Specifications of Stainless Steel Sintered Felt

• Absolute Rating:
  The absolute ratings for Stainless Steel Sintered Felt typically range from ultra-fine levels such as 1 μm, extending up to coarser ratings like 25 μm. This range ensures versatility in filtration applications, accommodating various degrees of precision.
• Bubble Point Pressure:
  The bubble point pressure of these felts varies according to their pore size, usually falling within the range of 630 to 12300 Pa. This parameter is crucial for determining the maximum pore size and thereby the filtration capability of the felt.
• Average Air Permeability:
  The average air permeability of Stainless Steel Sintered Felt is measured in a range that generally spans from 9 to 1000 l/dm²/min. This measure indicates the ease with which air passes through the felt, a critical factor in applications requiring good airflow.
• Thickness:
  The thickness of the sintered felt is an important specification, typically ranging from 0.32 mm to 0.7 mm. This thickness is instrumental in providing adequate filtration while maintaining structural integrity.
• Weight:
  The weight of these felts is another key factor, usually lying in the range of 600 to 1200 g/m². This weight contributes to the felt’s durability and effectiveness in various filtration applications.
• Porosity:
  Porosity percentages in Stainless Steel Sintered Felt typically vary between 65% to 87%. Higher porosity indicates a greater void space in the material, which can impact filtration efficiency and dirt holding capacity.
• Dirt Holding Capacity:
  Dirt holding capacity is a vital aspect, with common values ranging from 5.47 to 33.97 mg/cm². This metric reflects the amount of particulate matter the felt can retain before requiring cleaning or replacement.
• Size:

Characteristics of Sintered Metal Fiber Felt
