Great Lakes Air Compressed Air Dryer GBS-3000

Warning: This maintenance check requires trained personnel with PPE!

Purge mufflers preventing high noise levels?

Muffler elements clogged due to desiccant fines?

If muffler elements are clogged, replace them.

Purge tower showing backpressure during operation?

If purge tower shows backpressure, replace the muffler element.

Desiccant dust accumulation prior to equipment startup?

If there is desiccant dust accumulation, clean it.

High volume of desiccant fines from startup?

Warning: This procedure requires trained personnel with PPE!

Check for contamination of desiccant

If contamination is found, report to the maintenance team and stop the procedure

Check the condition of the coalescing pre-filters

Drain spent desiccant through the desiccant drain port in the bottom of each tank

Is the desiccant oil contaminated?

If oil contamination is found, deal with it based on the amount of oil contamination

Add fresh desiccant through the desiccant fill port

Blower intake filter changed within the last 4 months?

If not, replace the filter immediately to avoid high motor amperages and elevated blower discharge temperatures.

Enter the filter differential in H²O

Is the filter differential below 10” of H²O?

If not, replace the filter immediately to avoid non-warranty blower failure.

Warning: The Blower Polishing and External Heated modes of operation require an adequate supply of purge air which is essential for proper regeneration of desiccant and good dewpoint suppression.

If your system pressure varies throughout the day, set the purge pressure at a low-pressure period so during those low-pressure periods the purge flow is not starved.

Always consult the factory prior to changing operating conditions.

Is the adjustable purge valve set to the standard conditions?

DO NOT operate the dryer with the purge valve closed the flow path is required in all modes for repressurization.
