what gas do you use to precharge one of these bladder accumulators? heard some folks use regular compressed air but wanted to check before i hook anything up
Answer by: Customer Support on Dec 16, 2025, 6:53 AM
Dry nitrogen gas only. Compressed air carries moisture and oxygen, which can cause bladder degradation and create a hazardous condition inside the shell. Never run this unit without a proper precharge in place either, that step is not optional for safe operation.
