Solids removal filters

What is a solids removal filter?

A solids removal filter (also known as a pre-filter) is often placed before the coalescer filter in filtration systems. The solids removal filter is specifically designed to remove solid particles, such as dirt, dust, rust, sand, or other mechanical contaminants, from liquid or gas streams. By removing solid particles, it protects the coalescer filter from clogging or damage. This extends the life of the coalescer filter and increases the efficiency of the entire filtration system.

How does a solids removal filter work?

• The incoming liquid or gas first flows through the solids removal filter.
• Solid particles, depending on the filter fineness, are captured and removed.
• The cleaned stream, now free of solid particles, continues to the coalescer filter, where the coalescing process can take place without obstruction.

Applications of a solids removal filter

• Oil and gas industry, where solid particles are removed from gas or liquid before it enters the coalescer.
• Fuel treatment systems, where solid particles such as dirt or rust are removed from fuel streams to protect the system.
• Chemical and petrochemical industry, where both solid and liquid contaminants are present in the stream.
