Air Compressor Oil Water Separator Moisture Filter

G series precision filters provide users with high-quality compressed air filtration, especially used in laser cutting, bottle blowing, advanced spraying, food, electronics, petrochemical, and other industries. By installing DFG series precision filters, compressor air pollutants (such as oil, water, dust, etc.) can be effectively removed.

H1:Do I Need a Filter for My Air Compressor?

Why You Need an Oil Water Separator Moisture Filter for Your Air Compressor

Compressed air often contains moisture, oil vapors, and particulates, which can damage pneumatic tools, reduce efficiency, and contaminate your product. That’s why an Air Compressor Oil Water Separator Moisture Filter is essential for any compressed air system.

Without proper filtration:

  • Moisture causes rust and corrosion

  • Oil vapor leads to product contamination

  • Particulates clog air tools and valves

nstalling the right filter extends the life of your compressor and toolsImproves air quality and system performance
Reduces maintenance costs and equipment failure


What Does an Oil-Water Separator Moisture Filter Do?

Function Benefit
Removes condensed water Prevents rust and internal corrosion
Separates oil from the air Protects tools and ensures clean air delivery
Traps dust and particles Avoids clogs and wear on downstream equipment

This filter uses centrifugal force + filtration media to effectively separate oil and moisture.


H2: Do I Need a Filter on My Air Compressor?

Yes. If you're using your compressor for:

  • Spray painting

  • Sandblasting

  • Precision tools (e.g. CNC)

  • Food/beverage packaging

  • Medical/lab equipment

Then a filter is mandatory to ensure clean, dry, contaminant-free air.


H2: How Far Should a Filter Be from the Air Compressor?

Recommended Distance: 10 to 30 feet (3 to 9 meters) downstream from the compressor

Why?

  • This allows compressed air to cool, causing moisture to condense before entering the filter

  • Improves filtration efficiency

Install a cooling pipe or aftercooler if needed


H2: How to Change Air Filter on LG Linear Compressor Refrigerator

(Although different from an industrial air filter, we include this as it’s often searched together)

Steps:

  1. Locate the air filter at the back or top of the fridge compartment

  2. Twist counterclockwise to remove the old filter

  3. Insert the new filter and twist to lock it in place

  4. Reset the filter light (if available)

Use LG-certified filters for best performance.
