How to Maintain Your SS3 or SS5 Compressor in Humid Environments
Humidity can be your compressor’s worst enemy. If you operate an Ingersoll Rand SS3 or SS5 in a humid environment, extra care is needed to protect your system from excess moisture, rust, and sludge buildup.
Why Humidity is a Problem
When humid air is compressed, moisture condenses inside the tank and lines. Without proper maintenance, this can lead to:
- Internal tank corrosion and weakened welds
- Water carryover to tools and spray equipment
- Oil sludge or emulsification in the pump
Daily Tank Draining is a Must
In humid regions, daily draining isn’t optional - it’s critical. Open the tank drain valve at the end of every day to remove accumulated water and prevent rust from forming inside the receiver tank.
Check Your Oil Condition More Often
Moisture can contaminate the crankcase oil, turning it milky or sludge-like. Inspect oil condition regularly and stick to a strict oil change schedule. We recommend using All Season Select synthetic lubricant for added protection against thermal and moisture breakdown.
Keep Your Air Filter Clean
A dirty or clogged air filter can further reduce air quality and lead to more condensate. Check and replace your filter more frequently if you’re in a humid environment. Find the correct filters here (and as a disclaimer - not all machines are alike - but these are a few standard filters):
Consider Adding an Air Dryer
If you use air tools or spray equipment sensitive to moisture, adding an inline air dryer can drastically improve air quality and protect downstream equipment.
Beat the Moisture and Keep Running Strong
By taking these extra precautions, you’ll prevent premature wear, reduce repairs, and keep your SS3 or SS5 performing at its best, no matter how sticky it gets outside.
