency is crucial for maintaining the desired flavor profile and mouthfeel of the beer.
