Sintered Elements Technical Information
V73 Series In-line Filters
• Stainless steel 316 sintered
• High heat resistance and thermal stability up to 1,500°F(815°C)
• High permeability with low-pressure drop.
• Shape-stability with self-supporting structural elements
• Suitable for compression, vibration, and high impulse pressures.
• Precise filtration because pore size and distribution are exact and uniform.
• Chemical resistance against acids and caustic solutions in various ranges of pH.

Element Replacement
• The sintered elements don’t permit the contaminants in the gas and liquid to pass through the elements when they are bigger
than the pore size of micron.
• Contaminants are trapped by element pores and it results in pressure buildup.
• Contamination comes earlier when flow volume is high and media is not clean.
• The filtering elements need to be replaced for minimum pressure drop as well as system purity.
Note
: Clean filter valve components whenever the element is replaced.
