High Pressure Filters
High Pressure Technologies offers a comprehensive range of high pressure filters. These high pressure filters (Suitable for Gas or Liquid) are typically used to protect downstream components and instrumentation from contamination levels beyond the recommended cleanliness target. They help in protecting these important parts or components from destructive failure.High pressure filters styles consist of Super-Mini Tee-Type Filters, Mini In-Line Filters, In-Line Filters, Tee-Type Filters, Multi-Use Compact In-Line Filters (replaceable element) and Spin-On Filters. High pressure filters can support pressures varying from 6,000 psi, 10,000 psi, 20,000 psi, 30,000 psi & 40,000 psi depending on which type of filter is used.

Sintered Filters Specifications
Sintered Bronze Filter Media is a very important addition to filtration technology. It is recognized the world over for its superior and dependable filtration characteristics.
Sintered bronze filter part is created from spherical bronze powder of closely controlled particle size to convey a rigid porous structure of uniform pore dimensions.
Unlike other filtering media, sintered bronze is self-supporting. Being metallic, it is resistant to impact.
Important characteristics of Sintered Bronze Filter
The structure of materials based on individual particles sintered together offers a high porosity material with its most important property, PERMEABILITY. The labyrinth pore structure of SFTPL elements allows:
Filtering of solid particles from gases, liquids and molten plastics.
Separation of liquids from gases,
Damping, throttling,
Drying and Moistening of gases
Uniform distribution of air and gas over large areas:
--- for dispersion of gases in liquids
--- for transportation, drying or moistening of powder or granulates
--- for supporting of moving parts (aerostatic and hydrostatic bearings).
The coefficient of permeability of KPMI sintered bronze elements can be calculated as:
Where,
=Coefficient of permeability of a given grade in Darcy (* 1 darcy=10-8)cm2
Q =Flow of fluid through sintered bronze element in cc/sec.
L =Thickness of filter element in cm
n =Viscosity of fluid in poise
p= Pressure drop across element in dynes/cm2
Design
Filter and porous components are made of spherical bronze powder. It could be offered by small wall thickness and high length, made by gravity sintering process. That can be available in different shape as diameter from 2 to 250 mm, and length from 2 to 1000 mm. Sintered bronze porous material with the thread integrated in the filter.
