Here’s a clear, practical checklist you can actually use in the field.

1. Install it correctly (this matters more than people think)

• Correct flow direction – always follow the arrow on the filter body

• Right size – undersized filters clog fast and cause pressure drop

• Proper mounting – vertical installation with the drain at the bottom is best

• No pipe stress – misaligned piping can crack the filter housing over time

2. Drain condensate regularly

Moisture is the #1 killer of gas filters.

• Drain daily or weekly depending on gas quality

• Use manual drain for routine checks, or automatic drain for continuous systems

• Never let condensate reach the filter element—it ruins filtration efficiency

3. Monitor pressure drop across the filter

This is your early-warning system.

• Install pressure gauges before and after the filter

• Normal condition: small, stable pressure difference

• Sudden increase = clogged element

• Sudden drop = damaged or bypassed element

👉 Set a pressure-drop limit and replace the element before it hits that value.

4. Clean or replace the filter element on schedule

• Follow the manufacturer’s service interval

• Replace sooner if:

  • Gas is dirty (rust, scale, oil)

  • Burner flame becomes unstable

  • Regulator or valve starts malfunctioning

⚠️ Never wash paper or fiber elements unless the manufacturer explicitly allows it.

5. Protect the filter from contamination

• Install the filter upstream of regulators, solenoid valves, and burners

• Keep pipeline clean after maintenance (flush lines before restarting)

• Use a coarse pre-filter if gas quality is poor

6. Inspect during routine maintenance

At least once per month:

• Check housing for corrosion or cracks

• Check seals and O-rings for hardening or leaks

• Verify drain valve operation

• Confirm no external gas leakage

7. Match the filter to gas type and conditions

Make sure the filter is suitable for:

• Gas type (natural gas, LPG, biogas, etc.)

• Operating pressure and temperature

• Filtration rating (micron size matched to burner and valve requirements)

Wrong filter = frequent failures downstream.

8. Keep maintenance records

Simple but powerful:

• Installation date

• Drain frequency

• Element replacement dates

• Pressure-drop trends

This helps you predict failures instead of reacting to them.

Bottom line

A gas filter stays in good condition when it is:
✔ Properly installed
✔ Regularly drained
✔ Monitored for pressure drop
✔ Serviced before it clogs
✔ Matched to the system
