I have a old industrial compressor 5hp, wire as 220v ,140-175psi ,the current pressure switch is a Furnas 69FJ9 and it needs to be replaced (its stuck) my pressure switch doe not have the upright brass fitting it is regulated internally , will this switch work or do you have another that will?
A: The unloader on the switch does not have to be used if there is another form of compensation in the system to relieve head pressure. The switch is rated for 25 amps continuously. If this will work with the draw of your motor, there shouldn't be any issues.
