An Introduction to Filters

What are Filters?

Filter acts as a device that removes components and particulates such as dirt, dust, pollen, smoke, exhaust emissions, oil from ambient air, compressor oil carryover, caustic gasses such as nitrogen oxide, and moisture from the environment. Filters are used in a diverse range of industries and environments ranging from food processing, marine and aviation, manufacturing, food and beverage packaging to medicine. Filters are essential for conditioned air and crucial for functioning many pneumatic systems and increasing component life.

Types of Pneumatic Filters                                                                        

There are four types of pneumatic filters:

  1. Pneumatic Water Separator – Helps remove water or water-borne contaminants.
  2. Pneumatic Particulate Filter – Helps remove dust and debris.
  3. Pneumatic Coalescing Filter – Helps remove oil, water, unwanted solids and liquids, and rust.
  4. Absorbing Filter – Helps remove oil from compressed air streams

Consequences of Not Using a Filter

When air is compressed up to 125 psig or about 8.6 Bar, the rate of contaminants increases up to 8 times. Without a it, the air will likely be contaminated, resulting in: 

  • Increased scrap rate
  • Damaged instruments
  • Unsafe and unpleasant environment
  • Premature wearing and scoring of surfaces
  • Rust and corrosion of pipes, tools, and equipments
