Sullair LS20-100: How to Read Gauges and Control Panel Warnings
If you operate a Sullair LS20-100 rotary stationary compressor, understanding your control panel isn’t optional. It’s essential. Reading your gauges correctly helps you avoid downtime, spot problems early, and keep your system running efficiently.
Key Gauges on Your LS20-100
1. Sump Pressure Gauge
Indicates the internal pressure inside the sump (oil separator tank). Abnormally high sump pressure can signal a plugged separator or discharge restriction, while low pressure might indicate air leaks or valve issues.
2. Discharge Temperature Gauge
Shows the temperature of air leaving the compressor element. High discharge temperatures often point to cooling issues, low oil levels, or restricted airflow.
3. Oil Filter Differential Gauge
Measures the pressure drop across the oil filter. A high differential suggests a clogged filter that needs replacement, which can reduce oil flow and increase wear on critical parts.
4. Separator Differential Gauge
Shows the pressure difference across the air/oil separator element. A rising differential usually means the separator is becoming plugged and should be replaced to avoid higher energy costs and oil carryover.
Control Panel Warnings and Alarms
Your LS20-100 is equipped with indicator lights or digital alerts for key parameters like high temperature shutdown, low oil level, high pressure, and maintenance intervals. Ignoring these warnings can lead to catastrophic failures or unplanned shutdowns.
Why Understanding These Readings Matters
Being proactive with gauge readings allows you to correct issues before they become expensive problems. Routine monitoring not only protects your investment but also improves uptime and overall efficiency.
