Air Dryer – Weekly Operating Check

PRESSURE DEW POINT/ Target: 38°F (3°C) Provisional Acceptable Range: 35°F to 45°F (2°C to 7°C)

• Pass – Between 35°F and 45°F

• Attention – Above 45°F

• Fail – Above 50°F for a sustained period

• No high-dew-point alarm is active.

• No moisture or condensate is detected downstream.

Alarm Status:

• No Active Alarms

• Active Alarm

INLET COMPRESSED-AIR TEMPERATURE/Published Reference Condition: 100°F (38°C)

• Pass – Within the validated OEM operating limit

• Attention – Above 100°F

• Fail – Above the validated OEM maximum or high-temperature alarm active

INLET AIR PRESSURE/Published Reference Condition: 100 PSIG (6.9 bar)

• Pass – Within the approved plant-header range

• Attention – Outside the normal plant operating range

• Fail – Above the dryer nameplate maximum pressure

OUTLET AIR PRESSURE

• Pass – Stable and consistent with normal operating demand

• Attention – Abnormal fluctuation or lower than expected

• Fail – Insufficient pressure for the process

Pressure Drop/ Calculate: Inlet Pressure: __________ PSIG Outlet Pressure: __________ PSIG

FINAL ACCEPTANCE CHECK

• Pressure dew point is within the provisional acceptable range.

• Pressure drop is 3 PSI or less.

• Inlet temperature is within the validated OEM limit

• Inlet pressure is within the approved plant-header range.

• No active alarms are displayed.

• No visible moisture or condensate is present downstream.

• Automatic condensate drain operates correctly.

• Readings are stable compared with previous inspections.
