Wrong pressure switch on Speedaire 2Z498
(Wood-Ridge, NJ USA)
Speedaire 2Z498 air compressor
I inherited a Speedaire 2Z498, with a Dayton 1/2 hp motor model 6K178-B, and a 3 gallon tank (1Z782 - 3034).
It has no relief valve and what I believe to be the wrong pressure switch. It has a Ranco refrigeration pressure switch, which seems to work opposite of what it needs. When the pressure builds up, the switch turns on.
Can you tell me what pressure switch I need and what relief valve I need - and where to buy them?
Also, what is the maximum pressure of this unit?
