How to choose a precision compressed air filter

  • When you pick an air filter that squeezes air, remember these things:


    How big the particles need to be filtered.

    There are filters that can remove small bits from 5 to 40 microns.

    There are special filters that can remove really tiny particles, which are smaller than a certain size called 1 micron. These filters are mostly used in places where medicines and food are made.

    When water or other fluids flow through pipes, they experience resistance which reduces the pressure. This reduction in pressure is called pressure loss or pressure drop.

    These can move up to 1,700 big air units in one hour.

    To find the right size, figure out how much pressure the filter can handle at most.


    Look at the graph provided by the manufacturer that shows how much fluid flows at different pressures.

    Try to prevent the pressure from dropping more than 5 psi for best results.


    Temperature is how hot or cold something is. It is usually measured with a thermometer in units called degrees Celsius (or sometimes Fahrenheit). High temperatures mean something is hot, and low temperatures mean something is cold. People and animals can feel temperature changes and may need to change their behavior or clothing to stay comfortable. Different materials can also affect temperature, for example, metal might be colder or hotter than wood because it conducts heat differently. Temperature is an important factor in many areas of science and daily life.

    What temperature does the compressed air filter work at?

    You can get really good filters that work well in really hot places (above 450°C).


    Environmental standards are rules about how people and companies should take care of the environment to prevent harm to nature. These rules can help protect the air, water and land from pollution, and preserve wildlife and natural resources for future generations.

    Compressed air filters follow ISO 8573 rules. This makes sure the compressed air is clean from solid particles, water, and oil, no matter where they are in the system.

    This rule tells us about bad stuff that can be in the air we use for machines. It also talks about other rules that say how to test or set rules about how clean the air needs to be.


    The ISO 8573-1:2010 rule states that there are bad gases and tiny living things that can contaminate things.
